Do-it-yourself homemade mini tractors review. Do-it-yourself mini tractor: how to make, the best homemade options

08.03.2020

The agricultural sector includes a large number of works, but the main one, all the same, is the processing of land holdings. This is not surprising, because the ripening of the future harvest directly depends on how well the land is plowed and fertilized.

A minitractor does an excellent job with this set of works - a technical unit that has fairly compact dimensions, while being distinguished by a fairly high power. These units are used everywhere - both in the private sector, and in large farms and agro-industrial complexes.

If in the latter, they mainly use various models from Russian or foreign companies, then at the household level, most often, there are mini tractors made from improvised means. Of course, certain skills are needed for the assembly of a home-made mini tractor to be successful, because this is a rather difficult task.

However, given the fact that manufacturing costs will be much lower than for buying a store version, many are already thinking about designing a mini tractor on their own.

Application areas of the minitractor

Depending on what will be taken as the basis for the future, there are several varieties of such devices, as well as the types of work that they are able to perform:

If a sufficiently powerful engine is taken (for example, from an old Zhiguli), then such a unit can carry out almost the entire range of work characteristic of rural areas. We are talking about plowing land, hilling, ridding the soil of weeds, forming beds, planting potatoes with the help, etc. Pictured is the engine:

If additional equipment is provided for them, then such devices can mow grass for hay, clear snow (see) and sweep sidewalks. Such mini tractors are capable of processing an area with an area of at least 6 hectares.
The second type of homemade mini tractors is made on the basis of a relatively powerful engine (see), which is identical to the power of a walk-behind tractor (even). Such units are capable of processing an area of 2 hectares, carrying out almost the same list of works.
The only thing is that the power of a home-made mini tractor is not enough for plowing complex plots of land and transporting large loads.
The last type of homemade mini tractors is a device for irrigating pre-treated soil with various fertilizers, as well as spraying pesticides.

As we can see, the efficiency of homemade mini tractors in operation is quite different, depending on the power output of the engine used.

In principle, in terms of scope, a home-made version is practically no different from a store-bought one.

Like him, the main concern for such a unit is work on the land, where the plowing and cultivation of the soil is carried out.

Before you start using a chainsaw, be sure to familiarize yourself with the features of setting up and adjusting Husqvarna brand chainsaws in

If a breakdown occurs, then you can find out about the causes of malfunctions and how to fix them.

Advantages and disadvantages of the unit

Of course, the performance of a branded mini tractor is much higher than that of home-made counterparts. But no one tried to prove that home-made units are comparable in their technical data with purchased options.

Initially, it was assumed that do-it-yourself mini-tractors would be used in fairly small areas, where their working power would be sufficient. That is why the use of home-made units at the household level is becoming more and more appropriate.

Other advantages of such mini tractors include:

Pretty good indicators of the quality of plowing land. At the same time, they are in many ways comparable to the penetration depth shown by mini tractors purchased in stores.
A fairly simple operation of such devices does not require special knowledge and skills.
Making a homemade unit will be a much cheaper option than buying a new mini tractor.
A more simplified repair, because you yourself make a mini tractor from available parts, which you can then easily get.
The ability to make changes to the device configuration, adding something new. In purchased mini tractors, this is unacceptable, because you can completely disable the unit.

However, do not think that making a mini tractor at home is an unconditionally profitable enterprise. This method also has its drawbacks:

A rather painstaking assembly process, because it requires certain technical knowledge, as well as the ability to work with a welding machine, etc. In other words, making a mini tractor with your own hands is not suitable for everyone.
Finding the right spare parts and parts is also an additional difficulty in this matter.

As we can see, there are still more advantages, which indicates the right decision to make home-made mini tractors with your own hands. Probably the main advantage is good cost savings, because the issue of price has become decisive in recent times.

Features at work

When performing various work on a home-made mini tractor, it is important to understand the fact that this is an amateur-level unit, so you should not set very difficult tasks for it.

Of great importance is the engine that you use in the design. Often, this is no longer a new motor, taken from an old car, or purchased “from hand”. Such engines, in general, do not have internal regulation of the number of revolutions at different loads.

Therefore, sometimes you have to release the gas pedal so that the engine does not overheat from effort.

release the clutch;
press the gas pedal to the stop;
turn the starter for 7-10 seconds, after which the engine should start.

