A method and device for automatically raising and lowering a large and/or heavy object, for example an icehouse, comprising a body having a first cylindrical end configured for insertion into a chuck of a portable drill and a second opposing body end configured for connection with a winch shaft wherein activating the portable drill will rotate the first and second ends and thus rotate the winch shaft to raise or lower an icehouse. The second end is adapted with a substantially flat outer facing surface having an integral cavity therein. The cavity is machined for engagement with the winch shaft and to efficiently transfer torque from the drill to the winch device for winding up or letting out a winch cable and thus raising or lower a large object connected to the winch system.
