An apparatus providing rotational power to the crank shaft actuating the lowering and raising of legs for supporting a load bearing vehicle. The apparatus includes a means for providing rotational force to the crank shaft comprising a battery powered motorized drill having a drive shaft having a plurality of rotational directions, and a motor housing. Also included is a crank shaft coupler adapted for removable attachment to the crank shaft, comprising an adaptor end having a non-round cross-section, and an attachment end defining a cavity snugly accepting the crank shaft and including a pair of apertures aligned with a transverse bore through the crank shaft through which a lock pin is inserted. Also included is a drive shaft coupler for coupling said drive shaft to said crank shaft coupler, comprising a shank end tightly accepted within the chuck of said drill, and a coupler end defining a cavity snugly accepting said adaptor end having a non-round cross-section; also a means for preventing rotation of said means for providing rotational force to the crank shaft comprising a bridge between said motor housing and the load bearing vehicle, said housing including at least one lateral handle having a distal end supporting a bridge arm for contacting the load bearing vehicle and preventing rotation of said drill.
