If the theater begins, as they say, with hangers, then the creation homemade tractor - That's certain! - With acquisition power aggregate and main nodes of transmission. I am pretty lucky in this regard. It was possible to get a well-preserved engine from MP-800B motor-pump; clutch borrowed from the car ZAZ-966; The gearbox from the type of GAZ-52 and the rear axle from the dispersed electric car EP-103K. They were based on the basis of a mini-tractor (MT), who received, according to the unanimous opinion of fellow villagers, a good-quality, irreplaceable mechanical assistant.
Such everything is under the power: and plow the land, and any agricultural culture to plant-tremble, and the crop to collect-bring, and drink wood, and pump water - please! For this purpose, the possibility of power take-off, the use of mounted and trailed agricultural circulation, hydraulics, finally.
Engine internal combustion
(DVS), however, I had to modify somewhat. Moreover, the improvement is not other than the water cooling system with forced circulation Coolant. To enter the latter to each of the two cylinders available separately, and the circulation has improved. To do this, I recommend to do the following.
First of all - to remove the regular aluminum nozzle connecting the head cooling shirts cylinders in DVS. Then, turn out from the holes of the heel heads - those by which the fastener of the dismantled pipe on the engine was carried out. After that, in the holes (on each head), cut into the m22 by the thread - under the pre-prepared new fittings (see Fig.). Complete work on cylinder heads by the fact that the new fittings installed into their places are combined with duret hoses with a radiator nozzle. Now turn over the silencer. In order not to interfere, it is simply removed. After that, retreating from the lower connector of 45 mm, in the shirt of each cylinder the hole is drilled 0 15 mm. Do not forget about the holes for the heels of the water pipe. Cutting the MB by the MB threads, fix these studs in them. And making the pipe with the flanges from the CDZ, set the latter on the prepared places using sealing rubber pads And nuts M8. These inlet nozzles are connected to the injection (water pump), which is used again in dural hoses.
Click-increasing
To improve the circulation of the hole in the gaskets of the cylinder heads, increase the diameter of 10 mm. The coolant circulation itself provides water pump (from car UAZ-452). Strictly speaking, the exact place of its installation is not of the principle value. But it is most convenient, apparently to mount the water pump on the side of the head of the second cylinder instead of the removed vacuum apparatus of the motor-pump. The pump is driven by the clinorem transmission from the driven DVS gearbox.
And another number of features. In order to maximize layout seals, the simplification of the entire design itself is placed ... Ahead of the radiator, at the entrance of which a tee is installed. And the latter is screwed into the latter. The coolant temperature pointer sensor. On the frame of the engine is installed on two crosscrumbs. And the launch is carried out manually, with the right (in the course of the movement) of the tractor side, for which the vertical handle contains here is a sharp turn on itself and down. Moreover, the starting sector and the ratchet washer are factory, and the lever is made of a segment of the half the tube.
Engine reducer - The most, perhaps the complex force of the power transmission from those that will have to be made. Single, single-stage, with a gear ratio I 1.0. The need to enter it into MT kinematics (see Fig.) Is caused by a number of reasons. And above all, the fact that our mini tractor is a double main gear. So, you need to change the direction of rotation of the shaft. There is no doubt that the absence of a gearbox in this kinematics (the connection "directly") would extremely difficult to take power. In addition, it would be possible to start the integration of the DVS manually using the factory start-up mechanism. The connection option "directly" requires the installation of the magneto inverse rotation. And most importantly, the engine shaft will additionally be loaded: from axial effort.
arising when the clutch coupling is turned on.
Case reducer Welded. Made of 4-mm steel sheet (sz) with two welded tight bearings. He has a screw-screwing sapun, and below the drain plug. It is closed with a lid with a welded Bearing support N2208. The gears located inside the two pisceliness are taken ready (from the gearbox of the P-350 launcher or from SMD-62). But the hubs are homemade, made of steel 45.
Flywheel and clutch - From the car ZAZ-966. Successfully fit successfully, fit into the MT design. True, the fifth released Bearing It was necessary to crush up to a diameter of 35 mm - for the free passage of the primary shaft of the gearbox. And for fastening the flywheel to the flange of the slave shaft of the gearbox, the engine is to use three ML 4 bolts (see Fig.).