By doing such simple manipulations, you can ensure that the engine will start without any problems during the day. It is also worth remembering that in winter, fuel consumption increases by almost 30%. This fact must be borne in mind when planning long-term work in the cold, for example, when taking firewood out of the forest.

It is best to stock up on an extra canister than to get stuck among the snowdrifts, away from people.

DIY assembly examples

The assembly of a homemade mini tractor can be carried out in different ways, so there is no specific methodology, as well as parameters that must be strictly followed.

No, building a mini tractor with your own hands is a fairly free activity where you can connect your imagination and your own developments.

However, it will not be superfluous to describe a couple of ways to make the picture more clear.

In general, the procedure is approximately the following:

At the initial stage, the frame of the future homemade mini tractor is being designed. Weld it from a metal channel. As a rule, they take number 5 or number 9. Two semi-frames are made from this material, which are interconnected by cardan shafts used in heavy vehicles.
The design can also be made from a solid frame. To do this, you need to take two spars (right and left side of the frame), as well as two traverses (rear and front of the frame). In this case, channel number 10 will be used for the manufacture of spars, and numbers 12 and 16 for the manufacture of traverses.
A metal rod is installed across.
Next, the engine is installed on the frame. The choice of the motor lies entirely with the person who conceived the self-assembly of the unit. Often, UD-2, MT-9 engines, etc. are used for these purposes. You can also take the engine from an ordinary Soviet-made motorcycle.
The gearbox must be placed on the frame so that it is turned towards the person driving the minitractor. By the way, a box taken from an old GAZ-53 is perfect for these purposes.
As a steering wheel, you can use the steering installed on older cars.
A tow bar must be welded to the rear of the frame, which will allow you to attach additional attachments.

Wheels need to be selected depending on the type of work that you want to perform on a homemade unit. For plowing soil, wheel sizes must be at least 24 inches in diameter. For normal transportation of goods, 15 inches is enough.

At the final stage, all working units are adjusted, belts are tensioned, etc. Of course, the instructions are rather sketchy, but on the net you can find the latest video for free, where various craftsmen make mini tractors with their own hands, giving accurate advice, as well as the whole process clearly.

For more information about a homemade mini tractor, see the video:

Manufacturing deserves special mention. At the same time, there is no fundamental difference which unit to use, because their design is almost identical. Consider the approximate algorithm of our actions:

We will also start with the manufacture of the frame. At the same time, we only supplement that part of the structure that will be located above the second pair of wheels, because the front part will be our walk-behind tractor.
There are no strict recommendations on the diameter of the metal pipes used to make the frame. All component parts are cut with a grinder, and then welded together, forming the back of the frame. In the middle, you can add an additional metal beam to make the structure more reliable.
A towbar is welded on the back, which provides work with a trailer and other attachments.

Hubs are available for the front wheels. They will be attached to a metal pipe, suitable in width to the front of the minitractor.
In the center, you need to drill a through-type hole through which the fastening to the frame is carried out. A worm-type gearbox, in this case, will connect the rod from the steering wheel and the frame.
Next, you need to install the rear axle. This is done on bearings that are installed in the bushings. Next, a pulley is installed that provides the supply of work from the motor used.
Wheels can be picked up from old cars, or from the same walk-behind tractors.
At the final stage, the brake system is installed, as well as the adjustment of all working units.

It is worth remembering that if this home-made device enters the roadway, you may be stopped by traffic inspectors to check if you have the right to drive this vehicle.

Therefore, if you plan to drive a homemade mini tractor onto the roadway, you need to take care of obtaining a driver's license from the traffic police.

Conclusion

Homemade mini tractors are a rather interesting structure. At the same time, it is simply unrealistic to meet two identical units, because during the assembly process, each adds something of its own.

Indeed, for a man, the very fact that he does something with his own hands is already a kind of hobby, the satisfaction from the results of which is much stronger than from simply buying a finished mini tractor or other agricultural unit.

A mini tractor for a small farm is, if not necessary, then a very useful technique. The unit mechanizes plowing, harrowing, cultivating the land, removes and takes the crop from the field, and helps in forage harvesting. The capabilities of the device are expanded by additional equipment.

There are enough proposals for mini-equipment on the agricultural machinery market, but the prices of the simplest and least functional Chinese-made machine start at 120 thousand rubles. A home craftsman can significantly reduce costs by making a mini-unit, equipment for it with his own hands.

Choosing the parameters of the future car

Consider on what factors and parameters the stability of the minitractor depends.

