Not naraduyus its homemade and truly versatile tractor with 40 HP, although the time and effort it took a lot. And most of these costs took the Assembly design, and procurement necessary components and parts (mainly from decommissioned vehicles and agricultural equipment).

As can be seen from the kinematic scheme of the transmission, as the power unit uses the engine from the car “Zaporozhets” with the standard transmission, main transmission, drive axles and flanges. However, the latter had to be put on the axle shaft side. A small trick, but it is possible to get rid of the problems with the mounting of the sprockets, each of which is rigidly bolted to its flange with four bolts M12. Bearings with housings taken from a decommissioned straw walkers combine harvesters “Niva”.
The torque from the axle shafts of the power unit is transmitted to the rear drive wheels of the tractor. Left and right actuators here are exactly the same. There is a first transmission chain (1=1) single-stage reducer with helical gears, allowing four times the slow rotation. Only the leading wheels of the tractor and this speed is not permissible, therefore, in the kinematic scheme of the transmission introduced two (located symmetrically relative to the longitudinal axis) of the chain transmission.
In doing chain PR-15,875 the intermediate shaft, the torque decreases almost three times. Then it is transmitted (PR-19,05, i =3,538) on the driven sprockets of the respective rear wheels of the tractor. The total reduction gear ratio is 39,18. Given that the circumference of the drive wheel of “Zaporozhets”, which is intended for the basic power unit, three times less than the tractor’s wheels, the resulting ratio is equal to 13,06.
Kinematic diagram of the transmission of the tractor-wagon
Kinematic scheme of the transmission of the tractor-wagon:
1 – front wheel (the drive from the rear axle of combine harvester “Beer”, bus 240-406 from a tractor trailer); 2 – power unit (engine car “Zaporozhets” with the gearbox, main gear, axle shafts and modified flanges); 3,5,6 – transmission chain; 4 – reducer with helical gears (i = 4,2 PCs); 7 — rear wheel, leading (from grain drills, bus 240-813); 8 – node rear wheel bearing (from the seeder).

The frame of the tractor (from emergency diesel generator, modified)
The frame of the tractor (from emergency diesel generator, modified):
1 — base (welded construction of channel No. 18, 12 and 10); 2 – (area 75×50, 2); 3 — lower cross member (area 25×25); 4 — layout for the installation of the half shaft of the rear wheel; 5 — the cross-beams (channel № 10); 6— solitaire (2); 7 — bracket of the hitch mechanism implements (roll-formed channel, 2 PCs.).

The view of the engine and the steering gear.
A view of the engine and the steering gear.
The power unit and all transmission units are mounted on a steel frame based on welded construction from emergency diesel generators, familiar rural electricians. Of course, the frame can make yourself, having a good “svarochnik” with a set of electrodes Yes steel sections of required sizes.
The front axle of the tractor is assembled from parts rear axle of the harvester “Niva” with hubs and rims without tires, the last one from a tractor trailer. The bridge is suspended on the axle shaft of the rear axle of the vehicle ZIL-131 and freely swinging, limited shelves channel frame. The steering mechanism of GAZ-51.
As a leading used wheels from decommissioned grain drills together with the wheel hubs and landing slots for them. However, the inner cover hubs that caused the mechanism of the planter, had to be removed, and instead put an asterisk with a number of teeth equal to 46. It is such applied in headers of combine harvesters of yesteryear. For drive chains sprockets the right size you can also pick up from written-off harvesters and other agricultural machinery.
The main hydraulic cylinder from the car “Zaporozhets”. It is fastened by two bolts M8 on the rack with a length of 300 mm from a steel angle 25×25 mm.
The service brakes are mounted on the sprockets of the intermediate shaft. Brake drums (rear wheels from the base car) are attached to star six M14 bolts each. The brake pads are installed with shields in place on the brackets, the latter are welded to the frame. The brake cable.
Machines for soil treatment are fixed on the levers located to the rear of the frame. The number of used agricultural equipment — single-tractor plow, mouldboard three potato beds, the cultivator with seven plows and a harrow, and potato two row.
Among the advantages of my seroquelno compared to other homemade tractors not to mention good traction force, low cost, and lack of turning and other complex operations in its manufacture and maintenance. Make yourself such a mechanical assistant — you will not regret!
