Abstract
A drive system for all-wheel drive vehicles is provided having separate front and rear transaxles powered by a single engine through a power transfer system. The transaxles each include a hydrostatic transmission and an axle, the hydrostatic gearing system within the hydrostatic transmission serving, in conventional manner, to transfer power from the engine to the axle and drive wheel or wheels. Thus, the front and rear transmissions each may include driving shafts, lay shafts, gear wheels, differentials, and/or other drive train entities employed in the art. A single shifting mechanism associated with the gear systems within each hydrostatic transmission is employed to operate the separate hydrostatic transmissions in harmony.
