Tractors from rebuilt spare parts. Homemade minitractor. What version of the homemade mini tractor to choose

Agricultural motoblocks have one serious drawback - the operator has to walk on foot along the area being processed together with them. As a result, fatigue occurs rather quickly, and the time of performance increases, which leads to a sharp decrease in labor efficiency. Another thing is a mini-tractor that has a full wheel base and steering. But not everyone may afford to buy such a technique. Therefore, in an agricultural environment, self-made minitractors, which are constructed on the basis of professional or semi-professional motoblocks in the agricultural medium.

Alteration of a motoblock into a minitractor: Highlights

In contrast to amateur equipment, professional and semi-professional has greater and power. For example, from a motoblock with a diesel engine by 9 hp You can make a completely decent mini tractor for plowing and cultivation. In the final score, it all depends on the purposes that the owner of the modifiable technique is going to reach.

Construction and assembly of a homemade minitractor - the task is not simple, but perfect. And for its successful solution, it is necessary to focus on two points:

Development of body and frame, as well as the schemes of their connection with the base of the mini-tractor - the motor-block.
Development of the kinematic scheme.

Frame and homemade body are performed from metal corners or profiled pipes. When calculating the design, it is necessary to consider the ratio of its weight with the power of the motor, as well as the resistance that the machine will overcome when performing various types of work.

If you choose a powerful fiberboard as the basis for a homemade minitractor, it allows you to use ready-made automotive or motorcycle trailers. Moreover, leading manufacturers of motoblocks have long provide a constructive possibility of connecting such trailers to the manufactured technique.

The kinematic scheme of the self-made mini-tractor is a complex of constructive solutions that provide torque transmission from the engine of the motor-block to the leading (predominantly rear) wheels. When calculating, it is necessary to distribute the load on the leading axis uniformly - from this directly depend on both reliability and durability and functionality, that is, the possibilities of using the technique.

Minitractor do it yourself: where to start?

In fact, there are many options for self-constructing a minitractor. However, the principles are used everywhere approximately the same:

Deployed towards the operator and fixed on the frame.
Control is implemented using steering.
Used hydraulic drum brake.
For brakes and clutch uses pedal control.
Manual control is used for accelerator and mounted equipment.
The operator seat is placed above the rear axle.

One of the most simple ways to create a minitractor with your own hands is the purchase of an adapter - a two-wheeled trolley with a seat for the operator and the aggregate system (to install mounted equipment).

Obviously, various parts will need for the assembly of a minitractor. They can be easily found among the automotive. For example, drum brake for leading wheels, steering rack and pedal control nodes can be taken from a passenger car VAZ. In the same way, the trail in the auto parts market is also selected, both the seat, and other structural parts for a homemade mini tractor.

But besides the spare parts, it is necessary to have a whole arsenal of the instrument at hand and a whole tool - welding machine, drill, disk saw, wrench, etc. And it is very desirable that in the process of assembling a minitractor you have access to a specially equipped workshop or if necessary, you could use the services of specialists in welding, milling, plumbing and emergency repair.

Rama minitractor

The chassis is the basis of a minitractor. Its main quality should be reliability, but you need to closely monitor the total weight of the structure, in order to ensure the normal clutch of the wheel base with the soil when performing work and at the same time do not overload the engine.

For the manufacture of a frame of the homemade minitractor of the middle power, a lightweight channel, a profiled pipe or metal corner suitable. Dimensions of the design, the assembly of which is performed by the method of welding, must be responsible for the sizes of the machine. By the contour of the frame, it is necessary to perform holes for hiding and fixing the structural elements of the minitractor.

The weight ratio of the frame and its strength should be optimal. It is not necessary to overload the design with additional ribbies, as well as saving on the metal, sacrificing common indicators of reliability.

Before you begin assembling the frame, you need to decide on which trailers and you are going to use when working with it. And in order not to lose the thought in the process of design, before starting work, drawings should perform drawings of the future machine and its main nodes with the main sizes. To do this, you can use the finished documentation that you want to adapt to the specific parameters of your minitractor.

Front and rear bridges

These nodes are created from individual spare parts and components taken from passenger or even trucks or other agricultural machinery. However, some details, like the assembly itself, you will come to perform yourself.

To make the front axle, you will need:

transverse beam;
sleeves of supporting rotary axes;
axes sleeve;
wheels of wheels;
(ball and roller);
bolt connections.

With the function of the transverse beam perfectly cope with the segment of the profiled pipe or metal corner. For the manufacture of sleeves of the semi-axes, structural steel 45. The support-rotary bushings are performed from the profiled tube, improved by the installation of bearings, and closed with steel covers made of steel grade St3. The front axle assembly consisting of a cylindrical clip and roller bearings is welded in the center of the transverse beam. With the help of large bolts, the bridge must be fixed to the sleeves in the cross-beam frame.

The power of the bolt joints is responsible for the magnitude of the back of the front axle relative to the design of a minitractor. Too hard, as well as too freely, fixing is negatively reflected on comfort in control, so the backlash should be optimal.

Similarly, the assembly of the rear axle is performed. The finished design can be borrowed, say, from the car UAZ. A long stocking of such a bridge will need to shorten - so it is possible to use standard short semi-axes. It will not hurt to protect the rear axle, and rather its welded connections from possible beats during operation. To do this, the caliper is applied - a metal corner, superimposed along the welds of the prefabricated construction of the bridge.

Wheel base and kinematic scheme

The choice of wheels for a homemade minitractor deserves separate attention. It is possible to use wheels from the passenger car, but dimension should be observed here. The optimal dimensions for the wheels are 12-14 inches. When choosing a smaller diameter, there is a risk that the machine in the process of operation will be burned with a nose into the ground. On the other hand, if the front wheels are too large, the operator for making maneuvers will have to apply non-hearth efforts. However, to facilitate the process of managing the machine, you can always use a power steering from a passenger car or other agricultural machinery.

