Abstract
The cutter mixer has a mixer tub with side walls and a floor. The floor includes a primary floor portion at a lower elevation. At least one secondary floor is positioned vertically above the primary floor portion. A primary vertical spindle is journaled in the center of the primary floor. A secondary vertical spindle is journaled on the secondary floor. Auger flighting is attached to the primary spindle. Auger flighting is also attached to the secondary spindle. The flighting decreases in width from the bottom to the top of each spindle. The bottom of the flighting on the primary spindle sweeps over substantially all the primary floor. The flighting on the secondary spindle overlaps the flighting on the primary spindle and sweeps fodder from the secondary floor to the primary floor. The augers are driven to cut and mix fodder and discharge fodder from the primary floor.
