Abstract: An automatic winch drive system (AWDS) adapted to mount a motorized conveyance and designed specifically to raise and lower a spare tire and wheel. The AWDS is adapted to mount a motorized conveyance at the rear portion of same during factory installation or as an after-purchase accessory/enhancement. The principal object includes the following: a power cell, a reversing control switch, an electric gear motor, an adapter, a drive, a gib, threaded fasteners, a limit switch, an alert and a manual redundancy. The redundancy activates the gear motor's rotor, gearbox and drive; it is built into the system to override the automatic setting in the event of an electrical malfunction or power failure. The principal object has a warning mechanism that broadcasts an alert when the winch cable has been deployed; it remains in effect until the spare tire and wheel are returned to their appropriate storage configuration.