Tires of a minitractor should have developed primrates. This will increase machine maneuverability, reduce the load on the running part and facilitates the management process.

As for the kinematic scheme, it is better to use ready-made options, whose search currently does not take a lot of effort. The scheme must be adapted to the settings of the nodes that you intend to use to create a minitractor. It will notice will not be able to consider the possibility of connecting attachments, which will repeatedly increase the functionality of the self-made machine.

Management system and operator seat

After the manufacture and installation of the chassis, you can proceed to the implementation of the kinematic circuit and the installation of the control system. The most important thing in this business is to properly place. With this role, the front seat will perfectly cope with a car, which is easy to find on car services and in workshops involved in disassembling vehicles.

The steering wheel must be installed on an optimal height operator. The steering wheel should not interfere with the free placement of the knees - it must be fixed so that in the sitting position the work with it did not cause discomfort.

All the necessary details for pedal, manual and lever control of the machine and its functional nodes can be found in the same place where the seat and all other parts are in workshops or on the market.

Engine installation and body improvement

After assembling the chassis, the implementation of the kinematic scheme and the installation of the operator's seat with the control system can be started to install the main unit of the minitractor - the engine. For its reliable fixation on the frame, you should use a special slab with grooves - it will give the chassis additional rigidity. Next, you need to pave electrical and mechanical control circuits, connect and configure the operation of the control system.

The body's casing is performed at the request of the user, however, some nodes and structural elements are still better to close. This will prevent their pollution and failure in case of contact with outsiders and soil.

When conducting a private farm, it is simply not to do without a tractor, although with the most small dimensions.

Especially if someone constantly lives outside the city. It is the miniature varieties of technology to become the best solution for this task. You can purchase equipment from the well-known manufacturer, but the option of creating homemade mini tractors for the household is simpler. This will save on cash spending.

What option is better suited for a homemade minitractor

Machine with a broken frame by many recognized as the optimal option. In such an unit, only two parts:

Rear
Front.

The clutch is carried out using a special hinge mechanism. All control mechanisms are located in front. The same applies to the chassis. Steering wheel and hydraulic cylinders become the main designs involved in the management. On the hinge, the design is perfectly bent.

Due to which the mutual location of both parts of the tractor changes. Such a device will save on the purchase of details, without which the installation is not possible.

Compared to the front, the rear of this combine has a simpler device. One of the main parts is the rear axle. It is fixed with your own hands in the lifes, on the spars at the semi-axes.

Then this design is used to install the driver's seat. Here is the device for fastening attachments of equipment.

The semi-axes together with the differential can be taken from the loaders, even if they were already in use. It is allowed to create a suspension for the rear, but not always this solution will be justified. Little pressure in wheels are enough to create depreciation.

Such a household tractor differs not only by simple design, but also by other advantages:

Low cost assembly aggregates. You can apply structural elements with a much more affordable price than what is going in the factory.
Small fuel consumption. The indicator is determined by the constructive features of each specific model, but more often it retains a low level.
The ability to turn around, even if the area is minimal. The broken frame design contributes to the minimal reversal radius. In almost one place, the technique can turn on 360 degrees. When plowing the Earth, this property will bring especially much benefit.
High production capacity.

Collect a small tractor from a motor-block

The homemade minitractor 4 for 2 centimeters can already cope with most of the necessary functions. It will be enough to prepare such details as:

Driving seat of small sizes.
Signal lights.
Hubs.
Traction.
Wheels.
Frame. Constructed from metal corners, or profile pipes.

A simple hydraulic attachment is enough to ensure uninterrupted operation of technology. It makes it possible to add hinged equipment. Which is chosen depending on these or other types of work.

When the details themselves are ready, you can move to the direct assembly process with your own hands. Of the additional tools, you will need a welding device with an electric drill, a wrench and a hammer. The assembly process takes no more than a few days.

What other details can be used in work

You can use details from old cars if the need for them disappears. It does not matter, there is a question of domestic or foreign manufacturers.

The design can be equipped with a large amount of attached, trailed equipment. It is for this reason that the motoblocks are considered universal assistants in the farm. It can be used for any work related to the processing of the Earth.

It is possible to operate the tractor together with the cart, which only has one axis. Then it will be possible to engage in the carriage of various materials, including sand or soil, construction and other trash of small dimensions. The driver is on the seat with springs, in front of the cart.

In the self-sized tractors of this type there are such details:

Trailed mechanism.
Devices with which control is performed.
Mechanism in the chassis.
A device that allows you to adjust the power.
Transmission.
Electric engine available in the VP-150M series.

On the frame of the square shape, almost all elements are placed with their own hands. The frame itself can be built using a channel. Electric motors from pump scooters of domestic producers will be the best motoblock options. It is permissible to use analogs that have a power up to 5.5 kW. The main thing is that the device itself is single-cylinder.

Such models have a built-in gearbox, which is installed in advance. A mandatory element of the design becomes clutch clutch along with electronic type ignition. The centrifugal fan complements the overall picture. The engines without this device require permanent cooling manually.

Oh drawings

At the first stage, it is necessary to thoroughly think about what kind of tractor will have. The clutch diagram of parts also does not allow errors. The basis of the fundamentals therefore the drawings are drawn up according to all the rules.

It is better to use outsiders to search for suitable options. But only if the accuracy of information does not cause any doubt.

All items must be positioned so that they can interact with each other qualitatively. The driver's place together with the main nodes is applied with their own hands on the drawings, first of all. The mechanic help will not be superfluous if someone doubts his skills.

