Do-it-yourself garden mini tractor. How to assemble a homemade tractor with your own hands

All household or small farms have to use a lot of manual labor. It helps to reduce its share assembled mini tractor with your own hands. It can be used for a variety of purposes, including hay harvesting, tillage, crop or fertilizer transportation. Performing such operations without mechanization at home is problematic.

Large agricultural companies solve the issue of buying foreign or domestic agricultural machinery. It is not always possible for small farms to allocate the required amount for a minitractor, so they have to come up with and implement home-made developments. For household with their own hands, the entire assembly is carried out from improvised materials. If necessary, certain power units are made more powerful, and the product is also thought to be as maintainable as possible with a universal set of spare parts and consumables.

Pros and cons of a homemade mini tractor

The wide popularity of this type of technology is provided by the advantages:

Comfortable operation in limited space conditions. For a homemade mini tractor, fields of less than 2-3 hectares are optimal. Larger areas are processed with larger and more powerful equipment.
Not all areas are effective manual digging. This refers to rocky or hard ground texture. At the same time, manual labor will be much harder. It is more appropriate to use in such circumstances a mini tractor for the household, which in a matter of minutes, with the appropriate attachments, will complete the task.
Making a mini tractor with your own hands will often be cheaper, especially when available. power point from other technology. You can make the rest of the nodes with your own hands, the drawings in this case will be unique.
Ample opportunities for reconstruction, restructuring, refinement and repair. Since you yourself will have to make a mini tractor from improvised means, you can lay the prospect of re-equipment in the schemes in advance.
Homemade will have a small weight, which will not create an excessive load on the soil. This makes it safe to use even when caring for crops during cultivation, hilling or harvesting.

With all the positive factors, those who decide to make a mini tractor with their own hands need to be aware of the future disadvantages. Most spare parts will be unique, so sometimes it can be difficult to find analogues. This practice should be taken care of in advance.

Also, the owners of this equipment will be prohibited from driving on public roads. To fix this, you will have to go through a long journey of registering your vehicle. Otherwise, it will have to be transported to the arable land or to the garden not on its own, but on a trailer. You can get a fine for driving a homemade car on a regular highway.

In order to correctly implement the design plan, it is necessary to have real drawings and dimensions of future elements and assemblies.

Unit drawing with dimensions

It is important to prepare the following main modules:

power plant of optimal power;
transmission for transmitting power from the engine to the wheels;
base in the form frame structure;
steering;
place for the driver.

If not the entire set is available, then it is worth looking for the missing parts at car showdowns or at vehicle recycling points. Also, something is easy to pick up at the service station.

We assemble the frame ourselves

The base is often welded from a channel or an I-beam. They are selected from the interval from No. 5 to No. 9. The system will be very solid. Most often, two semi-frames are used for a breaking frame, which are interconnected by movable hinged joints in the form of parts cardan shafts from the truck.

Frame for a future fracture from a channel

Also, the frame can be one-piece, assembled from two spars and crossbars. The crossbar is made of channel No. 10. When using the labor of assistants, it is preferable to have a drawing available in order to obtain the desired result.

Engine preparation

Before you assemble a mini tractor with your own hands, you should take care of the motor. An engine with a power of about 40 hp is considered sufficient. Power plants UD-2, M-67, UD-4, MT-9 fall under this criterion. Also, assemblies based on cylinder blocks from an old VAZ or AZLK are not uncommon.

Masters for housekeeping strive to create all-wheel drive models. We recommend assembling such machines with a 4x4 wheel arrangement based on the M67 engine. In this case, it is necessary to ensure an increase in the gear ratio in the transmission. If this is not done, then the motor will lack torque. It is important in this situation to form an additional cooling system.

It is very convenient to make a tractor from a walk-behind tractor. In this case, ready power unit, front axle, brakes, gearbox, frame and steering system.

In the traditional layout, the motor is located in front, directly above the front axle longitudinally. Through the clutch, a gearbox is mounted to it. Further, according to the scheme, there is a razdatka and a drive axle. The connection of elements in such a scheme is carried out by means of couplings or several cardans.

