Zusammenfassung:	This is a device for use in operating a trailer landing gear drive mechanism. The device comprises: an elongated, rigid, cylindrical body having a closed end portion which is coupleable to a rotatable drive shaft of a drive means, and an open end portion which is adapted to releasably grip the end of a crank shaft of a mechanical landing gear drive mechanism. When the drive shaft of the drive means rotates, the device rotates, causing the crank shaft of the mechanical landing gear drive mechanism to rotate, thus effecting the raising or lowering of one or more landing gear legs of a vehicle trailer. The open end of the device comprises at least one slot, which is adapted to releasably grip the end of the crank shaft. There are preferably two identical "T" shaped slots on the open end portion so that the drive speed of the landing gear drive mechanism can be selected. The closed end of the device preferably has a threaded hole which is coupleable to the rotatable drive means. This device provides semi-trailer truck owners and operators with a portable, inexpensive, quick, and efficient way to raise and lower the landing gear of trailers, with virtually no modifications to the trailer.
