ABSTRACT:
A front wheel assist drive for a vehicle having a rear wheel main drive includes a hydraulic fluid pump. The pump is connected to a hydraulic motor. The motor is connected to an output shaft. An overrunning clutch is interposed between the motor and output shaft for selectively connecting the shaft to the motor when the motor is turning in a first direction. An output shaft is connected to a front wheel for driving the wheel in a first direction via the motor. A control is connected to the motor for preventing the motor from dynamically braking the vehicle when the wheel is driven in a reverse direction through the main drive.