There are three groups of spare parts requiring increased attention: gearbox, chassis and engine. It is best to remove them all from the same type of equipment. Then there will be no need for fitting.

Transmission and engine: right choice

The choice of the owner seems small. It is required to find what best is suitable according to the available characteristics. There are two varieties of the engine, which will be the best solution, by economic indicators and performance:

UD-2.
UD-4.

But it is permissible to use any engine that has one cylinder. The maximum allowable amount in the design is two. If you manage to find the M67 option, it is recommended to apply it. The main characteristic is a long service life, although maintenance and repair costs remain minimal. This is one of the answers to the question of how to make a mini technique for servicing the economy.

Its engine must be upgraded before starting the installation. This is necessary to increase the gear ratios, creating a competent cooling system. After all, it is originally missing. Cooling is carried out with a fan, which is fixed on the crankshaft, and is supplied with a suburban casing that guides the air flow.

Motors from old Muscovites with Zhiguli can also become power units for such devices. If the engines are extracted from cars, then simultaneously make the gearbox with transmissions. Then you will not have to look for suitable details, make fit.

The wheels should be chosen depending on the purposes that transport is used. Discs for 16 inches are suitable for those who plan to transport cargo, carry out a dragging and so on. But with wild work, more massive structures are better coping with, up to 18-24 inches. Such characteristics improve the adhesion with the road.

In conclusion: Some features of installation

The supply of hydraulic cylinders is mandatory for the control system, which is supplied with a minitractor. In this case, the vehicle will not deliver trouble during operation. Maximum attention requires the regulation of such an indicator as a gear ratio. It is recommended to exhibit with minor turns. Otherwise, the tractor can develop too much speed.

For all wheels use a hard, independent suspension. It is better to provide the possibility of rotation for the frame, at least 15 degrees. Then, when passing a complex part of the wheels, they will not sign, nor in front, nor from behind. In a breaking system, you can implement the swivel from the UAZ. It is installed in the front of the semiracy. The limiter will help protect against unnecessary coups.

We get a car with maximum practicality. Able to solve any tasks arising from the conduct of the household. Useful will be the ability to cling additional devices.

The use of minitractors in agriculture becomes more and more justified lately. Relatively small dimensions, coupled with good performance and maneuverability, allow to process land ownership for their further use. However, not everyone has the possibility of acquiring a finished unit selling in a specialized store, because it can cost up to 100 thousand rubles. It is then that many questions arise from many - how to assemble a minitractor at home with your own hands?

The solution is not such a simple, as it may seem at first glance, because for the implementation of the assembly, there may be quite a few concomitant material, as well as the necessary technical knowledge and the ability to work with the toolkit.

Applications of the homemade minitractor in the household

And in general, you can use the Internet by driven into the address bar "Minitractor do it yourself drawings sizes", and you will immediately see any detailed assembly scheme.

Rama, is a supporting structure. All attachments attached to it.

This step is very important, because the independent manufacture of a unit involves a certain refinement and fitting for the necessary parameters. Obviously, it is easier to carry out this in the drawing than to navigate approximately.

For successful and productive housekeeping, an appropriate agricultural machinery is necessary. Turning on the link to familiarize yourself how to make a cultivator yourself.

Plows have improved characteristics, which makes it possible to cope with the plowing of any land as quickly and efficiently as possible. All about various types and characteristics of PSK.

Currently, technical progress helps to replace long human labor for much more operational operations of machines. Grafsee's grain harvest is your indispensable assistant with excellent quality for decades.

In addition, it will be clear to the same Tokary that it takes from it by looking at a detailed drawing than a formal explanation in words.

At the project planning stage, and it turns out exactly which unit will be in the end. Many have a certain popularity of a minitractor of a fracture with their own hands at home located on the articulated frame.

However, this is not the only way to build, so the choice lies solely on that person who will carry out the manufacture.

Deciding with the type of minitractor, the question arises about the search for the necessary spare parts and components. We are talking about frame structures, engine, transmission, controls and wheelbase. Most of this can be found on the Internet by visiting sites specializing in the realization of various spare parts.

The assembly process itself will include several stages:

Making frame. The fracture is carried out mainly from the channel number 5 and channel number 9. From these components you need to cook two semirams, and they will be connected with each other with a hinge. In this capacity, you can use drive shafts from heavy trucks.

There is another way to design a frame. It lies in the manufacture of a solid design consisting of two traverses and two spars. Traverts are made from channel number 16 (for the rear) and number 12 (for the front).
The spars will be made from the channel number 10. A timber from metal is used as crossbar.
As an engine, you can use MT-9, UD-2, UD-4, and PR. Their power will be quite enough for the self-made option. In principle, any engine with a relatively high power is suitable - approximately 40 hp
Both and the gearbox can be removed from GAZ-53, and the clutch take from GAZ-52. Remember that the details will have to be customized under the design parameters. A motor flywheel needs to cut a little back, as well as drill a hole in the center.
The steering wheel can be provided with a hydraulic system that needs to be taken with old agricultural machinery.
The design of the rear axle can be borrowed from old cars, but it will have to correct it to the lathe on the lathe.
You can use any suitable as wheels, but that their diameter is about 18 inches is a permissible minimum for agricultural work.
In this sequence, in principle, the answer lies to the question - how to make a minitractor at home? Most of the necessary components can be obtained from old technology, which greatly simplifies the search for the search for the desired detail.

In addition, the costs are minimal, because even the purchased items will cost much less than the finished minitractor.

Advantages and disadvantages of manual assembly

Perhaps the main advantage of the homemade minitractor is the unconditional savings of funds, compared with the acquisition of full-fledged units in the store, such as Uralets, Cubot, Bulat 120, Yanmar, Belarus 132n, scout.

