A mounting plate is provided which has a threaded end secured in the bung, and a flange secured at a selected angle to the threaded end. A collapsible propeller and mixing shaft pass into the container through the threaded end and a motor operatively connected to the mixing shaft is secured to the mounting plate around the container opening by spaced bolts which pass through and lock into keyhole slots in the mounting plate. The motor, mixing shaft and propeller are secured at an angle so that the propeller is in a selected quadrant near the axis, and preferably also the bottom, of the container. The apparatus can easily be installed and removed without twisting or tangling the power cord.
