Abstract
A hydrostatic drive system having valving which disengages power to selected drive wheel motors in response to a sensed lack of traction, while the driven vehicle is in motion. The valving also allows communication of fluid between the inlet port of one drive wheel motor and the outlet port of another, in response to the decoupling of one of the motors in order to prevent an abrupt transition.