At the same time, his working indicators will dismremely different from the factory options, because the design uses a fairly powerful motor, which is enough to process land possessions, up to ten hectares.

The cost of making on a minitractor pays for almost one calendar year, because most of the components are taken from the old technique, or the cost of their acquisition is minimal. Many adapt to a minitractor to other techniques, such as a motoblock, which further simplifies the assembly process.

In addition, self-made aggregates have other advantages:

Relatively large degree of immersion in the soil. If everything competently foresee, the depth of the epigation will be identical to the one that shows purchased counterparts. Be that as it may, it is still better than to drag the garden manually.
Quite high mobility, as a result of sufficiently modest dimensions. The use of such aggregates is advisable precisely on small gardens and summer cottages, where the large-sized tractors do not turn around.
Due to the fact that you make a minitractor ourselves, there is an opportunity to further upgrade the unit. You can shoot components by changing them to other, more powerful, or add new devices.
In the network sold, such an opportunity is absent, moreover, in the instructions for the operation, it is directly written that the introduction of any changes to the configuration is strictly prohibited.

Among the shortcomings, the following points can be noted:

Relatively complex assembly process. Here we are talking not only about direct work, but also about certain difficulties in the selection of the necessary components. Many of them have to customize on the lathe, which in itself is an additional complexity.
The probability of breakdowns, because the homemade version is made mainly from old parts and spare parts.

In principle, the pros and cons are approximately equal to the degree of their importance, but there is one small retreat. Today's realities are such that the question of the price becomes dominant, overshadowing other arguments.

A detailed explanation of this phenomenon is superfluous, because savings has always been decisive, regardless of where it is applied.

Additional tips and warnings for the manufacture of the tractor do it yourself

Before starting a full-fledged exploitation, a homemade minitractor, you need to register it into account in the traffic police.

This is not a simple formality, but an explanatory need, because when moving on public roads, you can impose a penalty sanctions on you, and the aggregate itself is transported to the free-kick.

As for technical aspects, then there is its own specificity. In order for the engine of the homemade unit to issue the desired parameters, i.e. About 2 thousand revolutions at 3 km / h, you need to correctly correct the transmission scheme. In general, ideally, each rear axle wheel should be equipped with a gearbox.

If the basis for a minitractor performs a motoblock, such as Cayman, Patriot, Texas, foreman, Viking, forz or some other, then it is better that he possessed a special coupling that allows you to attach additional equipment to it. In general, you should carefully choose the model of the motoblock you want to remake under the minitractor.

For these purposes, the "Centaur" motoblock can be perfectly fitting with a capacity of 9 hp, as well as the necessary technical data necessary for alterations.

Conclusion

The manufacture of a homemade minitractor is becoming increasingly relevant, especially for owners of small land plots. The fact is that the use of large-sized tractors may be inappropriate, because they will not be able to show all their working performance on such a small plot of land.

In addition, fuel costs can become truly inexpermissioning non-private farmers.

The savings also explains the refusal to acquire a minitractor in a special store, because agriculture is far from the most profitable type of business in our country. Therefore, for the usual dachanik, the optimal option will be the manufacture of an aggregate with its own forces.

Costs are penny, and the performance of the finished home-made minitractor can pleasantly surprise you. Naturally, if you use a relatively powerful engine and not very old spare parts.

Do not forget that this method may not be suitable for some persons who do not have due skills in handling the welding machine or turning machine, for example. In this case, you can simply order the necessary details from the masters that will be manufactured.

You will have to pay, of course, but no more than the amount you need to pay for the finished minitractor.

Alteration of a motoblock into a minitractor: Highlights

Construction and assembly of a homemade minitractor - the task is not simple, but perfect. And for its successful solution, it is necessary to focus on two points:

Development of body and frame, as well as the schemes of their connection with the base of the mini-tractor - the motor-block.
Development of the kinematic scheme.

If you choose a powerful fiberboard as the basis for a homemade minitractor, it allows you to use ready-made automotive or motorcycle trailers. Moreover, leading manufacturers of motoblocks have long provide a constructive possibility of connecting such trailers to the manufactured technique.

Minitractor do it yourself: where to start?

In fact, there are many options for self-constructing a minitractor. However, the principles are used everywhere approximately the same:

deployed towards the operator and fixed on the frame.
Control is implemented using steering.
Used hydraulic drum brake.
For brakes and clutch uses pedal control.
Manual control is used for accelerator and mounted equipment.
The operator seat is placed above the rear axle.

One of the most simple ways to create a minitractor with your own hands is the purchase of an adapter - a two-wheeled trolley with a seat for the operator and the aggregate system (to install mounted equipment).

Rama minitractor

The weight ratio of the frame and its strength should be optimal. It is not necessary to overload the design with additional ribbies, as well as saving on the metal, sacrificing common indicators of reliability.

Front and rear bridges

To make the front axle, you will need:

transverse beam;
sleeves of supporting rotary axes;
axes sleeve;
wheels of wheels;
(ball and roller);
bolt connections.

The power of the bolt joints is responsible for the magnitude of the back of the front axle relative to the design of a minitractor. Too hard, as well as too freely, fixing is negatively reflected on comfort in control, so the backlash should be optimal.

Wheel base and kinematic scheme

Tires of a minitractor should have developed primrates. This will increase machine maneuverability, reduce the load on the running part and facilitates the management process.

Management system and operator seat

All the necessary details for pedal, manual and lever control of the machine and its functional nodes can be found in the same place where the seat and all other parts are in workshops or on the market.

