Rural life implies a large number of works characteristic of this type of terrain. Honor of manual labor nobody disputes, but the use of small mechanization means, in this case, can only be welcomed. However, not all categories of citizens have the opportunity to purchase a finished all-wheel drive minitractor in a special store, because the price of even the "cheap" model can be at least 50 thousand rubles.
There are different kinds of craftsmen, who has adapted to make such aggregates from all of that bread, which they have in the garage.
The fact that the negligent owner would drop into a landfill, a moderate and resourceful person can make a completely efficient device, which will be able to perform major agricultural work.
More popular, among such craftsmen, uses a mini-tractor 4x4 fracture with her own hands, which represents a fairly bizarre design.
The all-wheel drive minitractor made by his own hands has a sufficiently good characteristics of the passability, which gives him the opportunity to actually perform the same front of work as the store analogs, such as,.
The tractor is not necessary to buy - it can be collected with his own hands. There is an embodiment with a monolithic frame, which is easier, or with a broken - it will have to be tinted with it, but the car turns out a maneuverable one. The homemade mini tractor fracture 4x4 is completely constructed from elements of old cars and equipment.
The name "Refractory" Tractor received due to the frame, which consists of two parts. Before starting the assembly, you need to have a circuit with the size of nodes so that all the elements approached the dimensions.
4x4 tractor with a turning point with their own hands
This process can be described by the general scheme, but in practice, almost every self-taper collector contributes its own adjustments to the design.
For the assembly of a mini-tractor, the fractures usually adhere to the following requirements:
- The frame has a system of spars of 3-steps. For the front earning sewners number 10. The third stage is made from a pipe with a cut of 8 to 8 cm.
- The front traverse can be made from Schweller No. 12, for the rear, it is best to use №16.
- The crossbars are built on the same system.
- The engine is selected according to suitable characteristics - size, power, fastening type.
- Most often choose a 4-cylinder diesel engine for 40 liters. from.
- Liquid cooling allows the technique to work all day without overheating.
- The next step is to install the power selection shaft, gearbox, dispensing box. The details of the old gas-53 truck are ideal.
To connect the motor and the clutch, the remission of the flywheel is required - pruning its back and pulling the new span. Modernization of the casing consists in fitting under the desired size.
The cardan shaft and the rear axle are suitable from any car, you don't need to change anything in it.
How to install a wheelbase with your own hands?
Here the main thing is to choose the correct diameter of the wheels. For a mini-tractor with a turning point, it can be taken from a passenger car if the diameter of the disks of at least 14 inches. Too small wheels will be linked to the ground, and with large - it is difficult to manage technician. It is possible to facilitate the use of the tractor by installing the hydraulic system. It is completely removed from any decomposed agricultural machinery.
- The front axle is easy to build from the pipe by installing bearings on it. Another option is to take from the other, unnecessary technology.
- Tires need to choose with a deep tread pattern - it increases the tractor maneuverability.
- Good depreciation gives tires by 18 inches.
Rear wheels are installed on the bridge hubs in a simple way: the center of the disk with the mounting holes is cut, and the same part from ZIL-130 is welded to this place.
How to install steering?
To build a mini-tractor with their own hands, any steering, taken from a passenger car suitable. The most successful will be the option with the hydraulic system - it will improve the handling of the tractor.
Also need an oil pump - it starts using the engine. Wheels basically best connect through a gearbox.
An important element of the system is a drum hydromechanical brake. It connects with a pedal.
After all parts of the design are collected, the operator's workplace is issued. To do this, the seat adjustment seat is installed. You can build a canopy with your own hands, consolidating it on 4 welded racks.
To ensure safety, the engine and all internal elements are hiding under the steel casing - it is usually fused from the galvanized steel sheet. To work in the dark, the tractor is equipped with a headlamp and a battery for it.
To assemble a self-made minitractor filling 4x4, it will be necessary to compile a scheme, study the structural features of the technique. The need for such an aggregate occurs when it is necessary to treat land, plant or remove the harvest.