Sometimes it is more convenient to place the motor on the frame, placing wooden boards under it. In this way, it will be possible to find the optimal position for him. If necessary, brackets are made for convenient fixation of the cylinder block.

It is important to observe the weight distribution in order not to get a quick tipping system. Experienced experts recommend spreading the mass along the axes in a ratio of 60% to the drive axle and 40% to the driven (steered) wheels.

Transmission and rear axle

The most durable and inexpensive gearbox is a box from Soviet GAZ-53 trucks. From them or from the GAZ-52, a clutch system is used. When mounting on a frame, it is worth taking care of additional adjustment of the nodes to each other. There are home models with components from UAZ. Their power parameters maintain a high level of reliability.

It will be possible to synchronize the clutch and the motor through the assembled new housing (basket). You will need to cut the rear plane at the flywheel of the power plant. You will also need to drill an additional center hole.

As rear axle mini tractor, a ready-made assembly is taken from a passenger car or truck. It is important to adjust the dimensions of the axle shaft in such a situation. For a 4x2 wheel scheme, where one of the axles is not leading, it will be easier to select the front axle shafts.

Steering wheel and wheels

So how to do homemade mini tractor is assumed for power loads, it is important to choose a steering with a hydraulic cylinder in the scheme. At home, it will not be possible to make such a hydraulic device, so it can be picked up at a dismantling of cars or agricultural machinery. We will also borrow the steering trapezoid.

As a seat, you can use any suitable object - a seat from a car, an armchair, even a stool will come in handy if it is properly fixed

Wheels for homemade need to choose a radius of more than 13 inches. They are suitable for equipment designed for the transport of goods. If agricultural work is expected, then a radius of 18-24 inches should be preferred.

The support pins are forks from Soviet cargo universal joints. We cook a couple of forks to the beam or directly to the frame, while maintaining alignment. The rest are welded to knuckles.

The use of mini tractors in agriculture has become more and more justified in recent years. Relatively small dimensions, coupled with good performance and maneuverability, make it possible to cultivate land for further use. However, not everyone has the opportunity to purchase a finished unit sold in specialized store, because its cost can reach up to 100 thousand rubles. It was then that many people have a question - how to assemble a mini tractor at home with your own hands?

The solution is not as simple as it might seem at first glance, because the assembly may require a lot of related material, as well as the necessary technical knowledge and the ability to work with tools.

Areas of application of a homemade mini tractor in the household

And in general, you can use the Internet by typing in the address bar the query “do-it-yourself mini tractor drawings dimensions”, and you will immediately see more than one detailed diagram assemblies.

The frame is the supporting structure. Everything is attached to it attachments.

This step is very important because independent production any unit involves a certain refinement and adjustment to the desired parameters. Obviously, it is easiest to do this according to the drawing than to navigate approximately.

Appropriate agricultural machinery is essential for a successful and productive household. By clicking on, learn how to make a cultivator yourself.

Plows have improved characteristics, which allows you to easily cope with plowing any land as quickly and efficiently as possible. everything about various types and characteristics of the PSK plow.

At present, technological progress is helping to replace long human labor with much faster machines. Combine harvester Polissya is your indispensable assistant with excellent quality for decades.

In addition, the same turner will understand what is required of him by looking at a detailed drawing than a formal explanation in words.

At the planning stage of the project, it turns out which unit will be in the end. For many, a do-it-yourself fracture mini-tractor at home, located on an articulated frame, enjoys a certain popularity.

However, this is far from the only assembly method, so the choice lies solely with the person who will carry out the manufacture.

Having decided on the type of mini tractor, the question arises of finding necessary spare parts and accessories. We are talking about the frame structure, engine, transmission, controls and wheelbase. Most of this can be found on the Internet by visiting sites that specialize in the sale of various spare parts.

The assembly process itself will include several stages:

Frame manufacturing. The fracture is carried out mainly from channel number 5 and channel number 9. Two half-frames must be welded from these components, and they will be connected to each other using a hinge. As such, you can use cardan shafts from heavy vehicles.