Transmission Take from the car GAZ-52, followed by refinement. And the essence of the latter is that the glass of the zero ^. Then the bearing by 20 mm is shortened. Performing this operation for creators homemade technology - Not news. As, however, the cutting of the ologonic thread of the opposite rotation, which will need to be fulfilled with all accuracy.
Well, with the main transmission, the modified KP connects cardanian hinge. And it consists of two floals ± g Tsev cardanian Valataken from the same GAZ-52, interconnected crosslinked.
Rear axle (it is also a presenter) - from the electric car (electric loader)
EP-103K. Such a technical solution allows us to achieve not only enough tricks road Suit At MT, but also significantly simplifies the kinematics of the entire car, at all without reducing its operational qualities.
The whole thing here is in the design features of the node used. Indeed, in a single block with the leading bridge, EP-103K contains a traction electric motor, on the rotor shaft of which the gear of the first stage of the main transmission (double) is installed. It means that it is enough to perform a small refinement, and you can safely embed this bridge to our mini tractor!

As for the specific operations on the alteration, so important for the reliable operation of the node transmission, then the essence of them are in shortening on the electric motor housing, pre-removed from the drive axle of EP-103K, up to 70 mm and installation (rotor) of a specially made homemade welded design shaft .
The latter and will not be different as the leading shaft of the cylindrical transmission rear bridge. It consists (see Fig.) Of the two parts: Slotseva (taken from the main transfer of the main transfer of GAZ-52 car; ensures reliability of the fastening of the "cardane transmission" flange) and welded, pre-pulled out of steel 45. After connecting both parts of the welding, the resulting shaft is subjected. heat treatment (hardening and vacation).
In addition to the shortened housing, the Bearing shields (flange-covers) are also used from the former standard electric motor of the EP-103K loader in the design of the MT. Moreover, the rear - after refinement under the bearing support from a screw of the harvester of the header (see Fig.).
The rear axle of the EP-103K loader (the final transmission with the conical gears and differential) is used in the design of the mini-tractor unchanged. In principle, it is possible to do without shortening the body of the boarded electric motor, if there are no hard restrictions on the layout of the tractor, which are mainly associated with an undesirable increase in MT length. It is enough in this case to make the "shaft-shank" for the size of the hull of this "electric motor".
The brake system in the considered. WT - hydraulic, on rear wheels. And some changes in the factory design of the most leading bridge EP-103K for it successful work not required. Especially if the main cylinder is from the GAZ-52 car (0 32 mm).
Considering the high load that a minitractor motor is experiencing, as well as long work At high frequencies, such an aggregate requires a very responsible approach. It turns out that the engine of any tractor as a whole works in high wear mode, as it goes, as they say. To create best conditions For its uninterrupted functioning, it is important to fulfill the following activities:
- Pour exclusively high-quality synthetic or mineral oils (recommended by the manufacturer);
- control the coolant level;
- prevent long-term engine overloads;
- good to warm the motor before work in winter time;
- do not exceed the operational load on the minitractor;
- periodically perform computer diagnostic engine;
- perform repair work Only with knowledge, as well as on specialized maintenance stations.
Good and reliable engine The minitractor, the price of which depends on its model, type, performance and power, usually has a warranty period of operation, which is issued by the manufacturer. Most often, such a period is 12 months during which the company guarantees the smooth operation of agricultural equipment, but this period may be greater. It all depends on the characteristics of the motor, as well as it performance characteristicsso when choosing follows special attention Details from these parameters.
Domestic and foreign engines. What is common and what differences?
Traditionally, our compatriots are more trusted by foreign engines, considering them better and more reliable. With regard to the Japanese and German technology, there are foundations here, since when designing engines, more high-quality steel and brass alloys use, all elements undergo appropriate strength tests, the assembly is controlled at a high level. but ordinary engines For mini tractors, Chinese production is little less inferior in quality by Russian, so our models here successfully compete with overseas. In addition, it is not necessary to forget that domestic engines are designed to take into account extreme winter frosts, and therefore are guaranteed to begin at a minus temperature.
In conclusion…
Summing up the above, it can be said that, from the performance, reliability and power of the engine of a minitractor largely depends on its ability to perform one or another operation. That is why choose the model of such a car is important, taking into account the objectives and tasks that must be performed. The main indicators here is the optimal ratio of power and consumed fuel, since this directly affects the profitability of the technique. Any farmer understands this perfectly, and therefore independently determines the ratio that is suitable for him.
