Our country has always been famous for craftsmen who can make rather complex structures, for example, tractors, from simple and affordable materials. Of course, you are unlikely to succeed in creating ideal home-made tractors right away, but now there is a lot of literature, and you can also 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 errors.
An amateur constructor should pay attention not only to creating a functional model, but also to making homemade tractors attractive in appearance and convenient to operate.
For the frame, a channel is used, of which two spars are made, the front and rear traverses, the frame is made in the form of a trapezoid, the narrow end of which is located in front. For mounting on the frame of various nodes and mechanisms, holes are made in it.
A subframe is attached to the frame, which consists of two racks made of a corner, and after its installation, the engine and all transmission units are mounted on the frame.
Using bolts, shoes are attached from below to the side members, with which the rear axle will be connected . Bushings are welded to attach the hinge to the shoes. This design allows you to mount the hitch to the frame, which is convenient when using a plow. For transport work, a tow bar is attached to the rear cross beam, to which various equipment can cling with the help of a king pin.
In order for the front axle suspension to be articulated and rigid, an eye must be welded. A beam is inserted into it through a special fork, which is bolted to the cross member of the frame and to the front traverses.
When homemade tractors are made, it is advisable to use small power units, for example, from a motorcycle. The engine from Izh-Planet has proven itself well. To ensure good cooling, you can use a casing with a fan from a motorcycle stroller. It is necessary to slightly cut the cooling fins of the cylinder for a more tight connection of all nodes. In order for the tractor to work without a battery, the ignition coil, generator and commutator were taken from the Voskhod motorcycle. A fire extinguisher case is used as a silencer, which is filled with metal filings, and such a device performs its function perfectly.
This tractor uses a transmission from the GAZ-51, a chain transmission, and also uses a gearbox for the power take-off shaft.
As the rear axle, parts from the GAZ-51 and the universal joint from the GAZ-66 are used, and the front axle is taken from the electric lift truck.
When designing the steering parts from GAZ-53 are used, the steering gear reducer is used , as well as the main brake cylinder. For lateral traction - stretching the side trailer of the Izh-Jupiter motorcycle, the tips are taken from the Moskvich 412.
When choosing tires for homemade tractors, it is better to stop on wheels from the GAZ-51, they withstand a greater load than the wheels from cars, but at the same time are quite soft.
Since the tractor has a stiffer suspension, a sprung seat is installed on it for comfortable operation.
Since this tractor will be used in various agricultural work, additional details are provided on it. On the hitch, a mechanical screw drive is used to lower and raise the equipment used. An additional bracket is supplied for attaching the mower.
If you decide to make a mini tractor with your own hands, then there is nothing complicated. It is necessary that you have the desire and, of course, the elementary skills of a car mechanic.
When operating such a tractor, it will be much simpler and more reliable to deliver all attachments to the workplace separately. Thus, you will protect not only yourself, but also all those around you.