Power point

The master needs to clearly decide what you want to do with a home-made unit and in what area. The power of the power plant will largely depend on this. The experience accumulated by specialists allows us to recommend:

engine installation 4-7 hp with the area of the cultivated area up to 20 acres;
9-17 HP up to 50 acres;
20-40 HP up to 4 ha.

For the operation of additional equipment, the engine must be equipped with a power take-off shaft.

Chassis, steering and transmission

Most home-made units have a frame structure on two axles with pneumatic wheels. The drive can be on one or both axles. It is advisable to use a mechanical type transmission with a gearbox, clutch assembly, cardan shafts and axles from a light car or agricultural machinery.

In the same way, steering components, brake systems, and electrical equipment are selected.

Having sufficient capacity of the hydraulic pump, hydraulic motors, distribution devices and power hydraulic cylinders, it is realistic to equip the unit with a full volumetric hydraulic drive, which will make it possible to abandon mechanical transmissions and simplify the steering scheme.

Such a solution will greatly facilitate the creation of a machine with a breaking frame - two half-frames are connected by a power hinge assembly, which increases the maneuverability and maneuverability of the minitractor, provides copying of ground irregularities by the axle wheels.

The use of a caterpillar type mover significantly complicates the design, it will require the presence of light links of the caterpillar belt, the development of power moment transmission units for each of the belts with different parameters (for turning and turning), and the installation of caterpillar belt tensioning mechanisms.

Examples of developments by homemade masters

Let's turn to the well-known home-made mini tractors, which received worthy reviews in the world of agricultural machinery of their own manufacture.

Making a clutch for a mini tractor

The clutch basket casing is connected to the motor through an adapter with coaxial mounting holes. The device itself was used from GAZ-51, the mechanism is turned off by a hydraulic drive.

Mini tractor features:

components and parts are used from used cars and agricultural machinery;
a breaking-type frame is assembled from two half-frames and a crosspiece from a MAZ truck. Provides high cross-country ability and maneuverability of the machine, copying the terrain with pneumatic wheels, directional control;
a cardan shaft with a pair of end crosses, transmits the power moment from the box to the bridge, regardless of the “kink” of the frame;
a drum-type service brake is mounted on the box shaft;
the drive axle is used from an electric car, rigidly fixed to the semi-frame;
front axle suspension independent. Shock absorbers, springs, levers are used from ZAZ;
the machine can be converted into tracked and all-wheel drive versions.

The Volchok unit is converted into an all-wheel drive mini tractor with your own hands in the following order:

Behind the gearbox, a transfer case from the GAZ-69 is installed through the intermediate cardan shaft, which transmits the power moment to the drive axles, the presence of a reduction gear in the device allows, if necessary, to increase the traction force.
A bridge is mounted on the front half-frame - an analogue of the rear axle of a minitractor.
The main gear of the front axle is connected to the transfer case through a cardan drive.

Alteration of the "Volchka" into a caterpillar minitractor with your own hands:

Build a caterpillar type propeller. For this purpose, a large diameter tire with cut sides is used. We use solid rubber wheels from transport carts as rollers.
We fix the semi-frames rigidly relative to each other (the power hinge does not work).
We dismantle the front suspension, on the front half-frame we fasten the roller units with the track tension mechanism.
We dismantle the rear axle, in its place we install a shortened axle from the GAZ-21 with the main gear and differential, we connect the hydraulic control of the drum brakes separately for each side. We install rollers in place of the rims.
Two drum brake pedals on the rear axle, through the operation of the differential, provide a change in direction.
We dress and pull the caterpillar tape.

Optional equipment

Having made a trailer with your own hands, you will significantly expand the functionality of a mini tractor, minimizing financial costs.

We start manufacturing with a supporting frame - welding of round or rectangular pipes (at least 40 mm in cross section) of the product frame. The axle of the wheelset is made of a steel rod with a diameter of 35 mm. The axle is connected to the carrier frame by a longitudinal hinge, side spars and corner supports.

The body box is made of edged planed boards connected with screws and metal corners.

To attach the product to the minitractor, an articulated drawbar is used, inserted into the tubular body. The coupling with the vehicle is fixed by a chain-type fuse.

