Abstract: A trailer drive apparatus utilizes a gasoline operated engine carried by a housing supported by a single wheel driven by the output shaft of the engine. The housing is pivotably secured to an upright tubing fastened to a frame. The frame is provided with a ball assembly conventionally used in engaging a trailer hitch apparatus. A strut, of adjustable length, is secured to the upright tube and coupled to a portion of the trailer hitch bar. A handlebar is affixed to the end of a rod passing through the tube thereby permitting the engine housing to be rotated at 360.degree..
