Abstract of the Disclosure An improved drive assembly includes a gerotor-type hydraulic motor having a housing connected to a frame. An output member is rotatably mounted on a hollow spindle which is integrally formed with the motor housing. Operation of the motor rotates an input shaft which is disposed within the spindle and is connected with the output member through a gear arrangement. In order to tend to minimize the axial extent of the drive assembly, the gear arrange- ment is located inwardly of an outer end of the spindle. The gear arrangement includes a central or sun gear which is disposed with- in the spindle. A plurality of idler gears extend through openings formed in the spindle into engagement with the central gear. These idler gears meshingly engage a ring gear which is fixedly connected with the output member. The gerotor-type hydraulic motor includes a wobble shaft which is connected with the input shaft to the central gear by a coupling member. A stop member is movable in the spindle to disengage the input shaft from the central gear to deactivate the drive assembly.