Do-it-yourself minitractor

If you have a house in the country, and even more so if you live there permanently, you know what real housework is. It is simply impossible to do without transport when running a household. The best for these purposes is a mini-tractor, with its help it is possible to ensure the fulfillment of all needs, from digging the land for sowing, to transporting large and small loads. But such equipment is far from cheap, what to do? There is one option - to make a mini tractor with your own hands. Yes, the task is not easy, but if you do it, you will save a lot of money, and the satisfaction from the finished machine will come every time you start working with the tractor.

Which version of a homemade mini tractor to choose

Homemade mini tractor for the household with a broken frame

The best option for a homemade mini tractor is a machine with a broken frame. Such a unit consists of 2 parts, rear and front, the coupling of which is carried out by a special hinge mechanism. In the front are all control mechanisms, as well as the entire chassis. Management is carried out by means of a steering wheel and hydraulic cylinders, the whole structure is bent on a hinge and changes the relative position of the two parts of the tractor. Thus, if you use this design, you can save on some of the parts designed to mount the control mechanisms, which under normal conditions are located at the rear of the machine.

The rear of such a mini tractor is much simpler in design than the front. It consists of a rear axle, which is fixed in cradles on the side members of the axle shaft, a driver's seat is installed on this design, and a device for attaching attachments from the Belorus tractor. The differential and axle shafts can be taken from any loader. Rear suspension can be done, but this is not very advisable, usually depreciation is achieved due to low pressure in the wheels.

In addition to the simplest design, such a mini tractor has several advantages:

Large production capacity, this machine is capable of delivering power close to a large tractor, especially when assembled as a four-wheel drive tractor with an articulated frame;
The ability to turn around in minimal areas, the turning radius of this device is minimal due to the broken frame design. The tractor can be rotated 360 degrees in almost one place, this is a particularly useful feature when plowing the land;
Low fuel consumption, and this indicator also depends on the design features of the machine, but most often the consumption is minimal;
Relatively low assembly cost. If you buy such a tractor assembled at the factory, then the amount will make your eyes crawl on your forehead. And if you make it yourself, you can get a significant markdown, since structural elements are used for assembly, which you can get at the lowest prices.

Drawings - the first stage of assembly

Mini tractor drawing
Kinematic diagram of a minitractor

Before taking on the tools, you need to carefully consider the entire design of the tractor itself and the coupling scheme of its two parts. Correct drawings are the basis of the basics. It is best to find reliable drawings from outside sources, since it is very difficult to foresee all the design features, because a tractor is a very complex set of interconnected mechanisms. It is necessary to think over the location of all elements of the system so that they can interact with each other qualitatively. First of all, the main components of the tractor and the driver's seat are applied to the drawing. If you are not particularly experienced with drawing up drawings, you can ask an experienced locksmith to help you with this problem, and then take apart the plan and make a tractor yourself.

The second stage is reading the drawings and assembling the entire structure

When you have found the necessary drawings, you can proceed to search for the necessary components and assemble them into a single system.
Remember, when looking for parts, pay the most attention to three groups of spare parts: engine, chassis and gearbox - they should be removed from the same type of equipment, so there will be no need to fit them to each other.

Choice of engine and transmission

Engine UD-2

In choosing suitable engines for a homemade mini tractor, it does not shine with variety, most often you have to choose from what is and is most suitable. Best of all, in terms of economic and production indicators, 2 types of UD-2 or UD-4 engines are suitable for installation on a tractor of this design, but, in general, diesel engines with one or two cylinders can be used. You can, if you can find it, use the M-67, in its characteristics the main thing is a long service life with minimal maintenance costs.

Before installation, such an engine must be modernized, the gear ratio increases in it, it is also necessary to come up with a cooling system, since it does not have one. For cooling, you can install a fan that is mounted on the crankshaft with a casing connected to direct the air flow.

Sometimes engines from Muscovites or Zhiguli are used as a power plant. At the same time, when the engines are removed from the cars, the gearbox with the transmission goes along with them, remember, so there is no need to fit and look for additional parts.

Wheels are selected based on the purpose for which the vehicle is made. If you plan to use it only for transporting goods, pulling them and other similar work, then you can take discs up to 16 inches. If you plan to use a mini tractor for field work, it is better to take more massive wheels with discs from 18 to 24 inches in order to improve the quality of wheel adhesion to the surface.

