To make a comparison of different tractors we must use comparative indicators. For estimation of wheel slippage such indicator is tractor weight utilization coefficient for adhesion of driving wheels. The dependencies of wheel slippage on the traction force and weight utilization coefficient of tractors are overviewed. The equations of weight utilization coefficient g ϕ which determinated its dependencies on traction force Ftr, rolling resistant coefficient f of aggregate, working speed v, acceleration a on mass of trailer and tractor mp, mt and its proportion mp/mt. Presented results of experimental research of acceleration and constant speed regimes. Dependencies of adhesion on slippage of diving wheels and slippage on traction force and weight utilisation coefficient of tractor−trailer aggregate.
