Abstract: A system for controlling extension and retraction of trailer landing gear of a trailer, with the landing gear including a shaft which is rotated to retract and extend the landing gear and the trailer further including a source of electricity. The system comprises: an electric motor having an output shaft disposed 90 degrees with respect to a longitudinal axis of the motor; a mounting plate affixable to the trailer landing gear, with the motor affixable to the mounting plate, the mounting plate sized and dimensioned to position the output shaft in axial alignment and adjacent to an end of the landing gear shaft, and to position the motor outboard of the trailer landing gear; and the motor connectable to the source of electricity to rotate and cause retraction or extension of the trailer landing gear.
