One of the wheeled tractors use effectiveness essential indicators in agricultural production is the indicator of their traction and grip qualities, due primarily to the interaction of the driving wheels with the rolling surface on different soil backgrounds and the slip coefficient. As the result of the wheel propellers interaction with the soil, the latter one is compacted and intensively destroyed. Uneven soil density increases traction resistance and increases the energy consumption for the machine-tractor unit movement (MTU). The possibility of the most effective reduction of hook load fluctuations corresponding to an intensive increase in slipping is provided by the elastic pneumohydraulic element, which has the ability to regulate optimal parameters in a wide range of elastic properties.
