The vehicle is made according to the scheme proven by the tractor “Kirovets”. He has the same “breaking” the frame and drive on both bridges. What gives? First, the permeability. Frame, continuously curving, as if tracking the terrain. All four wheels are constantly in contact with the surface. This eliminates the overload of individual wheels and slip them on uneven ground and secondly, the maneuverability. The hinged frame is sensitive to even the slight deflection of the steering wheel and allows you to turn almost on the spot. Thirdly, constructive simplicity. In this scheme, you can use exactly the same front and rear axles. Simple turns and the engine mount.