Engine installation and body improvement

Work in the field of agriculture in the majority is associated with land processing. But for sowing and growing crops, berries and vegetables, as well as fruits, it is necessary to plow the ground, adding it to fertilizers and providing watering, as well as a weeding. If the farmer has specialized techniques, work can be significantly simplified. Such equipment has small sizes, but copes with the main tasks quite successfully. Among them should be allocated:

loose;
plowing of the earth;
grass mowing.

To solve this issue, firms and large agro-commoms are suitable using domestic and imported models. If you are the owner of a private farm, you can be limited in financial opportunities. In this case, it will have to use a mini-tractor, possibly manufactured independently.

This will save, but it is worth being prepared for the fact that the assembly of such equipment is accompanied by certain difficulties. Many this does not stop, because in the forces of each farmer produce such a minitractor independently, additionally equipped with its equipment to solve a wide range of tasks.

Basic varieties of homemade tractors

The tractor for the farm can belong to one of several varieties, among them:

multifunctional technique;
homemade tractors with garbage cleaning function and grass rest;
rider.

The first species is the equipment with which you can process the soil, remove the garbage, and cut down the grass. Homemade tractors are usually equipped with power units of medium power. Multifunctional technique can cope with an area of \u200b\u200b6 hectares. If necessary, you can install hinged equipment, thanks to which the task list is expanding.

Homemade tractors on wheels can be designed to perform a narrow circle of tasks, they are used to process the area to 2 hectares or lawns. Rider are needed for fertilizers, as well as processing by pesticides. They can use equipment in order to fulfill other tasks when there is a need for a small land processing.

Features of tractor manufacturing

If you decide to perform a homemade tractor with your own hands, then at the first stage you will need to perform a frame for which the rolling channel is used. There are traverses in the design, and they will arrange them from behind and in front. In addition, the system has Longlers. When the frame is created, the width of the frontal part slightly decreases, which gives the part of the trapezoidal form. A hole must be created in the frame, thanks to which other devices and elements can be strengthened.

Methods of work

When the homemade tractor is made with their own hands, it is necessary to use racks that should be welded to the corners. They will perform the function of the subframe. They should be additionally connected in the upper part. On the frame you need to install the rear axle.

Sometimes the project involves the assembly of the all-wheel drive tractor, in which case the front axle should be located on the frame. The homemade tractor is made with their own hands using the engine. The most suitable option will be the motorcycle motor. For mounting the gearbox on the frame, it is necessary to find a place. The box should be located so that the driver is more convenient to manage it.

Now you can proceed to install steering elements. For this, the steering wheel is usually used. This item borrow, as a rule, at the model of a passenger domestic car. In some cases, the steering wheel from the motorcycle is used. For the trailer you will need a hitch. It is installed at the next stage, welding to the frame. When a homemade tractor is made with her own hands, a braking system and tank are needed, which should move to the electrical connection.

Assembly Instructions: Frame

The homemade tractor may seem disproportionate and non-compound. In fact, if the mechanism is to collect correctly, and all key nodes will be rationally, the system will work properly, performing all tasks set before it. Extra elements of the frame are traverse.

The spar is assembled from consecutive steps, the internal consist of a square steel pipe, while the outer-skewler. The front traverse should be less than the back. This indicates that the 12th size channel is suitable for the front traverse, while the 16th sized channel is for the rear.

Power unit, bridge and caterpillar

Before making a tractor, you must pick up the engine of the desired power and torque. Sometimes a four-cylinder diesel is used for this, the power of which is 40 liters. from. Such an aggregate has water cooling. As for the bridge, it can be installed without additional adjustments. It can be borrowed from a domestic truck, integrating into homemade techniques.

Before making a tractor, you must take care of the presence of the caterpillar. The easiest option is the design with rollers from tires and wheels. They can be taken from carts. Considering the size of the tractor, the wheels should be selected. The caterpillar can be made of a large tire, which is pre-trimmed on the sides.

Additional equipment tractor engine

The homemade tractor with the VAZ engine can be found quite often, as well as installations of the following types:

M-67;
UD-2;
MT-9;
UD-4.

You can equip the tractor engine from the Moskvich car or "Zhiguli". When it is assumed to be made by homemade according to the 4x4 formula, for M-67 increase the gear ratio of the transmission. Otherwise, the power plant will experience a lack of power to ensure efforts for wheeled steam. It must be borne in mind that an additional cooling system may be needed for the power unit.

Additional information about the transmission

A homemade tractor with a VAZ engine can be supplemented with a power take-off shaft and a gearbox that should be borrowed from the GAZ-53 car. The clutch can be taken from GAZ-52. These nodes will not work in the finished form. You should adjust.

In order to synchronize the engine with the clutch, you need to prepare a new clutch basket, to fit it under dimensions. The rear plane at the engine flywheel is shortened, an extra hole is drilled in the center. These manipulations can be performed on the lathe.

What else you need to know about the rear axle and wheels

The mini-tractor for snow cleaning can be equipped with a rear axle from a cargo or car. The half-axis is pre-triggered on the lathe. If the finished bridge failed to find, the design from different machines can be used. Specialists recommend using any node that is suitable in size, because the front axle does not act as a lead.

Wheels should be selected by radius. If the equipment is supposed to be used to transport goods, it is better to prefer wheels, the diameter of which varies from 13 to 16 inches. For technology, which will be involved in agricultural work, you can use wheels with a radius ranging from 18 to 24 inches.

Equipment of homemade tractor

The configuration of the described technique includes a frame on the homemade tractor. After assembly, it is necessary to install leading wheels and support rollers. The power unit is mounted in the next step, then it comes a turn of the transmission. Differentials and onboard brakes must be installed in the next step, after can be connected to the gearbox all components.