Among the difficulties that wait for the creators of homemade mini-tractors (MT) literally at every step, three, judging by the editorial mail, the most interesting: difficulties with the development of the development of a reliable and fairly strong engine, a compact gearbox and rear axle, whose design determines in many respects Mobility of the car and her appearance, and maximum road clearance ...
Come out of the designed hard position in different ways. Often - adapting to the homemade MT thoroughly moved nodes from the materially chosen technique of factory manufacture. And here from the "Mixture of a Bulldog with a Rhino", sometimes quite successful structures are obtained. As, for example, created by the Penza craft and a long-time admirer "M-K" N. Goncharov, a small-sized tractor-universal.
If the theater begins, as they say, with hangers, the creation of a self-made tractor is certainly! - With the acquisition of the power unit and the main nodes of the transmission. I am pretty lucky in this regard. It was possible to get a well-preserved engine from MP-800B motor-pump; clutch borrowed from the car ZAZ-966; The gearbox from the type of GAZ-52 and the rear axle from the dispersed electric car EP-103K. They were based on the basis of a mini-tractor (MT), who received, according to the unanimous opinion of fellow villagers, a good-quality, irreplaceable mechanical assistant.

For this purpose, the possibility of power take-off, the use of mounted and trailed agricultural circulation, hydraulics, finally.
The internal combustion engine (DVS), however, I had to modify somewhat. Moreover, the refinement is not other than the water cooling system with the coolant coolant circulation. To enter the latter to each of the two cylinders available separately, and the circulation has improved. To do this, I recommend to do the following.
First of all, it is possible to remove the standard aluminum path. Under the pre-prepared new fittings (see Fig.). Complete work on cylinder heads by the fact that the new fittings installed in their places are connected by duret hoses with a radiator nozzle. Now the queue for the silencer. In order not to interfere, it is simply removed. After that, retreating From the lower connector of 45 mm, a hole of 0 15 mm in the shirt is drilled in the shirt. Do not forget about the holes for the studs of the water pipe. Cutting the MV by the threads, fix these studs in them. And making pipes with flanges, install the latter for the prepared places Using sealing rubber gaskets and nuts M8. These inlet nozzles are connected to the injection (water pump ) What is the dublic hoses again apply.

To improve the circulation of the hole in the gaskets of the cylinder heads, increase the diameter of 10 mm. The coolant circulation itself provides a water pump (from the UAZ-452 car). Strictly speaking, the exact place of its installation is not of the principle value. But it is most convenient, apparently to mount the water pump on the side of the head of the second cylinder instead of the removed vacuum apparatus of the motor-pump. If needed spare parts for a motorized selection of models that way. The pump is driven by the clinorem transmission from the driven DVS gearbox.

True, the fifth of the frozen bearing had to squander to a diameter of 35 mm - for the free passage of the primary shaft of the gearbox. And for fastening the flywheel to the flange of the driven shaft of the gearbox, the M14 bolts (see Fig.).
The gearbox is taken from GAZ-52 car, followed by refinement. BUT
the essence of the latter is that a glass of vigorous bearing by 20 mm is shortened. Performing this operation for the creators of self-made equipment is not news. As, however, the cutting of the ologonic thread of the opposite rotation, which will need to be fulfilled with all accuracy.
Well, with the main transmission, the modified KP is connected by a cardan hinge. Moreover, it consists of two FLants of the cardan shaft, taken from the same GAZ-52, interconnected by the cross.
Rear Axle (it is also presenter) - from the electric car (electric loader)
EP-103K. Such a technical solution allows us to achieve not only a fairly large road lumen at MT, but also significantly simplifies the kinematics of the entire car, at all reducing its operational qualities.
The whole thing here is in the design features of the node used. Indeed, in a single block with the leading bridge, the EP-USK contains a traction electric motor, on the rotor shaft of which the gear of the first stage of the main gear (double) is installed.

As for the specific operations on the alteration, so important for the reliable operation of the node transmission, then the essence of them are in shortening on the turning machine of the electric motor housing, pre-removed from the drive axle of EP-10PC, up to 70 mm and installation (rotor) of a specially manufactured home-made welded structure .

Brake system in the considered. MT - hydraulic, on the rear wheels. And no changes in the factory design of the most leading MOST EP-10PC for its successful work is required. Especially if the main cylinder is from the gas-52 car (diameter 32 mm).