There is another way to design a frame. It consists in the manufacture of a one-piece structure, consisting of two traverses and two spars. Traverses are made of channels number 16 (for the back) and number 12 (for the front).
The spars will be made of channel number 10. A metal bar is used as a cross member.
As an engine, you can use the models MT-9, UD-2, UD-4, etc. Their power will be quite enough for a home-made version. In principle, any engine with a relatively high power - about 40 hp will do.
The PTO and gearbox can be removed from the GAZ-53, and the clutch can be taken from the GAZ-52. Remember that these details will have to be adjusted to the design parameters. At the flywheel of the motor, you need to cut off the back a little, and also drill a hole in the center.
The steering wheel can be provided with a hydraulic system, which must be taken from old agricultural equipment.
The design of the rear axle can be borrowed from the old cars, but it will have to be slightly adjusted to lathe.
As wheels, you can use any suitable, but that their diameter is about 18 inches - this is an acceptable minimum for agricultural work.
In this sequence, in principle, lies the answer to the question - how to make a mini tractor at home? Most of the necessary components can be obtained from old equipment, which greatly simplifies the issue of finding the right part.

In addition, the costs are minimal, because even the purchased parts will cost much less than the finished mini tractor.

Advantages and disadvantages of manual assembly

Perhaps the main advantage of a homemade mini tractor is the unconditional saving of money, compared with the purchase of full-fledged units in a store, such as,.

At the same time, its performance will not differ much from the factory options, because the design uses a fairly powerful motor, which is enough to process land holdings up to ten hectares.

The cost of manufacturing a minitractor pays off in almost one calendar year, because most of the components are taken from old equipment, or the cost of purchasing them is minimal. Many adapt other equipment, such as a walk-behind tractor, for a minitractor, which further simplifies the assembly process.

In addition, homemade units have other advantages:

Relatively large degree of immersion in the soil. If everything is correctly foreseen, the digging depth will be identical to that shown by purchased analogues. Be that as it may, it is still better than digging the garden by hand.
Sufficiently high mobility, as a result of rather modest dimensions. The use of such units is advisable precisely in small gardens and summer cottages, where large-sized tractors cannot turn around.
Due to the fact that you make a mini tractor yourself, there is the possibility of additional modernization of the unit. You can remove components, changing them to other, more powerful ones, or adding new devices.
There is no such possibility in the minitractors sold, moreover, the operating instructions expressly state that making 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 be adjusted on a lathe, which in itself presents additional complexity.
The likelihood of breakage homemade version It is made mainly from old parts and spare parts.

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

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

Additional Tips and Warnings for DIY Tractor Making

Before you start full-fledged operation of a home-made mini tractor, you need to register it with the traffic police.

This is not a simple formality, but an understandable necessity, because when driving on public roads, penalties may be imposed on you, and the unit itself can be transported to a penalty parking lot.

As for the technical aspects, then there are some specifics. In order for the engine of a home-made unit to give the necessary parameters, i.e. about 2 thousand revolutions at 3 km / h, you need to slightly adjust the transmission scheme. In general, ideally, each wheel of the rear axle should be equipped with a gearbox.

If the basis for a mini tractor is a walk-behind tractor, for example, or some other, then it is better that it has a special hitch that allows you to attach to it optional equipment. In general, you should carefully choose the model of the walk-behind tractor that you want to convert to a mini tractor.

For these purposes, the Centaur walk-behind tractor, which has a power of 9 hp, and also has the necessary technical data necessary for rework, can be perfect.

Conclusion

Making a homemade mini tractor is becoming more and more relevant, especially for owners of small plots of land. The fact is that the use of large-sized tractors may not be practical, because they will not be able to show all their performance on such a small plot of land.

In addition, fuel costs can become a truly unbearable burden for private farmers.

Savings also explain the refusal to purchase a mini tractor in a special store, because agriculture is far from the most profitable type of business in our country. Therefore, for an ordinary summer resident the best option it will be the manufacture of the unit on its own.

At the same time, the costs are penny, and the performance of a finished home-made mini tractor may pleasantly surprise you. Naturally, if used relatively powerful engine and not very old parts.

