Having a cottage plot or garden, it is impossible to do without a good mechanical device, which will help to accomplish the soil for landing all kinds of agricultural crops. However, to acquire such an aggregate, it will be necessary to post a small amount of money, however, there is an alternative, which will allow you to get the necessary device and save your finances at the same time. The homemade minitractor with a breaking frame is quite realistic to make it yourself.
The homemade minitractor fracture 4x4 is similar to the usual tractor built on the basis of the motoblock. Conditionally, tractors can be divided into three varieties: homemade, factory, converted by factory parts.
Independently made minitractor
The minitractor is not so easy to build, however, it is quite interesting that requires attention and zeal. Today, you can find a lot of various assembly options, however, there is the most suitable design that is suitable for both experienced designers and newcomers. First of all, you will get acquainted with the frame design. Despite the angularity from the outside, all connecting angles and chassis parts are distributed proportionally.
Drawings of a minitractor with a broken frame
Key details of the frame:
Spars;
Traverse.
Spars have a three-stage assembled structure. The front steps are made of tenth-size chambers, and the latter is the square of the square shape. The rear traverse is made from the sixteenth chaserler, and the front is the twelfth. Absolutely such a concept will be appropriate for cross. The tractor can be equipped with any motor that will correspond to the power unit. Most suitable option It is a 4-cylinder engine with water cooling on a diesel. Optimal power homemade minitractordesigned to work at home sectors - 40 hp
To dock the clutch basket with the power apparatus, it is necessary to build on a new engine flywheel and make a renovated basket casing to fit it to the desired size. The flywheel is usually processed using a lathe. It is necessary to cut the rear section and sharpen another hole in the middle. The bridge does not need significant amendments, so it is suitable for any size. 4 launches are used to mount to the frame. To create a cardan shaft fit parts from any machines. In order to achieve a high level of depreciation, it is recommended to install 18-inch tires. Install the wheels are easy enough and simple. It is worth paying attention to that from the disk it is necessary to cut a small part in the middle with a hole for installation. After that, instead, a central disc from ZIL-130 should be welded. The bridge in front can be constructed independently, since it is not necessary to have special abilities for this. However, if you want to make the assembly procedure simpler, you can simply use the bridge from another car.

Tractor wheelbase design
It is this component of a mini tractor to pay special attention. Of course, you can take advantage of ordinary wheels from a car, but here you need to go slowly. Required wheel disk sizes for front Bridge, make up about 14 inches. If you set the wheels with a smaller diameter, there is a high probability that in the future the tractor will not work correctly. And for us the main task is that the minitractor does not fall into the soil. But there is another aspect that should also be considered. In the event that the front wheels are unnecessarily large, the driver will be quite difficult to control this unit. However, this process can be facilitated by installing the power steering hydraulic power.
In addition, it is important that the tires of the wheels had high-quality soils. This will make the minitractor more maneuverable, will reduce the load on the running part, as well as simplify the operation of the device.
Steering
In order to improve the tractor maneuverability, it is advisable to put hydraulic control. Hydraulics really find a decomposed agricultural machinery. It requires an oil pump for its assembly to work with the engine. Thanks to it, it is supported by the required level of pressure in the hydraulic motors. It is best if the control of the wheels of the main shaft is carried out using a gearbox.

Suspension
The direction of turnover is committed due to the simple distribution of 4 work positions. The main advantage of the all-wheel drive minitractor with 4x4 frame is that it has excellent maneuverability. Undoubtedly, it makes the assembly more difficult, since it is necessary to construct a reliable and correct shaft with connections. For the facility homemade tractor It is recommended to use cardans of the main transfer from trucks. Today you can find a lot of video materials with detailed instructions For the manufacture of minitractors with their own hands, however, as a rule, the main rules of manufacture coincide. In all tractors, the gearbox is fixed on the frame, the steering thrust contributes to the control. As a rule, a hydromechanical drum brake is used everywhere, which is controlled by pedal. Accelerator and mounted equipment is used by manual control.
The design of a minitractor requires various spare parts, which are superbly fit automotive. Thus, the drum brake is useful for the front wheelbase. Rake steering wheel and pedals management can be taken from a small vase.
Tools for design
In addition to the details, a wide range of various tools should be applied:
Welding machine;
Spanners;
Disk stove and so on.
In some cases, it may be necessary to turn to professional welders or services in the car repair. However, it is important to objectively assess our own abilities and skills in this industry. Device control and installation of a driver's seat as a rule, the installation of the control system and the kinematic circuit is carried out after constructing the chassis. One of the most important factors In this case, it is correct to place the driver's seat. It is recommended to install a seat from any passenger car, which is not at all difficult to find in the automotive services. Also important is the position of the steering wheel, it must be attached at the most convenient level for the driver. The steering wheel should not make his knees, in connection with this, it is necessary to mounte so that the driver does not have a feeling of discomfort during the control of the aggregate.
Motor and Equipment Body Minitractor
As soon as chassis The devices will be designed, the kinematic plan has been implemented and the seat is installed, it is time to start installing the main element of the unit - the engine. For its high-quality fixation on the frame, a special slab with grooves should be applied. In addition, it will allow the required level of stiffness of the tractor's chassis. After that, it is necessary to mount the electrical and mechanical circuits of the control system. The body's casing may be any, depending on the desire of the manufacturer. However, some nodes and components of the body are recommended to hide to prevent contamination and breakage, due to the contact with the soil.
Methods of assembly
Before creating with your own hands this mahuine, it is necessary to highlight the main objectives for which this device will be destroyed. The product procedure itself can be painted quite simple: the motoblock is installed on a homemade frame. The brake system should be drum, and the steering rail can be removed from the Russian Zhiguli.
If the "Neva" motoblock is used as a base, it is better to choose with a hitch, as it will allow transporting trailers. Of course, if you use the profile motor-block, the service life of such a car, and its performance will significantly increase. Made by their hands the minitractor 4x4 fracture will become an indispensable Assistant to work in the country areas or rural gods. In addition, its price will differ significantly from the minitractor, which can be bought in specialized outlets.