Minitractor do it yourself
If you have a house in the village, and even more so you live there all the time, you know what real troubles are at the farm. Without transport when conducting household It's just impossible to do. The best for these purposes is a minitractor, with its help you can ensure the implementation of all needs, from the loosening of the Earth under sowing, before the carriage of large and small cargo. But this technique is far from cheaper, how to be? There is one option - make a minitractor with your own hands. Yes, the task is not easy, but if we handle, save a bunch of funds, and satisfaction from the finished apparatus will come every time you start working with the tractor.
What version of the homemade mini tractor to choose
Camel Mini Tractor for Household with Loars Rama
The best version of the mini tractor homemade is a machine with a broken frame. Such an aggregate consists of 2 parts of the rear and the front, the grip of which is carried out by a special hinge mechanism. In front of all control mechanisms, as well as all chassis. Control is carried out by means of steering wheel and hydraulic cylinders, the entire design bends on the hinge and changes the mutual arrangement of two parts of the tractor. Thus, if you use this design, you can save on some details intended for installation of control mechanisms, which under normal conditions are located in the rear of the machine.
The back of such a minitractor according to the design is much easier than the front. It consists of a rear axle, which is fixed in the lodgers on the spars of the semi-axis, the seat for the driver is installed on this design, and the device for fastening attachments from the tractor Belorus. Differential and semi-axes can be taken from any loader. The suspension on the back can be done, but this is not very advisable, usually depreciation is achieved due to the small pressure in the wheels.
In addition to the simplest design, such a mini tractor has several advantages:
- Large production capacity, this device is able to give the power close to big tractor, especially if you collect the all-wheel drive tractor with a hinge frame;
- The ability to turn around at the minimum area, the radius of the reversal of this device is minimal due to the broken frame design. The tractor can be expanded by 360 degrees in almost one place, this is a particularly useful property when plowing the Earth;
- Small fuel consumption, but this indicator depends on constructive features machines, but most often consumption is minimal;
- Relatively low cost of assembling unit. If you buy such a tractor collected at the factory, then the amount will force their eyes to the forehead. And if you make it yourself, you can get a significant markdown, since the structural elements are used for the assembly, which can be obtained at the lowest prices.
Drawings - the first stage of assembly
Drawing of minitractor
Cinematic diagram of a minitractor
Before you take for the tools, you need to thoroughly ponder the entire design of the tractor itself and the clutch diagram of two parts. The correct drawings are the basis of the foundation. It is best to find reliable drawings from foreign sources, as it is very difficult to foresee all the design features, because the tractor is a very complex complex of interrelated mechanisms. It is necessary to think through the location of all elements of the system so that they can interact efficiently with each other. First of all, the basic tractor nodes and the driver's place are applied to the drawing. If you are not particularly knowledgeable in the issue of drawing up drawings, you can ask for an experienced fit to help you with this problem, and then independently disassemble the plan and make a tractor.
Second stage - reading drawings and assembly of the whole design
When you found the necessary drawings, you can go to find the necessary components and assembling them into a single system.
Remember, when searching for details, pay the most attention to three groups of spare parts: engine, chassis and gearbox - they must be removed from one type of technology, so it will not be necessary to perform their fit to each other.
Selection of engine and transmission
UD-2 engine
In choise suitable engines For a homemade minitractor does not shine a variety, most often have to choose from what is and most suitable. Best in economic and production indicators, for installation on a tractor of such a design, 2 types of engine UD-2 or UD-4 are suitable, but, in general, you can use diesel engines With one or two cylinders. You can, if you manage to find, use M-67, in its characteristics the main is the long service life at minimum maintenance costs.
Before installing, such an engine is necessarily upgraded, a gear ratio increases in it, it is also necessary to come up with a cooling system, since it does not have such. For cooling, you can install a fan that is attached to the crankshaft with the suburban casing to direct the air flow.
Sometimes in quality power plant Use engines from Muscovites or Zhiguli. At the same time, when the engines are extracted from the machines, along with them gets the gearbox with transmission, remember, therefore, you do not need to fit and look for additional details.Wheels are selected based on the purposes for which transport is manufactured. If you plan to use it only for the carriage of goods, dragging them and other such works, you can take discs to 16 inches. If the use of a minitractor for field work is assumed, it is better to take more massive wheels with discs from 18 to 24 inches, in order to improve the quality of the clutch of the wheels with the surface.