Do not forget that this method may not be suitable for some people who do not have the proper skills in handling a welding machine or a lathe, for example. In this case, you can simply order the necessary parts from the craftsmen who will make them.

Of course, you will have to pay, but not more than the amount that you need to pay for a finished mini tractor.

As an alternative to the factory tractor for small farms, you can use "folk" designs.

The home-made mini-tractor from a walk-behind tractor described below was created from the parts of the Ant cargo scooter - it has proven itself well when working in small-sized rural areas. You can create such a mini-tractor with your own hands if you have a small workshop and a sufficient share of skill.

The design of a homemade mini-tractor

This design was developed and tested in practice by students of the Kharkov Institute of Mechanization and Electrification of Agriculture.

You can make such a mini-tractor yourself from scrap: various components and parts from old serial machines produced by the domestic industry.

The unit can be equipped with a wide range of interchangeable trailed and mounted implements. Thanks to this, the walk-behind tractor can be considered a universal assistant in home gardening. It can be used for plowing and harrowing, cultivating and hilling, as well as for other operations related to tillage and plant care.

This tractor can also be used in conjunction with a single-axle trolley to transport various household goods, garbage from the site, soil, sand. To do this, a slight modification of the tractor is made, and the driver is placed on a sprung seat in front of the bogie.

The main parts of a homemade mini-tractor are the VP-150M engine, transmission, power take-off system, chassis, control system and hitch. All of them are arranged on a rectangular frame from a channel. The VP-150M engine from the Electron scooter or its equivalent, which has a power of 7.5 liters, can be considered the most suitable for the walk-behind tractor of this device. With. (5.5 kW), single-cylinder, two-stroke and carburetor. It has a compact integrated gearbox and clutch, and is equipped with electronic ignition. It is also valuable that this motor is equipped with a centrifugal fan, because other engines have to be cooled in various "handicraft" forced methods.

You can, of course, use other engines. But for comparison, it is enough to give the basic data on the VP-150M engine. Here, the transmission of torque to the gearbox is carried out by a helical pair of gears with a gear ratio of 3.045.

Gearbox - three-speed - with gears of constant meshing. gear ratios the steps are as follows: for the first gear - 4.883, for the second - 2.888, for the third - 1.800. The engine and gearbox are made in one monoblock. Special requirements for operation and maintenance there is no engine complete with clutch and gearbox, in this case they are regulated only by the manufacturer's recommendations.

The transmission of the walk-behind tractor is mechanical, gear-chain, consisting of a serial differential with reverse (from the Ant cargo scooter), an intermediate shaft, two final drives and a wheel locking mechanism. The intermediate shaft in this mechanism simultaneously serves for power take-off and for mounted implements. Therefore, the torque is transmitted from the engine to the intermediate shaft using a chain with a pitch of 12.75, and then further to the differential using a chain with a pitch of 15.875 mm. And then, again along the final drive chains with a pitch of 15.875 mm, to the drive wheels. The sprocket Z1 refers to the engine, Z4 is a kit along with the differential, and Z2 and Z3 are from the Voskhod motorcycle.

The intermediate shaft is made of steel 40, it is mounted in two ball bearings No. 180205. Standard flanged housings can be used for them (for example, from decommissioned agricultural machines); fastening to the side cheeks of the transmission casing.

The diameters of the shaft seats should be selected according to the dimensions of the sprocket hubs. The length depends on the width of the transmission housing plus a small margin (for installation with right side two-stream drive pulley diameter 100-120 mm).

As you can see in the photo, this homemade mini-tractor is a two-wheeled vehicle driven by a person walking behind it.

How to make a mini tractor for the household

The frame of the walk-behind tractor can be welded from suitable profiles at hand. For the longitudinal side members of the frame, you can use channel No. 6, and for the transverse side members - No. 8. From below, to the horizontal side members of the frame and to the brackets, it is necessary to attach the bearing housings of the axle shafts with bolts. Here it is required to put bearings No. 180207 (two for each axle shaft). Cases for them should be selected standard (preferably from decommissioned agricultural machines).