How to make tractor classic 4x4 with their own hands
The homemade tractor can be made from spare parts, which lie in the garage. Perhaps the owner has long been going to throw something, but most will help in the design of a mini-tractor. The classic is a homemade tractor equipped with a fracture frame.
Full-wheel drive mini-tractor, designed own handsmay have good technical characteristics. This will give the tractor almost nothing to yield to the analogues presented in specialized stores, even though the power of the self-made tractor will be less. In practice, the capacities difference is practically not noticeable.
The classic mini tractor is used in agricultural work, including:
- plowing the household plots to prepare for further work;
- cultivation of soil, removal of weeds;
- harrowing soil;
- sowing on pre-prepared soil;
- landing and digging potatoes.
The application of the self-made unit can be wider if it is possible to provide in advance when designing it. If you don't miss anything, it will be possible to use for the transport of goods, cleaning snow and haircuts of lawns and lungs. It can be used at the billet of the hay for livestock.
Thus, the 4x4 classic can greatly improve the life of an agricultural worker and a resident of the country house, since with the help of such equipment you can perform absolutely any work.
Consider the design instructions. The most important part of the manufacture of a self-made unit is a drawing. The correctly compiled scheme will allow to successfully construct the unit. With such an assembly it is important to understand that some details will have to be customized under the features of the motor and frame, because components, as a rule, are taken from different techniques, from here and incisions in size. The fitting of the parts is carried out on the lathe.
After drawing up the drawing, you can proceed directly to the assembly, which involves several steps. The frame is collected from traverse and spars with a three-stage structure. 1 step - Sweller number 10, the last one is steel square trumpet 80x80.
Traverse rear is made from Schawler №16, front traverse - from Schawler number 12.
If the mini-tractor is constructed on the basis of a motoblock, the engine located on it will perform the role power aggregate. If the unit is collected in another way, the motor will have to be purchased separately. Any unit working on diesel fuel, with a capacity of more than 12 hp Optimal option - Motor by 40 hp with water cooling function.
Transmission, power take-off shaft, clutch can be "borrowed" in GAZ-53 or GAZ-52.
Details will have to be finalized - construct motor flywheel, removing the back of the back and make a hole in the middle.
The bridge can be installed as it is, without making anything. It is fixed to the frame with the help of four stepladder.
Wheels are suitable from any passenger cars, optimal diameter 18 inches.
It has four-wheel drive and a fracture type frame frame. The author produced work in its free time, using forum materials and their own skills. The all-terrain schedule was based on the reliability of the designs, but not forgetting the comfort of the driver and passengers. The main purpose of the uses are rides on forest trails for hunting, fishing or gathering of supplies, so all-terrain vehicle has a greater capacity and load capacity.
Materials and details that needed to create this all-wheel drive:
1) Engine internal combustion From the car
2) Safari Variator
3) Transmission gearbox from an eye.
4) pump dispenser
5) OI-25 tires lightweight.
6) profile pipe
Consider in more detail the stages of the construction of the all-terrain vehicle, as well as its main construction nodes.
The frame of the all-terrain vehicle was reinforced with the structures from the profile pipe.
The back of the all-terrain vehicle was created:
discs and dressed Tires OI-256
Then the author began to make bridges of all-terrain vehicles:
Other work on the transmissions of the all-pass:
The case for the cabin car was taken for the cabin car:
Unloading wheels and basic parts for assembly:
This is how the steering is performed:
WORKING CABIN WORK WORKS:
And trailer connections:
The all-terrain vehicle is able to develop a speed of about 35 kilometers per hour and this is not the limit, there is enough power, but control at such a speed becomes very uncomfortable. But as is known for all pass maximum speed It is not so important, since the main routes will be held on the first and second gears at a speed of up to 15 kilometers per hour.
The car's length turned out about four meters of twenty centimeters. The height of the all-pass is equal to two and a half meters. The total mass of the machine is about 700-800 kilograms, but will still grow, since the author has provided a few mandatory upgrades for this all-terrain vehicle.
The speed of about 35 km / h was measured by GPS, then scary.
On the gearbox, the differential was welded before installing the all-terrain vehicle, since the differential in this transmission design scheme does not require.
A few more photos of work on the elements of the construction of all-pass designs:
As can be seen from the photos on the all-terrain, the front axle is not fascinated, in particular because of the massive cabin and the absence of Kung as such, in the future, instead of the trailer, the author plans to make Kung, and more precisely to finish directly on it with the help of a frame of a profile pipe and metal sheets or plywood .
It is also planned to finish the boats so that the all-terrain vehicle can force water obstacles.
Initially, the author planned to install the KRAZ Wheels, as they are better suited for all the mass of such a mass. Yet OI-25 are not enough for such weight, moreover, a large width of the wheels is needed, since the center of severity of the all-terrain vehicle is quite high and there is a probability of overturning. That is why the author in the future intends to set the tires of the KRAZ and make a safety arc. When it starts working on Kunga frame.
But with the replacement of tires, it will have to change and disks, as they were made specially under the OI-25 and have a width of 450 mm.