Loars Rama
The broken frame consists of two semi-frames, the grip of which is carried out by a hinge compound. To make such a connection, you can use a cardan shaft with a large-sized cargo transport, for example, gas-a. If we talk exactly about cars, it does not matter exactly which model it will be, because cardan Valah Any of them do not have practically no design features. The robe itself is best done from the 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 performed from the profile of any characteristics. Since the strength, for example, for wings is not the most important indicator.
Some features of mounting
The control system in the tractors of this type must be necessarily equipped with hydraulic cylinders, it will significantly improve controllability vehicle. Also need to pay attention to the regulation gear ratio, It should be placed on small speed. This is done so that the tractor, when performing various works, did 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 complex areas, it is possible to envisage the possibility of rotating, 15 degrees are enough. This is done by the introduction of a swivel system from the UAZ, it is installed in the front of the rear semi-frame. In order not to be the possibility of a larger coup on the hinge plate, the limiter is welded.
As a result, it turns out very practical carwhich is able to ensure the fulfillment of all the needs arising from the conduct of the household. You can cling to the tractor with ease of all sorts of adaptations for plowing of land, trailers for the carriage of goods, haymelines and other devices.Make a mini tractor with their own hands can each, most importantly, stock necessary tool, material and patience. As a result, it turns out a full-fledged multifunctional machine that allows you to fulfill all the owner's economic needs. High passability, ease of use, multifunctionality - these are the advantages that you will receive after mounting the self-made tractor.
Looking at how the unusual mini loader works smartly, it is difficult to believe that this is homemade. A unique iron assistant collected Tyumen from auto parts Alexander Karaman. With his brainchild, the correspondent "Vlukh.ru" met on the shore of the Lake Champions, it is also Lipovaya-2, where work is underway to expand the database for training and conducting winter swimming competitions. Walf-activists of the center " Akvizport-Tyumen.»Help who can. Alexander also brought his mini-loader to speed up and relieve work on the improvement of the territory. At the sight of such a miracle of technology, few people could stay indifferent.
"I live in a private house and already tired of removing the snow in winter, so I decided to collect a mini-loader," Alexander Karaman explained "Vlukh.ru". - Bobcat type loader I can not afford, as well as most private owners. On average, these are 1.5 million rubles. The Chinese mini tractor costs 650-700 thousand rubles, plus still hinged equipment. My loader cost me 150 thousand rubles. I think that it can be done even cheaper, because this is my first experience. "
As it turned out, in order to start designing and creating technically complex mechanisms, it is not necessary to be an engineer - quite desire. Alexander with a specialty welder. Loader he collected in three months. "Golden Hands," friends and cameras on the hole respond about him. Based on the forge of Tyumen morry athletes Alexander, before that, welded the planner complex, which is a complex structure on which children and adults can train.
Alexander told, from which parts he collected a frontal mini-loader. All-wheel drive car, she has two shortened bridges, both were taken from the VAZ "seven". From "Zhiguli" the master borrowed a gearbox.
What is interesting, the frame "is overwhelmed", thanks to which the mini-loader can turn and rely on all four wheels, regardless of the terrain. Thereby creating good permeability and traction effort. Turns are performed as on a large loader with a hydraulic cylinder.
Chinese S. Engine air cooled With a capacity of 13 hp, there is a starter. Hydraulics works from hydraulic pump, pressure is fed to the joystick distributor. One hand can be lifted and lowering the bucket, as well as turn left and right, which is very convenient.
According to Clell, many nodes for their mini-loader he invented himself, some were copied from other inventors who share their experiences on the Internet. Something was improved. So, on the mini-loader there is no gas pedal, only grip and brake. The clutch pedal serves as a gas pedal. You can move from the place with any transmission. The speed is not more than 10 km per hour. Something more without springs and shock absorbers can hardly count on.
The homemade mini-loader in length is 110 cm, so that it can be transported in the trailer on light car. The Tyumen Master is confident that the car can be made even more compact, shorter by 30-40 cm, which will allow it to be more maneuverable.
The next prototype promises to be more technically perfect. However, will it be able to establish in Tyumen at least small-scale production mini-loaders Did the crisis and the exchange rate of the currency? Alexander is skeptical, because now local enterprises are easier to establish a large-sized assembly of imported technology than to introduce domestic developments.