Houndstooth frame

The broken frame consists of two semi-frames, the coupling of which is carried out by a hinged joint. To make such a connection, you can use a cardan shaft from a large-sized truck, for example, a GAZ. If we talk specifically about GAZ cars, then it does not matter which model it will be, because in the cardan shafts of any of them there are practically no design features. The frame itself is best made from a channel, so it will be strong enough to perform absolutely any work, and the tractor itself is able to withstand almost any load.

As for the finishing of the tractor, it can be made from a profile of any characteristics. Since strength, for example, for wings is not the most important indicator.

Some installation features

The control system in tractors of this type must be equipped with hydraulic cylinders, this will significantly improve the controllability of the vehicle. You also need to pay attention to the regulation of the gear ratio, it should be set to low speeds. This is done so that the tractor, when performing various work, does not develop too much speed.

The suspension of all tractor wheels is independent and rigid, so that the wheels of any part, rear or front, do not hang when passing difficult sections, it is possible to provide for the possibility of the frame to rotate, 15 degrees is enough. This is done by introducing a UAZ swivel into the breaking system, it is installed in front of the rear half-frame. So that there is no possibility of a larger coup, a limiter is welded on the hinge plate.

The result is a very practical machine that is able to meet all the needs that arise when running a household. All kinds of plowing devices, trailers for transporting goods, mowers and other devices can be easily attached to the tractor.

Everyone can make a mini tractor with their own hands, most importantly, stock up on the necessary tools, material and patience. The result is a full-fledged multifunctional machine that allows you to meet all the economic needs of the owner. High cross-country ability, ease of use, versatility - these are the advantages that you will get after installing a homemade tractor.

Working on a summer cottage or a small farm constantly requires a lot of effort on the part of the owner. Cultivation, hay, garbage, snow removal, delivery and fertilization into the soil. Doing this manually can be overwhelming.

A small tractor can make the task easier. In addition, making a mini tractor with your own hands is as easy as shelling pears if you have experience in working with machinery.

1 Benefits of a homemade mini tractor

It is quite simple to make the main components of a homemade mini tractor with your own hands. In addition, the cost of such a procedure, if the necessary parts are available, is much lower than buying a factory version.

Most often, the units are taken from old (broken) home appliances, and the remaining components are bought in addition. If the farm already has other small-sized equipment, for example, a walk-behind tractor, the task is simplified even more. Therefore, economy is the main advantage.

Also, the advantages of such equipment include the ability to customize the dimensions and combine the nodes on your homemade mini tractor. Standard factory equipment excludes this possibility.

As for the shortcomings, here we can highlight:

the difficulty of developing the correct drawing;
maintained condition of most parts;
problems in the functioning of the machine, in case of lack of skills in manufacturing.

2 What does a homemade mini tractor consist of?

The first thing to do before assembling any equipment is to determine what nodes it consists of. The simplest device of a small-sized tractor includes the following components:

engine (can act as an engine);
a strong power frame on which all other units are mounted;
hydraulic braking system;
assembly with brake discs;
chassis, including wheel axles and wheels (also a suspension or a mechanism that replaces it);
a mechanism for attaching attachments with the possibility of lifting;
steering column;
comfortable chair for the operator;
rear and front lights.

Each of the listed units should be assembled on the basis of a clear general drawing, so as not to disturb the proportions of the machine.

2.1 Which engine to choose?

As a power unit, you can select a variety of options. You can make a small tractor with a zeed engine. A single-cylinder four-stroke engine with a volume of 4.5 liters is quite suitable for cultivating land up to 2-3 hectares. Such an engine was originally designed for homemade cars, is very easy to maintain and can be easily found on the Internet.

If there is an old Cossack available, then the power unit from it is the best fit for a homemade tractor.

A car with a ZAZ engine has a capacity of up to 40-50 horsepower (depending on the type of engine). Moreover, if the transmission on the machine also works, it is installed on the frame along with the engine.

If you select the most optimal for a homemade tractor, then it is better to make a car with a ud 2 engine. Like the zid power unit, ud 2 was developed by the Ulyanovsk plant specifically for home-made machines for agricultural needs. The power of such an engine is only 4 liters. With. But for processing a small field, it is quite enough. In addition, it is very easy to repair.

If the home craftsman has one, then the task is simplified even more. In this case, not only a power device is installed on a home-made mini tractor, but also a front axle with brakes and clutch, part of the frame and steering.

2.2 What to make the frame of a homemade mini tractor?

Before making a power frame, you need to decide on its type. Many craftsmen make tractors with a breaking frame. This type is an assembly of two halves connected by a movable link. The breakable frame reduces the turning radius, which makes it easier to work on small plots of land and near buildings.

