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,.
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.
The mini-tractor with a complete drive, designed by his own hands, can 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.
See » Overview of the powerful tractor MTZ Belarus-3022 and its modifications
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 No. 10, the last is the steel square pipe 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 of a power unit. If the unit is collected in another way, the motor will have to be purchased separately. Any unit operating on diesel fuel is suitable, with a capacity of more than 12 hp The optimal option is a motor at 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, the optimal diameter of 18 inches.
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. The most suitable option is the 4-cylinder engine with water cooling on the diesel. The optimal power of the homemade minitractor, designed to work at home sections - 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 easy. 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. The required dimensions of the wheels of wheels, for the front axle, are 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.

Brake system
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 construction of a self-made 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 your own hands, however, as a rule, the basic 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 different 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 matter is to accurately 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 the chassis of the device is designed, the kinematic plan has been implemented and the seat is installed, it is time to install 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 you to transport trailers. Of course, if you use the profile motor-block, the service life of such a car, and its performance will significantly increase. 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.

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 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.
