The invention refers to tractor and agricultural machine engineering The vehicle contains a frame onto which there are installed an engine, a cabin, a freight platform, a hydraulic lift system for the agricultural units, a hydrotransmission coupled to the engine and including hydraulic pumps and hydraulic motors for pneumatic rollers driving, a moving system consisting of the driving and supporting pneumatic rollers, crawler belt sets of different length. The pneumatic rollers are articulated to the frame by L-shaped levers and are turned in the frame longitudinal direction by hydraulic or helical devices.The result consists in the possibility of changing the vehicle centre of gravity, in decreasing the ground unit pressure, in cross-country capability increasing.Claims: 3Fig.: 3 |