Step-by-step instruction
The classic of agricultural machinery is made with their own hands using a welding machine, disk plate, drill. The assembly of the mechanism begins with the manufacture of the frame. It consists of a spar, front and rear traverse. The spar is made from the ranger of 10 sizes or the square shape tube 80x80 mm. On the traverse you need to use 16 size. Any engine will suit the 4x4 minitractor. The most suitable option is 40 hp The grip will be required from GAZ 52, and the gearbox is from GAZ -53.
To connect the basket and power unit, you need to make a new flywheel. The bridge applies any size and is inserted into the mechanism. Cardan shaft make up from different cars. In the homemade tractor 4x4 bridge in the front constructs independently. For good depreciation, tires are 18 inches. There are 14 inches discs on the front axle. If the wheels are smaller, the 4x4 minitractor will fall into the ground. Otherwise, the technique will be hardly managed.
To reduce the load on the chassis, use tires with good soils.
During the manufacture of a mini-tractor for a household, you must use the main transmission cardan with trucks.
In all minitractors 4x4, the fracture is installed with their own hands the gearbox closer to the driver and fixes on the frame. For pedal control homemade, it is recommended to put a hydraulic drum brake. And the rack of the steering wheel, and the pedal control fractures are suitable from the VAZ machine.
Assembling machinery
The components of the tractor are fastened with bolts or welding. Sometimes possible combined fastening of parts. It is important to position the seat dismantled from the passenger car. The next stage of assembly of equipment is the installation of a power unit. To touch the motor on the frame to well, you need to use a special plate with grooves. Then it will be necessary to pave an electrical and mechanical control system. So that such work was performed qualitatively, the electrical system of factory mini tractors is studied. Next, cubs, taking into account their wishes.
The next step is to arrange the body and its combination with the engine unit. A small trailer from the passenger car can serve the body. If the whole process of breaking is short, we get a simple algorithm: the motoblock is located on the frame, the braking system of the drum type and the steering rack from Zhiguli is installed.
Motoblock take any. If we take the motoblock "Neva", it is more expedient to choose with the hitch. Then the mini tractor will carry loads and trailers. Another suitable motoblock is a Diesel Block "Centaur". To determine which motoblock to choose, you need to deal with the target destination of the mini-tractor. The tractor with a broken frame 4x 4 has a basic advantage - maneuverability.
Conclusion on the topic
If necessary, you can make a haymaker, cutter, bucket. The main advantage of the tractor with a broken frame is maneuverability. Its assembly is simple, so such an agricultural unit can make any dachane, which disassembles the technique. The cost of the self-made car will be relatively lower than the price of the Pskov factory analogue.
MT 244 Caliber Minitractor can be operated in all conditions and full off-road. A pneumatic suspension consists of a receiver, an updated TC control valve, compressor. The MT 244 minitractor can be stored in the garage, and due to the presence of enhanced attachment equipment, a slight fixation of various devices is provided.
Rural life implies a large number of works characteristic of this type of terrain. Honor of manual labor nobody disputes, but the use of small mechanization means, in this case, can only be welcomed. However, not all categories of citizens have the opportunity to purchase a finished all-wheel drive minitractor in a special store, because the price of even the "cheap" model can be at least 50 thousand rubles.

The all-wheel drive minitractor, made by his own hands, has a fairly good characteristics of passability, which gives it the opportunity to actually actually be the same front of work as the store analogues, such as Uralets, Cubot, Bulat 120, Janmar, Belarus 132n, scout.
Agricultural work on the garden, in the garden can deliver joy to people. But before you enjoy the result, you will have to make a lot of effort. Self-made miniature tractors help to improve their lives and improve the productivity of work.
Design features and sizes
Of course, this technique can be bought in the store. But expenses in this case are often excessively high. And what is the most offensive, for the largest land, where powerful cars are required, the purchase costs grow sharply. In addition, for those interested, the training of the all-wheel drive mini-tractor 4x4 in itself will be enjoyable.
