ABSTRACT:
A hydraulic wheel motor and pump are provided for use with a motor vehicle having a pair of mechanically driven wheels and a pair of non-mechanically driven wheels. The hydraulic pumps cooperate with the mechanically driven wheels, and the hydraulic motors are coupled to the non-mechanically driven wheels. The pumps and motors are diagonally connected to one another to create a four wheel drive vehicle.
