Abstract: Wheel and axle assembly for a small vehicle such as a riding lawnmower which includes a frame and an engine mounted upon the frame, the assembly comprising an axle having opposite first and second ends journalled mounted upon the frame for rotation and drivingly connected to the output of the engine conventionally through a transmission. First and second wheels are provided for mounting, respectively, on the first and second axle ends. The first wheel is rigidly connected to the first axle end for rotation with the axle such as by pinning or by a key. A torque-limited driving connection is provided between the second wheel and the second axle end, the torque-limited driving connection permitting relative rotation between the second wheel and axle when a predetermined torque level is exceeded. This torque-limited device may include a frictional drive connection between the second wheel and the axle. The second wheel may include a rim housing journalled mounted on the second axle end for rotation relative to the axle, and a friction clutch for drivingly connecting the rim housing to the axle. The clutch may include a clutch plate mounted on the second axle end for rotation with the axle and friction pads for engaging the plate, the pads being carried by the rim housing.