The next step will be the assembly of controls, as well as the workplace arrangement. Additional parts and caterpillars can be installed at the next stage. Now the master will have to check the manufacture of the tractor, improving its individual nodes if necessary.

Conclusion

The mini tractor for snow harvesting will show its abilities even when processing the soil. However, in order to achieve two thousand engine revolutions at a speed of 3 km / h, you need to adjust the transmission. Each rear axle wheel in the ideal version must be supplemented with a separate gearbox.

The advantages of homemade tractors are obvious. They can independently make every person, the cost of parts on such devices is lower than that factory, they perfectly cope with the processing of small areas of land. In addition, many parts for a self-made tractor can be found in their farm.

Consider in detail the question of how to make the tractor with your own hands.

Despite that any tractor, whether it is standard sizes or a motorotractor, consists at least from hundreds, and even thousands of details, it will be able to assemble him independently, who will master the scheme depicted in the form of an uncomplicated drawing. Due to the schematic drawing, the tractor assembly is similar to the standard designer, where the element A is connected to the element B, then the part of AB with the C element and so on the chain.

Although, it is worth noting that in our country there must be enough self-taped masters, which can "keep the drawing in the head", that is, to perform the same consistent actions as with the drawing, just follow the imaginary instructions. However, this concerns not all. Who does not have such experience, it is unlikely that it is unlikely to collect any kind of design, without referring to the help of a predetermined scheme.

In case, with the draw in school, you had a "bad relationship" and you are not able to organize a drawing of a full-fledged home-made tractor scheme, ask for friends, friends or loved ones that are better than you. In the extreme case, google-search will help you find any information.

Before starting the scheme itself, determine what exactly the tractor want to do, on the basis of which it will be manufactured. So, for example, homemade tractors can be:

tracked;
wheel.

They are manufactured on the basis of:

motoblocks. Very popular tractor from Niva (one of the most famous motoblocks in the Russian Federation);
car engines. Moreover, motors can be used as passenger cars and cargo, cargo-passenger. By the way, the GAZ-66 engine is very suitable for performing a homemade tractor with their own hands, which will have high power. Often there is a tractor from the UAZ;
UD-2 - a universal engine used as an additional motor in the installations that are equipped with an electric generator, as well as the engine in the tractor self-made tractor;
the people are popular with a homemade tractor 4 × 4. The homemade tractor 4 × 4 is also called a fracture.

Deciding with the above question, you can safely begin to drawings. At the same time, after creating a scheme, be sure to make a list of existing parts and nodes, and a list of those elements that need to be purchased, after which, buy missing spare parts. Only after the entire list of parts will lie in your garage, you can start an assembly of construction.

1.1 Constructive features

How to collect your own tractor? There are no big difficulties in this. If you correctly draw the scheme and prepared all the necessary details, the manufacture of the tractor turns into a practical part. The difference in modifications and options depends on the means and skills that you have. Below we describe the most optimal design:

If you choose on the manufacture of a tracked tractor with your own hands, because it does not damage the upper fertile soil layer, to simplify the new module, in the equipment of which there are wheels and the seat. Alternatively, all elements can be assembled independently at home. However, such a design will be deprived of the drive. The assembled, the caterpillar tractor is controlled by the turn of the transmission and motor block. To this end, it is recommended to use a standard steering wheel.

The motoblock should be complemented on the hinge module with the seat, for land work, it is also necessary to take care of the hitch. To implement this option, assemble the frame using a wheel pair and metal rolling. Then install two trailed knot on it, the seat. Do not set the wheels by shock absorbers, it will negatively affect the speed of the device.

2 Tractor assembly

There is a single recommendation that to take as the basis of the future unit and how to make a self-made tractor does not exist, which is affected by the availability of this or that technology in your farm from which homemade will be constructed. Therefore, it is advisable to consider various options. If you do not have a motoblock made on the basis of the Zhiguli, the tractor will be the assistant much better.

2.1 Tractor on the basis of Zhiguli

To build a tractor from the Zhiguli with your own hands, first of all, develop a kinetic scheme that takes into account the equilibrium design. The device will include: engine, rear and front axle, reverse reducer, cardan transmission. The engine will drive the front wheels. According to the circuit, the torque will be transmitted sequentially on the gearbox, the cardan transmission, etc. Leading rear wheels, as a result, will rotate.

Rama is made of pipes and corners. Keep track of the correct location of the fork and sleeve, providing a trailer turn. Metal sheets make body. The height of the sides should not exceed 30 cm. Next is mounted hinged equipment and driver's seat. After checking your unit for the performance. The final step is the primer and painting the surface of the metal elements.

2.2 Tractor with engine D-21

Many masters prefer to equip a homemade tractor with a Chinese engine. As a foundation takes Lifan, Forza, zener. However, experienced designers recommend putting a reliable Motor UD-2 or D-21. In the first case, the engine develops power to 8 hp, in the second - up to 25 hp Together with a 4-stroke system and air cooling, such an equipment is not only successfully operated for agricultural activities, but also for transporting goods. Consider the option with D-21 diesel.

To create a frame, take the pipe from the stacking agent. Pre-cut the half-frame borrowed from the T-25, to its front, weld the pipe, and to the rear metal sheet 3.5 × 50x50 cm. To the sheet with bolts, the hydrobacom and the hydraulic cylinder hidden are attached, which is also taken from T-25. The front axle is better to purchase in factory execution, otherwise there may be problems with semi-axes. Rubber wheels Take from GAZ-52, rubber from Belarus 82 (8.3 × 20), which is manufactured by the Minsk Tractor Plant.

