Our country has always been famous for folk craftsmen, who from simple and accessible materials can make quite complex designs, for example, tractors. Of course, you will not be able to create ideal self-made tractors at once, but now there is a lot of literature, and you can find a variety of useful information on the Internet.
In this article we will look at an example of how to make a mini tractor with your own hands and point out many of the nuances of this work. Using this information, you can avoid many mistakes.

The frame is joined by a subframe, which consists of two racks made of a corner, and after its installation on the frame, the engine and all the transmission units are mounted.
Using bolts, from below, the shoes are attached to the spars, with the help of which the rear axle will be attached . To attach the sample to the shoes are welded bushings. This design allows you to attach the hinge to the frame, which is convenient when using a plow. For transport operations, a towbar is attached to the trailing arm, to which various equipment can be attached using the king pin.
In order to suspension of the front axle was hinged and rigid, it is necessary to weld the eyelet. In it through a special fork, which is bolted to the crossmember of the frame and the front cross beam is inserted beam.
When self-made tractors are manufactured, it is advisable to use small power units, for example, from a motorcycle. Well-proven engine from the Izh-Planet. To ensure good cooling, you can use a fan casing with a motorized wheelchair. It is necessary to slightly cut the cooling fins of the cylinder for a more dense joining of all the units. In order for the tractor to work without a battery, the ignition coil, generator and commutator are taken from the "Voskhod" motorcycle. As a muffler, a fire extinguisher body is used, which is filled with metal filings, and such a device performs its function perfectly.
