An agricultural combine has a variable displacement pump (202) connected to four drive motors (112, 114, 120, 122) that drive four wheels (108, 110, 116, 118). An electronic controller (214) monitors the speed of each wheel and reduces the torque of the motor that drives the wheel when the wheel slips. The controller (214) reduces the torque by reducing the specific displacement of the motor driving the slipping wheel. Once the wheel has ceased slipping, the controller (214) increases the specific displacement of the motor back to its original displacement. |