But it must be borne in mind that when independent work will have to thoroughly think over all the nuances. There is no point in making the design worse than the factory models.
First, determine which it is necessary to perform on the plot. Then the right attachment equipment is selected, the optimal placement and methods of attaching it are determined. It is customary to share homemade mini tractors for the same parts as their "store" analogues:
- frame (most significant item);
- drivers;
- power point;
- Gearbox and gear node;
- steering block;
- auxiliary (but no less important) details - clutch, driver's seat, roof and so on.
As you can see, most of the parts from which homemade mini tractors are harvested in the finished form from other techniques. You can use both the basis and cars, and other agricultural machines. But the number of permissible combinations of components is not so great. Therefore, it makes sense to navigate the ready-made combinations of parts. As for the sizes, they are chosen at their discretion, but as soon as these parameters are fixed in the drawing, it becomes extremely inconsistent with them.
Most experts believe that it is best to use designs with a rejuve frame. Yes, experienced masters prefer such an option. Based on the motoblocks.
Despite the seeming bulky, these mini tractors are quite effective and work very well. The main thing is that each component is put on its strictly reserved place.
Tools and materials
The frames are often prepared from traverses and spars. The spars themselves are made of chalkers and steel pipes. Similarly, the crossmen are made. In this regard, the preparation of any mini-tractor differs little. As for the motors, any versions are suitable that are quite powerful.
But still professionals believe that the optimal option is the four-stroke diesel engine cooled by water.They save fuel, and more stable in work. PPCs and dispensing boxes, as well as clutches are often taken from domestic cargo vehicles. But it must be borne in mind that individual components will have to be customized to each other. For this purpose you will have to use a home lathe or access to professionals.
Bridges are taken with old engine equipment almost unchanged. Sometimes only shorter them. It uses metalworking equipment. Wheels are sometimes removed from passenger cars, however, their diameter should be at least 14 inches (for the front axle).
By installing smaller proposals, farmers will often face a mini-tractor immersion in the ground. If you put too much running part, maneuverability will worsen. Partially compensate this drawback helps hydraulic steering power steering. Shoot it from old cars, or do it yourself - to solve only the master. As for the driver's seat, this is, although an optional, but very important item.
If the basis take the old fiberboard, then you can take in the finished form:
- motor;
- clutch system;
- wheels and semi-axles.
But the frame from the motoblock can be only an integral part of the mini-tractor frame. Using it, it is necessary to watch that the mounts for the motor and gearbox are ready. If a motor-cultivator is taken as the basis, it is refused from a powerful frame, quite enough of a square section of 10 cm. Preference in square form is given because homemade mini tractors are often driving in bad roads. The magnitude of the frame is selected in accordance with the size of other parts and their severity.
The simple type of transmission implies the use of belt clutch that puts on the gearbox. In a more complex embodiment, the torque is transmitted using cardan shafts. The choice, however, does not have a consumer - it all depends on the features of the motor and from the wheel formula. If an efficient rejuvenating frame is used, then in any case, you will have to put cardan shafts. It should be borne in mind that with independent production it is difficult.
The control is created according to the standard scheme, just take the items from any car. Since the load on the steering wheel during the operation of the mini-tractor is less than that of the passenger car, you can safely install the parts used. Fastening the column, tips and other components occurs just as on the car. But the steering thrust shortens a little so that they fit the narrowed rut. For work, thus you will need:
- screwdrivers;
- spanners;
- roulettes;
- welders;
- hardware.
How to make your own hands?
Homemade mini tractor felt is a kind of classic in such a technique. Therefore, it is worth starting a review from it. There are 3 different options, how to implement a similar scheme:
- use the fiberboard and put the factory frame on it;
- collect the product completely from spare parts;
- take the fiberboard and supplement it with spare parts from a remake set.
