It all started with the fact that I bought LuAZ (Volynyanka in the people), they wanted to hand it over for scrap. The engine was killed (the engine on this car was from a Cossack), the body was rotten, but everything else was almost in good condition. He took the gearbox, steering gear, axles and wheel gears, electronics, and cut everything else and handed it over for scrap. There, he got back some of the money he spent.

Homemade mini tractor with a diesel engine from the Sadko DE-300 walk-behind tractor and 4 wheels 6x12.

I welded the frame for the mini tractor from a 40x40 profile, but later I strengthened it (I welded 2 40x80 profiles).

Over time, the "skeleton" began to grow and already became a bit like a mini tractor.

The engine is combined with a gearbox with a belt drive. I used 2 belts profile B, I reduced the speed with pulleys by 3.5 times.

Now I'll tell you about hydraulics for a mini tractor. I installed an NSh-10 pump, a P80 distributor, and a 75x110 hydraulic cylinder. The pump does not work all the time, I can turn it off if I wish. To do this, I made a switchable drive from the gearbox parts of a Ural motorcycle. He removed the shift fork, shaft, two gears and splined clutch. The shaft had to be cut off, and then increased by 5 cm so that an asterisk could be put on. The drive housing was welded from a 40x40 corner, the sprocket and chain were used from the IZH Planet motorcycle. Oil was poured into the drive, so the housing was made airtight and an oil seal was placed on the shaft.

The pump works at 1000-1100 rpm, turning its shaft coming from the clutch flywheel.

And a video of the hydraulics. The central section of the distributor is for hitching, and for the other two I brought the couplings to the front and rear. I attach a mower hydraulic cylinder to the rear coupling, and in the future there will be a dump truck trailer and possibly a wood splitter. And I attach a rotary blade to the front clutch.

Here is such a homemade mini tractor with various useful devices and canopies made by the craftsman Vyacheslav Nevolya

All household or small farms have to use a lot of manual labor. Do-it-yourself assembled mini-tractor helps to reduce its share. 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 a do-it-yourself household, 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 turn out to be cheaper, especially when a power plant from other equipment is available. 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 of a 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 articulated joints in the form of parts of cardan shafts from a 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.

Household masters 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, the power unit, front axle, brakes, gearbox, frame and steering system are already ready.

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 the rear axle of a 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

Since it is supposed to make a home-made mini tractor for power loads, it is important to choose 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 the steering knuckles.

VIDEO: Interesting ideas for assembling a homemade tractor and attachments

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.

2.7 A detailed review of a homemade mini tractor (video)

The presence of your own mini-tractor in the household greatly simplifies the implementation of a large amount of household tasks. One of its main advantages is economy and mobility in management in limited areas. It is enough to equip your homemade tractor with all the additional devices, and it will be an indispensable assistant when processing not very large land areas.

In the conditions of running your own business, associated with the production of agricultural goods on personal plots, the tractor is an effective technique. Since not everyone can afford to purchase new special equipment at the initial stage of business development, but building your own home-made mini-tractor and everything for it from improvised parts is absolutely within the power of those who have basic knowledge of plumbing art.

With the help of your homemade 4x2 mini-tractor, you can to implement the whole list of specific works:

• snow removal;
• transportation of not very large cargoes;
• cleaning household garbage, as well as various vegetation;
• hay making;
• planting and digging vegetables, etc.

There are quite a few options for the production of homemade mini tractors. Some homemade things are designed on the basis of engines from old domestic or foreign cars and motorcycles. Others are selected from existing equipment such as a minitractor.

Creating a homemade mini-tractor

A do-it-yourself tractor includes a complex set of structures and elements that are directly interdependent. Before you start work, you should decide on the design of the homemade product, which you can read about on the forum. Therefore, the presence of drawing materials at hand will greatly facilitate its production.

In order to carry out production at the proper level, the craftsman will need:

• study of basic knowledge of adaptation;
• the presence of a single series of nodes (box, power unit) and mechanisms.

In addition, the presence of a layout and drawings will serve as a guide in the direction of the formation of a home-made device.

The design of the mini tractor

The described design was invented and tested in practice, which can be read on the forum. Make such a mini tractor with your own hands allowed from scrap: different components and elements from the previous production cars produced by the domestic industry.

The unit can be equipped with a huge set of plug-in trailed and outboard implements. Thanks to this, the mini-tractor can be considered a multi-purpose assistant in home gardening. It is allowed to be used for the purpose of plowing and harrowing, cultivation and hilling, and, in addition, for the purpose of other actions related to cultivating the land and caring for plants.

This tractor is also allowed use in conjunction with a single-axle cart to transport various household goods, garbage from the site, soil, sand. To do this, a slight modification of the tractor is performed, and the driver is seated in front of the cart.

What will the mini tractor be made of?

The first thing to do before assembling the equipment is to find out what nodes it consists of, which you can read about on the forum.

The simplest adaptation of a compact tractor includes the following elements:

• hydraulic motor (a walk-behind tractor or a motorcycle can act as a motor);
• a power frame in which all other installations are fixed;
• brake system;
• assembly with brake discs;
• chassis, including wheel axles and wheels;
• hanging equipment attachment system;
• steering column;
• comfortable seat for the operator;
• rear and front lights.

Each of the mentioned parts must be bought, found and assembled starting from a clear general drawing, in order not to violate the proportions of the unit.

How to make a homemade mini tractor?

In order to design such a technique, many methods are used, however, as a rule, the algorithm is the following:

Drawings for a mini-tractor can be found on the Internet, choosing the right type or developed personally, if you have knowledge of a mechanic.

Types of hanging equipment

To increase the interval of perspectives, this device can be additionally equipped with hanging equipment, which can be done using existing improvised means.

So, You can make the following types of hanging equipment yourself:

• variety of seeders;
• hillers and rippers of the earth;
• plows one-, two-body, simple and rotary;
• collapsible mowers for fodder harvesting and more.

Over time, this kind of tractor can be upgraded by defining auxiliary devices that will increase the comfort and safety of control. In addition, such a unit, according to its own personal useful and multifunctional distinctive features, will in many ways overtake most industrial modifications.

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 a 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 assembly diagram.

The frame is the supporting structure. All attachments are attached to it.

This step is very important, because the independent production of any unit involves some 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. all about the different types and characteristics of the PSK plow.

At present, technological progress is helping to replace long human labor with much faster machines. Combine harvester Polesie 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 minitractor, the question arises of finding the necessary spare parts and components. 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. In this capacity, cardan shafts from heavy vehicles can be used.

• 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 old cars, but it will have to be slightly adjusted on a 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 breakdowns, because the home-made version 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 additional equipment to it. 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 would be to manufacture 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 you use a relatively powerful engine and not very old spare 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.
