ABSTRACT:
A self-powered device for maneuvering automobile trailers after they are disconnected from the automobile comprises a coupling sleeve for receiving the lower end of a telescopic jack tube on the trailer, which coupling sleeve is mounted between the front caster wheel of the device and the rear driving wheel. The coupling sleeve socket swivels fore and aft but not side to side to facilitate rolling over uneven surfaces while providing lateral stability. The low height of the coupling sleeve permits connection to the trailer while the trailer is still attached to the automobile.
