A self-made tractor with a broken frame. How to make a self-made tractor

Tractors with a broken frame attract the attention of many owners who are engaged in the topic of creating machinery for the needs of their farmstead. And although you can buy it in almost any specialized store, creating a self-made device will not only be useful, but even fun. And about how to make a self-made tractor with a breaking frame, our today's article will tell you.

Drawings for performance of works

Any process of manufacturing some kind of equipment or design (even the most primitive stool) is impossible without creating a specific drawing. And if in the case of the same stool you can think of her sketch in your mind (but still you will end up with a not very even detail), then in the case of a tractor you have to draw a drawing without fail. By its design, this technique is a whole complex of complex technical details, and remember about each of them, probably only the computer can. In addition, by focusing on the created drawing, you will significantly shorten the time of the executed works. If you have all the basic elements and assemblies, be sure to consider their relative position on paper. Including it is necessary to include in the drawing and the place for the driver and the location of the checkpoint.

Where to build?

Doing a self-made tractor with a breaking frame, pay attention to the fact that you must have not only a drawing, but also a list of equipment and parts that you need to put together somewhere together. First of all, think about where exactly you will create a tractor. Since the time for performing these works can be measured in weeks, pay attention to the fact that the room had a roof. This is necessary in order that water does not fall into the fundamentally important details of technology (and simply to ensure that the sun is not much baked in the afternoon head). If this is a private house, consider also that all the tools and mechanisms you have acquired are reliably hidden from prying eyes. Note that the room has at least one outlet (so that when working with a welding machine, do not lay out the extension each day). In principle, the most suitable place for assembling the tractor can serve as a garage. It is in it that we will collect a tractor with a breaking frame.

Engine and transmission installation - way number 1

Concerning the engine, gearbox and details of the running system, we note that it is best to take all these units from one particular vehicle. Oka can come here. Or, to make the design as cheap and affordable as possible, purchase the old "Penny" or "Six". You can also take details from the "Moskvich". From it, "with meat," take the engine, gearbox and the entire suspension, including the beam, bridges and wheels (fit and 13-inch, but for field works need a disk with a diameter of not less than 18 '). Rama will be homemade. We will produce it from a 60 mm metal channel. Here we need to apply a welding machine (preferably semi-automatic, so that the work is quick and of good quality) and several dozen packages of electrodes.

Since the tractor and passenger car are slightly different in design, pay attention to the rear axle. Here we will need to shorten its semi-axes to the required length. It is quite simple to do this - just use a simple lathe. If possible, immediately select the gear ratio of the differential gear .

Small tricks how to save money

The most common method is when a motor, gearbox, "distributor" and clutch are installed on a tractor-homemade with a breaking frame. And all this is extracted from one machine. That is why it is best to buy an old "Zhigul" or "Moskvich" for works, since the costs in this case will be minimal (no more than 30-40 thousand rubles). Moreover, after doing all the necessary work, you can sell the car body and everything else on spare parts. In addition, you can place an ad for the sale of documents. But to bypass the long and expensive registration of a car in the SAI, it is best to just buy a car without documents. It costs less, and there is no need to make out a car in the traffic police, if it will be used as a "donor" for our tractor.

Engine and transmission installation - way number 2

You can also make a self-made tractor from a motoblock, but it will already turn out a mini-tractor, less powerful and productive in its characteristics. When choosing an engine, pay special attention to motors such as "UD-2" and "UD-4". They are most often used as power plants on self-made tractors. In addition, the forums are actively discussing the methods of installing ICE brand "M-67". Many of those who already use this motor say that such self-made tractors with a breaking frame will be very unpretentious in maintenance, since the resource of the M-67 is the highest in comparison with all the rest.

As for the gearbox, when using the M-67 engine , you should choose a gearbox with an increased number of gear ratios. This is to ensure that the tractor has the most appropriate tractive effort on the wheels. It is also advisable to take care of the cooling system, since the motor is not that small in size, and therefore, it will very often overheat with high performance. To eliminate the risk of overheating the system, put the fan with the guiding casing on the crankshaft sock. You can also install a two-section copper radiator. But as practice shows, the fan is quite able to cope with its task. It should be noted that when installing a cooling system, you will need to make an additional adapter, so before planning for work, plan for the system a separate drawing.

Swivel connection technology

Since we are making a self-made tractor with a breaking frame, special attention should be paid to the junction of its two parts. As a hinge joint, it is possible to use the cardan shaft of the main gear from the truck - GAZ-51, 52 or 53 (the model is not important, since the cardan construction is similar to them). When designing the steering, it is best to use hydraulic cylinders. Such a self-made tractor with a breaking frame is much easier to control, especially during plowing.

Gear Ratios

Now about what kind of gear ratio you need to pick up for a self-made tractor. Choose these values so that when plowing at speeds of about 1900-2000 per minute, the speed of the device does not exceed the mark of 3-3.5 kilometers per hour (it will not be necessary to drive a tractor with a speed of 70 kilometers per hour on the "Zhigulev" motor hour!). Pay special attention to tractive effort. One ploughshare must be provided from 196 to 300 kgf (depending on the density of the soil). To make speed more simply does not make sense, since the tractor starts to move unsteadily because of the small curb weight.

Conclusion

So, we found out all the ways and options for assembling a self-made tractor. It remains to wish you much enthusiasm, patience and good luck in your work!
