Abstract: The invention relates to a wheel drive system incorporating a hydraulic motor of the toothed wheel type. The motor portion comprises a rotating casing and a stationary shaft member. The motor casing is rotatably journalled in a hub member and the casing has a flange to which a ground engaging wheel may be attached. Expanding and contracting chambers are formed by relative movement between a toothed ring member which is fixedly attached to the casing for rotation therewith and surrounds a toothed wheel member, the ring member being rotatable about its own axis and the toothed wheel member is capable of only orbital movement about the ring axis. The casing and shaft member having cooperating fluid passages for feeding and exhausting the expanding and contracting chambers.