The installation of these elements on the brackets must be carried out with particular care: it is necessary to observe the alignment of the wheels and the perpendicularity of the semi-axes relative to the longitudinal axis of the frame. This is important for the subsequent marking of the holes for fastening the housings with bearings and their further mounting on a one-piece mandrel axle, which subsequently must be sawn into two axle shafts.

With the correct installation of the housings, the mandrel in the bearings of the axle shafts will rotate freely.

After that, corners 25 x 25 mm should be welded to the frame in its rear part. Next, a transmission casing made of steel sheet 5-6 mm thick is screwed to them. This element is necessary as a basis for installing the intermediate shaft, differential and control mechanism. The rear side of the casing should have a removable cover, and the front side should have a bracket for attaching the fuel tank.

The front part of the frame is equipped with welded corners from the inside, which will serve as a bracket for the engine with a forced cooling fan.

The axis (or half shafts) must be made of high-quality steel. The dimensions of this element can be adjusted depending on the available bearings and the dimensions of the wheel hubs. Further on the semiaxis with inside you need to plant two half-couplings.

The right clutch half must move freely on the square, and with the help of a lever mounted on the control rod, it must be engaged with the left clutch half. Thus, a rigid connection of the axle shafts is provided, i.e., the wheels are blocked.

The traverse must be rotated by 180 ° or by the required intermediate angle so that additional convenience is possible when controlling the walk-behind tractor during operation.

Watch the video "Homemade mini-tractor" to clearly see how this agricultural machine is designed:

Adaptation to a mini-tractor for quick watering

For quick irrigation of a large land plot, craftsmen offer another kind of homemade tractor. Rather, it is a device that attaches to a mini-tractor. In this case, a four-wheel version of a mini-tractor is used.

In addition to watering, the mini tractor for households can be used for various tillage jobs with this attachment and with the help of various trailers and attachments.

This design was developed on the basis of the UD-2 engine with a power of 8 liters. With. The tractor frame is recommended to be welded from pipes with a diameter of 40 mm. For its rigidity, it is necessary to weld squares measuring 35 x 35 on the sides. The rear axle and driveline can be taken from a Skoda car. These parts need to be cut a little and fit according to the drawing. The gearbox can also be taken from this car (it has three speeds for forward and one for reverse). Front axle it is quite possible to calculate and make it yourself from a 40 mm pipe in the form of a rocker arm. Traction is taken from a motorized carriage, and steering column- from the car "Volga". Brake system must be hydraulic, the brake cylinder - from the GAZ-51 car, the gas tank - from the grain loader. And the tractor seat can be taken from a beet harvester and redone a bit. The wheels for this tractor, front and rear, were taken from a tractor rake.

The result is a complete machine. On the front of the frame assembled tractor it is required to place only the irrigation unit. It should consist of a gear pump taken from the hydraulic system of the MTZ-5 tractor, which will operate from the drive of the tractor engine.

At the end of the assembly, a water tank with a capacity of at least 200 liters must be installed on the tractor frame. During operation, the pump will pump water and deliver it through a hose, thus watering the ground within a radius of up to 10 m.

A mini tractor is exactly the same agricultural equipment as a tractor, but with a slightly lower performance, which is sacrificed for the sake of maneuverability and economy. In addition, some specimens are so light that they are transported in a trailer. Small tractors perform all the same tasks as higher class counterparts. You can also attach attachments to them for tilling and fertilizing the soil, cleaning the territory and transporting various goods. In addition, in many tractors, even those made independently, there is a rotation drive auxiliary units and hydraulics.

It differs from a walk-behind tractor, first of all, in that it is a full-fledged agricultural machinery. Of course, a powerful walk-behind tractor also has considerable functionality, but when managing it, you have to walk all the time. This is very tiring, especially when processing a large area of arable land. And by making it a self-propelled machine, even the smallest, the operator gets tired much less.
Understanding all the advantages of minitractors, domestic inventors create with their skillful hands, sometimes first-class specimens, and on the Internet you can now find many descriptions, diagrams and even ready-made drawings of such homemade products.

