Abstract: The invention is a corner unloader for a warewasher. The corner unloader includes a frame defining a corner having an inlet end and a discharge end; a pivoting carriage mounted within the frame; the carriage comprising at least two spokes and a bracket interconnecting the spokes; a plurality of pusher elements pivotally mounted to the bracket; a drive arm for providing motion to and driving the carriage; such that retraction of the drive arm causes the carriage to rotate in a counterclockwise direction and causes pusher elements to advance any racks received on the carriage from the inlet end in a direction toward the discharge end of the unloader and extension of theorize arm causes the carriage to rotate in a clockwise direction and the pusher elements pivot under the racks, whereby repeatedly extending and retracting of the carriage pushes racks through the unloader from the inlet end to the discharge end.
