Simplicity in manufacture and maintenance, reliability, versatility— these are the qualities that I wanted to achieve by producing tillers. Now, after two years of operation at the farm, I can say that the goal is achieved:the machine has become an indispensable helper with a set of attachments walk-behind tractor is used For plowing, cultivating, hilling, harrowing, and in winter — to clear Paths of Snow. In the coupler with a single axle cart with a wooden body and driver’s seat, turns the self-propelled chassis carrying up to 200 kg.
Walking tractor frame is welded from steel pipes square and rectangular cross section. Her spars—two-meter segment of a cross section of 42 X 42 X 3 mm with their ends welded to the cross beams with a length of 230 mm and a cross section 30X30X3 mm. Frame is reinforced with a Central crossbar. Beside it, under the spars — welded two of the bridge supports of the segments of the rectangular pipe 45 X 20 X 3 mm.
Support the engine and the fuel tank is bent from thick steel strip U-shaped bracket with a width of 40 mm,

As the power unit used engine chainsaw “Ural MP-5” capacity-5 liters “. Connected to the crankcase bevel gear chainsaw “Friendship”. Through the application installed on the output shaft of the gearbox sprocket Z1 {16 teeth) and chain (pitch 12,7 mm) Torque is transmitted to the sprocket 1-2 input shaft to the gearbox from the motor scooter “Vyatka”.
This arrangement of the units may seem unnecessarily complicated. Indeed, to use the engine of the scooter Assembly from the box would be easier, but I chose this option based on the availability of my parts and assemblies.