Designs of mini tractors

For the most part, amateur designers in the manufacture of a tractor simply remake some serial product, adding some components and eliminating others. This is an easy way, but it is not always feasible, because. a complete machine must be available.
And the design of homemade tractors created from scratch is individual in each case, so today the variety of solutions just rolls over.
For example, the frame for a minitractor is made integral and breaking (called a “break”), the turn is made with steerable wheels and onboard, the layout is classic or in the form of separate modules that allow you to change the purpose of the device. Install hydraulic system and power take-off shaft.

Tractor from the manufacturer at the price of a homemade product - the whole the lineup. We buy good attachments for a home-made agricultural machine at the link. We read in this article - the easiest way to assemble a mini tractor from a walk-behind tractor.

The homemade mini tractor offered below is one of the easiest to manufacture and allows you to get by with the available materials and parts.

But, of course, for those who are going to do something themselves, with their own hands, it is recommended to have technical skills, the ability to work with a tool and read drawings. And, most importantly, to have a lot of time and a great desire to do it.

Frame

It is made from rolled metal. Calculations for strength are a thankless task (and in this case, not necessary), so you just need to lay in advance a multiple stock. Based on this, apply a channel from No. 6 to 12 - best solution for a homemade mini tractor. It is not worth doing any “recesses” and “roundings” of the units, because. this will greatly complicate and increase the cost of the project. The usual flat "ladder" is simple and accessible to many.

As practice shows for a homemade tractor, it is more useful to use a larger rolled channel (up to 20) as the front and rear traverses (crossbars), because. subsequently, it is to these traverses that various working bodies and auxiliary equipment are attached. And it is better to have it shelves inside. Channel spars (longitudinal beams) can be positioned both inside and outside. Fuel lines and lines are laid inside the spars, which are naturally protected.

In shape, the simplest frame design for homemade is a rectangle with two or more traverses, but a frame in the form of a trapezoid will have much greater rigidity. The width in the front part should be smaller to accommodate the minimum dimensions of the steered wheels, as well as to be able to observe the movement strictly along the arable row. The joints of the spars and traverses must be strengthened by welding scarves.

Layout

The relative arrangement of the units of any tractor has historically developed a long time ago.
Classic layout self-propelled machine next: the engine is located in front, longitudinally, above the front axle. A gearbox is connected to it through a clutch, followed by a transfer case and a drive axle behind it. Between themselves, the shafts of the units are connected using cardans and (or) couplings.

Compliance with this scheme will be the best option when creating a mini tractor, because. allows you to apply existing aggregates without changing them.
According to the experience of many creators of homemade tractors, it is better to assemble the units “in place”, without doing unnecessary drawing and calculations. The best option- on the finished frame, place all the main components and homemade mechanisms by installing them on temporary supports (conveniently - on wooden blocks), and, having found the best mutual position, make mounting brackets. But we must not forget that all the nodes on homemade tractor must be secured through vibration-damping supports (rubber pads). It is best to borrow them from the same equipment from which the unit was taken. Another important factor must be taken into account. This is weight distribution, i.e. distribution full weight minitractor on the front and rear axles. The most acceptable option - 60% of the weight falls on the drive wheels, 40% - on the driven ones.

Homemade engine

From the point of view of thrust-to-weight ratio, weight, accessibility and low cost of repair, it is most logical to use an engine from VAZ cars of classic models - from 2101 to 2107 when manufacturing a tractor in "home" conditions. They can be found in good condition at the price of scrap metal. With luck, one machine can become a donor of most parts for a mini tractor.

The motor with clutch and gearbox is fixed as a single unit, which simplifies the work on a homemade tractor and saves the creator from many difficulties. Be sure to install a fan impeller on the shaft of the water pump ("pump"), even if it was not there. After all, the speeds of agricultural machinery are much lower than those of automobiles, so the operating mode of the minitractor motor is the same as when standing in a traffic jam, which is considered difficult for any engine. Therefore, the radiator of the cooling system of a homemade tractor needs forced airflow.