The front wheels on the home-made tractor with the D-21 engine are set from T-25 (6.00-16). The hood, the beam is relatives, but over the fuel tank you need to pat. To do this, weld from a 3-mm leaf capacity by 40 liters. The finished product is located on the back of the tractor under the seat. Under the gearbox GAZ-52, output the transition slab. As a clutch, take a basket, fork and a frost bearing from the combine of Yenisei. Pre-remove half of the springs. The clutch disk is suitable any (both from gas and from the UAZ).

Out at the basket in the flywheel seat 3 mm. The Primary PPC shaft must be lengthened by 12.5 cm, the cardan transmission from GAZ-52 shorten. The connection must be collapsible. The steering column is purchased from GAZ-52. The hydraulics on the homemade tractor is assembled from the P-80 water distributor with a floating effect, the NSh-10 pump. It is placed through a fork connection in front of the engine. Preplays a regular bolt that is responsible for fastening the motor pulley.

You should not install the transmission pump through the power take-off box, since when the adhesion is pressed, the hydraulic system will turn off, the rotation speed will be unsatisfactory.

2.3 Tractor based on Oka

The tractor from the Oka do it with his own hands on the same principle as from the other Soviet cars. It all starts with the construction of the frame. Food with sheet gland and metal beams of the channel.

The design is a standard rectangular shape welded from metal corners. The front and rear axle are assembled from the components of the okey parts. The device is composed with an engine from the eye. However, the wheel is increased before installing the motor to improve the patency.

The rear and front spars are enhanced, since they laid the main load. Coupling mechanism should be provided for the installation of attachments. Drawings for further assembly can be found on the Internet. If you do not have the specified machine, it is not necessary to buy a new vehicle, the unit will fit and in idle state, since its individual elements are used.

2.4 Review of the homemade minitractor (video)

Homemade minitractor are ideal for handling small land. To collect a minitractor with your own hands can almost anyone who is a little disassembled in the technique.

According to specifications, homemade is significantly inferior to factory models. But using a powerful tractor in small areas at least not rational. Even service costs and fuel and lubricants are not justified. But a small tractor collected with her own hands, it turns out very appropriate. In this article we will tell you how to make a mini tractor at home.

Advantages and disadvantages of homemade minitractors

The mini-tractor, made by his own hands, is much cheaper than factory models, and for its functionality, it can sometimes give ourselves to more powerful tractors. Homemade can be used on vegetable garden and fruit gardens, for processing sowing areas (not exceeding 10 hectares), transportation of small cargo and cleaning.

The cost of such a car pays off literally in one season, After all, the main components and mechanisms are usually removed from broken technology or purchased at chasters. Some farmers are construed into a mini-tractor other technique. In this case, the manufacturing process is greatly simplified.

Of the disadvantages, you can note the difficulty in a selection of suitable parts. In addition, when setting out some nodes, problems with replacement or repair may occur. After all, no matter how cool, and the tractor is going from the older, so some details cannot be found.

To prevent drawings, you need to have technical skills and knowledge. After all, the mini-tractor should work with hinged and trailed equipment, for this it is necessary to calculate the traction force of the engine.

Tip! A mini-tractor assembled with their own hands, must be recorded in the traffic police. Otherwise, when leaving on the road, homemade can go to the penalty area, and you will write a cash fine.

We harvest the drawings

Some folk craftsmen are able to collect any technique, having only a bunch of old iron and a general work plan, which is held in the head. There are few people here and if you do not belong to their number, you must first prepare the drawings of the main nodes of the future machine.

If you do not possess the necessary knowledge, you can ask to make drawings of friends or acquaintances. Finally, the necessary information can be found on the Internet.

Having under hand drawings, a mini-tractor assembly at home will resemble a children's designer. That is, you take the item A and connect it with the coupling B.

It is worth noting that some nodes and parts, of which will consist of homemade, may need fit or additional processing. Agree, explain to the turner or the welder that it takes much more convenient from them on the fingers, and having a finished project and drawings at hand.

By the way, at this stage, you need to decide which mini tractor you want to make it yourself. Farmers are very popular with a filling of 4x4. This is a small model on the articulated (broken) frame, with a drive for four wheels. Such homemade is optimally suitable for work on farms.

How to assemble a mini tractor do it yourself

Preparation of diagrams and drawings, you need to find suitable parts. At a minimum, you will need the engine, transmission, frame and steering. It is very problematic to find the necessary details at home, so you can walk through the attacks and extract sites for the sale of spare parts. Here you can literally for a penny acquire the details you need.

Frame

A fracture is usually made from metal channel No. 5 or No. 9. The structure of this material has a sufficient margin of bending strength. Two semirases are welded from the channel, which are connected to a hinged joint. For these purposes, you can use drive trees from trucks.

If the fracture does not suit you, you can make a mini-tractor on a all-metal frame. This design usually consists of four elements: right and left side meters, front and rear traverses.

Soccerons can be made from Schweller No. 10, rear and front traverse from channels No. 16 and No. 12, respectively. Metal timber can be used as a transverse beam.

Engine

Transmission

For work, a mini tractor made with your own hands, you can equip any suitable power engine. The optimal option is a power plant with a capacity of 40 horsepower..

Most often, M-67, MT-9, UD-2 and UD-4 engines are installed on improvised units. There are models equipped with an engine from domestic cars of the Zhiguli series or Moskvich series.

If homemade will be manufactured according to the 4x4 formula, for the M-67 unit, it will be necessary to increase the gear ratio of the transmission, otherwise the power plant does not have enough power to provide the necessary effort for wheel steam. Please note that an additional cooling system may be needed for the power unit.

Transmission

The gearbox and the power take-off shaft can be removed from the GAZ-53 car. The clutch will suit the old GAZ-52. In the finished form, these nodes will not fit, you will need an additional fit.