It is extremely important before starting work to prepare drawings. In the absence of experience and technical drawing, it is better to turn to professionals. Ready-made schemes distributed via the Internet cannot guarantee an always optimal result. And their publishes are responsible, the more the owners of the sites do not bear. Between parts of the frame, it is necessary to provide a hinged bundle.
The engine put in most cases in front. For the manufacture of the frame, the channel is used usually from 9 to 16. Only occasionally uses Schweller No. 5, however, it will have to be strengthened with the help of transverse beams.
Cardans are often used as a hinge binder assembly on a mini-tractor with a breaking frame. They are removed from GAZ-52 or from GAZ-53.
Exchanges are recommended to put four-stroke motors on the homemade technique. Power 40 l. from. It is enough to solve the majority of economic tasks. Often engines are taken from Moskvich and "Zhiguli" cars. But it is necessary to pay attention to the gear ratios. It is also required to take care of efficient cooling. Insufficiently well-cooled engines will lose power, and their parts are rapidly wear out. To make a transmission, it is advisable to use removed from trucks:
- power removal shaft;
- gearbox;
- clutch system.
But in the finished form, all these parts for a mini tractor will not fit. They will be needed to improve. The grip and the motor will be qualitatively connected only with the help of a new basket. The rear segment of the flywheel will have to shorten on the machine. In the middle of this node it is necessary to break a new hole, otherwise the fracture node will not work normally. Front bridges in finished form take from other machines. The invasion of their device is not recommended. However, the rear bridges should be improved slightly. Modernization consists in shortening the semi-axes. The attachment of the rear axles to the frame is made using 4 stepladers.
The magnitude of the wheels on the mini-tractor used only for the movement of goods must be 13-16 inches. But when it is planned to perform a wide range of agricultural work, you need to use drivers with a radius of 18-24 inches. When it is possible to create only an excessively large wheel base, you need to use hydraulic steering steels. Hydraulic cylinder - a device that cannot be done with your own hands. The only opportunity to get this item is removed from unnecessary technology.
In order for the working pressure to be maintained at the desired level and circulated a sufficient amount of oil, you will have to put a gear pump.
It is important in the manufacture of a fracture to bind a gearbox with wheels planted on the main shaft. Then it will be much easier to manage them.
Seat for the operator take from passenger cars, it is not necessary to redo it. The steering wheel put so as not to rest on his knees.
By installing control systems, you need to follow to be free access to all of them. A high-quality fracture, even if it is assembled from old spare parts, it should per minute to produce up to 3000 engine revolutions. The smallest permissible speed is 3 km / h. If these parameters are not provided, you will have to redo the mini-tractor after the test run. If necessary, regulate the transmission.
Experts note that all the leading wheels are able to have separate gearboxes and hydraulic distributors of 4 sections if possible. Such a solution allows when assembling to refuse to install Cardanov and from the use of differentials in the rear bridges. You can load the mini-tractor only after successful running. In many cases, miniature tractors make components "Niva". At the same time sequentially:
- collected frame;
- put the engine;
- mounted transmission;
- steering steering column;
- fasten the hydraulic components and wheels;
- equip the brake system;
- put the seat and cargo body.
A classic approach to the arrangement of the frame based on "VAZ 2121" implies a whole-wardrobe design.Make it relatively simple. However, the maneuverability of such a system is small, which is especially felt when the mini tractor turns either rising in rough terrain with a cargo in the body. Therefore, the increased complexity of the assembly of the fracture is quite justified by a large cross-country and a reduction in the rotary radius.
Scrolls perform the role of ribs stiffness. Longitudinal spars are set in such a way that the hard steel box is formed. It is necessary to provide brackets, fasteners, without which the body will shift unpredictably. A couple of seats are welded. The detail of 0.6x0.36 m is put at the back, and in front of 0.9x0.36 m. Based on the eighth sized channel. A pair of pipe segments add to the frontal semiramp. These segments will allow you to install the motor. The back half of the metal is rack from a thickness of 0.012 m. To enhance it, an equilateral corner is used.