Transmission

As mentioned above, it is desirable to install the entire power plant on a homemade product. In this case, what will later become a mini tractor will already have at least four gears forward and one reverse. It remains only to agree on the optimal tractor engine speed and the desired speed. For this, a transfer case from any all-wheel drive car will be quite enough. The most suitable option is UAZ. By the way, the previously considered components can also be used from UAZ, but they are heavier, the consumption of the resulting tractor will be higher, and all its power will rarely be used.

A good element for connecting the shafts is an elastic coupling, which is installed on the output shaft of the VAZ gearbox. Having made a flange to transfer box, you can do without an intermediate cardan. But from the "razdatka" to the drive axle, the cardan is required, because. the loads there are significantly higher, and the clutch will not withstand them.
When building a tractor on your own, it is best to use the drive axle also from a UAZ vehicle with final drives. This will increase, firstly, traction, and secondly, ground clearance (which is desirable to bring up to 450 mm). The required track size of a home-made mini tractor is obtained by cutting the stockings of the bridge (narrowing it) or by making spacers for attaching the wheels (expanding it), because. the nominal gauge of the UAZ is 1445mm, which does not coincide with the accepted ranges for agricultural vehicles (1260-1285, 1350-1370, 1490-1515, 1790-1815).

Chassis and propulsion

This system for the considered home-made mini tractor almost completely repeats the similar one for tractors manufactured by the industry and differs from the automobile one in some ways. important points. The main difference is the absence rear suspension, i.e., the drive axle is not attached to the frame on the springs, but is rigidly fixed to it. This must be done if it is planned to make not only the tractor itself, but also all the agricultural implements for it with which it is supposed to be used. Since attachments such as plows, harrows, mowers and others, attached to the back of a homemade mini tractor, are very heavily loaded rear axle and, if present on the last rear suspension, will quickly render it unusable. The front axle on a homemade tractor can also be installed without suspension, comfort will not decrease significantly. It is convenient to use forks as pivot pins cardan joints trucks (ZIL, KAMAZ, KrAZ), spare parts for which can be found in car fleets and metal receiving stations. Two forks are welded to the beam, or directly to the frame, observing alignment, and two reciprocal forks are welded to the steering knuckles of the donor car. The steering trapezoid, together with the steering mechanism, is also entirely borrowed.

The braking system in her automotive form"It makes no sense to use it on a tractor made by oneself, because not those speeds. Just the parking brake is enough. However, the mechanism is driven not from a lever, but from a pedal with a fixed pressed position. Then the homemade product can be slowed down in motion, and fixed in the parking lot. Wheels are best used from agricultural machines, because. they have the desired tread, but it is quite possible to adapt tires from SUVs or light trucks by cutting the desired tread pattern onto them (preferably a herringbone, for self-cleaning). Tire pressures are selected empirically to find the optimal combination of comfort and performance.

Electrician on a homemade tractor

You can use any parts from anything, the main thing is that the voltage of the generator and consumers match. We must not forget that accumulator battery- this is a container with acid, so it must be very firmly fixed. The recommended solution is to place it under the seat of the minitractor in a special box, or simply in a fence.

Headlights and marker lights, as well as brake lights are desirable elements, but not mandatory, because. You can only exploit the result of your labors away from other transport.

Road traffic

Not all homemade mini tractor designers go to public roads. And rightly so, because in our country, a number of stringent requirements are listed that must be met by vehicles moving along them. Even if everything turned out well, and the product meets all the requirements, certification will be necessary to confirm this, which is very expensive.

Therefore, it is forbidden to drive on the roads on a homemade tractor. If you have to deliver it to the place of work, then it is better to do it on a trailer. This is one of the reasons why they are trying to make homemade products easier.

In the modern world, many people have country houses where a lot of manual labor is used. In order to make their lives easier, many decide to buy a mini-tractor. However, such a purchase can hit the budget hard.

In order to avoid this, many decide to make homemade mini-tractors. This will help to significantly reduce labor costs for working in the garden and save money.

Advantages and disadvantages

What are the pros and cons of this product? Firstly, you can operate a mini-tractor even in a very limited space - it will fit perfectly into a small garage on backyard. However, despite the fact that the size of a homemade tractor is relatively small, this will not affect the functionality and amount of work performed.