To synchronize the clutch with the engine, you will need to cook a new clutch basket and adjust it for the necessary dimensions. The engine flywheel will need to shorten the rear plane and drill an additional hole in the center. These operations can be made on the lathe.

Steering

This node must include hydraulic cylinders, this will provide a mini-tractor of better handling. Do it yourself the system of hydraulics at home is impossible. Therefore, it is necessary to remove the finished hydraulic system with any agricultural machinery. Note that it will take a pump to circulate oil in hydraulics.

Rear axle

You can take a suitable knot from a passenger and truck and install on a homemade design. Previously need to shorten the semi-axes on the lathe.

If the finished bridge is not, the composite design is allowed from different machines. The front axle is not leading, so any node suitable for size is suitable.

Wheels

The radius of the wheels depends on how the mini tractor will be used. For transportation of goods, it is better to fit the wheels with a radius from 13 to 16 inches. To perform agricultural work, the wheels of 18-24 radius will be needed.

The mini-tractor made with their own hands, must issue about 2,000 engine speeds when plowing, at a speed of 3 km / h. To achieve such indicators, you need to adjust the transmission scheme.

In the perfect version, each wheel of the leading rear axle should be equipped with a separate gearbox. In this case, the rotation is set by a four-section hydrocratic distributor.

With such a steering pattern, the need for a cardan shaft and the rear axle differential is disappeared. Hydraulics will be responsible for managing wheels. The necessary equipment (pump and hydraulic cylinder) can be borrowed from the MTZ-80 tractor.

As you can see, make a minitractor with your own hands is quite simple. Despite the fact that this is a rather labor-intensive process, the result with interest will cover all the efforts spent. Moreover, collect homemade design, it is a very exciting occupation.

The presence of a plot of land imposes on its owner the obligation to ensure the care of it. And one of the urgent tasks to be solved - soil processing. Manually, such work can be performed if the area area is no more than 10 acres, and that is already problematic.

For large-sized territory you can use a homemade mini tractorwhich is the perfect option. At the same time, it is not necessary to acquire a mini-tractor from official distributors or at the factory, because such equipment can be collected with their own hands, it is enough to have at least minimal knowledge in the technique.

If you compare homemade machines with factory software according to specifications, then the superiority will be on the side of the latter. However, it is still incorrectly using new techniques for handling small land. Moreover, this is due not only to large expenditures related to the service and acquisition of fuel and lubricants. This technique may cause serious damage to the structure of the soil. Therefore, the homemade mini tractor is a much more preferred alternative. Then we will discuss how to collect a mini tractor at home.

Advantages and disadvantages of homemade mini tractors

If you need a land plot technique, then do not immediately discard the idea of \u200b\u200bcreating a mini tractor do it yourself. In addition to the fact that you can save considerable funds, you will have the opportunity to make such a car that can demonstrate much more functionality than the tractor with greater power. Mini-tractor homemade can be a faithful assistant for you, which can be used for plowing gardens and bookmarks of fruit gardens, as well as processing sowing areas, transportation of small cargo and harvesting.

BUT the cost of manufacturing such equipment is so smallthat one season is enough to reimburse all expenses. The fact is that for the manufacture of such a tractor, knots and mechanisms will be suitable, which can be borrowed from broken technology or to buy at bargaining prices. Some owners often show resourcefulness in this matter, and, taking as the basis of another technique, they make certain changes in it, as a result of which their home-made mini tractor appears. Naturally, in this case you will have to perform even less operations to collect a mini tractor.

Truth, there are some shortcomingswhich you need to mention. For the manufacture of a mini tractor, specific details will be required, which may not be so easy to find. With difficulties, it is possible to encounter and then when certain mechanisms fail, and it is not known whether it will be possible to find an equivalent replacement. It must be remembered that the assembly of such equipment uses nodes and mechanisms borrowed from long-poor equipment. Therefore, it is possible that it will not be possible to find certain details.

An important stage of manufacturing mini tractor homemade - drawing up the drawing. To do everything right, do not do without technical skills and knowledge. It should also be borne in mind that the mini tractor will be used with attachments and trailed equipment, and therefore the owner will have to calculate the traction force of the engine.

Drawing up drawings

Usually, when a person has a desire to collect any homemade technique, then everything starts with ideas. Some people can do without the work plan represented on paper, relying on their own knowledge in the technique. However, not everyone is as masters, so it will be better if you start the process of assembling a homemade mini tractor from the preparation of the drawing of the main nodes.

If it is difficult for you to solve this task, you can contact your friends if they had to do something like that. In extreme cases, you can use the Internet and try to find the necessary information there.

After you get a finished drawing, you can easily build a mini tractor. It will be no more difficult than the game in the children's designer. Schematically, the work will look like this: you will need to take the part A and connect it with the detail B.

Keep in mind that certain nodes and mechanisms will have to prepare before assembling the tractor. Remembering that you were borrowed from other techniques, most likely, their size and other characteristics will differ from the required. But, having a ready drawing on your hands, you can easily finalize all the mechanisms, because you will clearly know what they should be.

In the process of drawing up the drawing, it is important to solve the question of which design must have a mini-tractor. Quite often, farmers choose the version of the filling 4 x 4.

We are talking about the variant of the tractor in which the articulated frame is used, supplemented with a drive for 4 wheels. This technique will become an excellent option for processing farms.

How to assemble a mini tractor with your own hands?

After the drawing is compiled, you can prepare the necessary parts. You must have the following:

Not every owner will find the above items in his farm. Therefore, be prepared for the fact that you will have to break through the attacks, as well as look at sites for the sale of spare parts. Surely on one of them you will find the items you need at random prices.