To make such a frame, iron corners or channels marked 8 are needed. In this case, the front half frame should be slightly longer. Recommended dimensions - 900 by 360 mm. The back of the frame is assembled to a size of 680 by 360.

After assembling the frame, two pipes with a square cross section are welded across the front part. This is an engine mount. All other stands and corners are installed based on the intended design. It is desirable to weld the elements. Ordinary bolts may not withstand the load.

Two forks and a hinge will be used as a connection between the half-frames. For the hinge, bearings and a trunnion are taken from a Kamaz car. Such a cardan will allow the rear half to move not only in a horizontal, but also in a vertical position. At the back, a plate is welded to the frame for a hitch.

If it was decided to make a cast frame, two half-frames are welded with additional channels.

2.3 How to make a chassis for a mini tractor with your own hands?

First of all, bridges are being built. For their installation, vertical racks reinforced with corners are welded onto the frame. It is best if the homemade front beam on the minitractor will be of the same type rear. In this case, there will be no need to select a subordinate number, which is almost impossible without proper experience.

If the frame is not breaking, it will be easiest to take the running gear from the Zhiguli. Having slightly corrected it in size, we immediately install it on the frame. In this case, you do not have to separately look for a gearbox for a mini tractor. It is already installed on the rear axle.

If the frame is broken, it is better to use a different scheme. In this case, the front axle on a minitractor is best made from a cast rod, with a diameter of at least 50 mm. In the middle, with the help of a semi-cylindrical lining, a hinge is fixed, which will be responsible for the floating movements of the bridge on bumpy sections. At the edges of such a beam, ears for pivots are installed.

KAMAZ trunnions with axles on the hub are fixed on the ears with the help of pivots. On them .

If you wish, you can make hydraulics on a mini tractor with your own hands and at home. In this case, hydraulic motors are taken from any brand of machine. To install them on the frame, you will need additional pockets on the frame. You can make them with steel corners. The motors are fixed to the frame with strong bolts. Pockets with hydraulic motors are installed near the drive axle. Each motor is designed to turn one of the rear wheels.

To organize the exact direction and speed of rotation over the axis is set. In front, next to the main engine, an oil tank is installed. It must maintain optimal pressure. A special bushing is installed in the middle of the system, which will be responsible for swinging the front axle. To drain the oil, a standard spool is fixed.

Hydraulics will also allow you to work with additional attachments, automating it.

2.4

The hitch is used to connect with additional equipment. In addition, a special power take-off mechanism allows you to automate the operation of such equipment as or.

The most reliable option is a three-point homemade. It consists of a do-it-yourself hitch on a minitractor of two rods that can be taken from any car. The rods are attached to the plate prepared in advance on one side, and to the attachments on the other. The third attachment point will be additional traction and a hydraulic motor drive, which will transmit torque to the working parts of attachments.

In order for everything to move normally, it is better to fix a movable rod with a diameter of 40-50 mm on the plate, and then attach the hinge rods to it.

2.5 How to properly install the brakes and clutch

Brakes are installed on the rear drive wheels. The best option here would be to take the factory version from UAZ. Brake pads are mounted on discs, and control is output to the appropriate pedal inside the cab. If necessary, you can make the brake manual, under the lever.

If you make a clutch, then a standard belt type is suitable for a mini tractor. The easiest option is to take a ready-made mechanism. Suitable clutch with UAZ or Moskvich. With a small engine power, the belt traction of the walk-behind tractor will be enough. The tube that presses on the belt is attached to the frame with a spring that clings to an eyelet welded in the middle. The other end is welded to the pedal by means of a lever.

2.6 Steering column and driver's seat

The steering of a homemade mini tractor is best taken from Moskvich. The only feature of such a mechanism is that in the standard version it turns in the opposite direction. Therefore, instead of the Moskvich rods, the rods from the Zhiguli are installed, and the hubs from the Zaporozhets. A special steel lever, which is installed between the rods and the column, puts the system in the right direction.

As for the driver's seat, it is installed on a pair of vertical corners welded to the frame or on rectangular structures made of square pipes. To reduce vibrations during operation, it is also possible to install the seat on steel shock absorbers with additional fixation with rods.

For convenience, a home-made cabin for a minitractor is easily made from thin sheet steel or tin.
