A trailer hitch clamp is removably fixed to the hitch shaft and is adapted for holding a trailer hitch. The hitch shaft engaging a cover and further provides a fixed steering sprocket coaxial with the hitch shaft. A drive wheel is rotatably mounted on a horizontal axle, which is positioned between the two arms of the frame, and engages a drive sprocket for rotating therewith on the axle. An electric motor is fixed to the frame and provides a driven sprocket interconnected with the drive sprocket by a first drive belt. A drive circuit drives the motor in either a forward or reverse direction. A steering assembly includes a rotatable steering shaft held in a fixed position by the cover and provides a rotatable steering sprocket at one end and a steering arm at the other end.
