Claim:
A cutter mixer for cutting and mixing rations for livestock comprising: a tub having a continuous side wall, a floor attached to the continuous side wall and including a horizontal primary floor portion and at least one horizontal secondary floor portion at a higher elevation than the horizontal primary floor portion; a primary spindle journaled on the horizontal primary floor portion for rotation about a vertical primary spindle axis; a primary auger flighting secured to the primary spindle and having a primary leading bottom edge that extends horizontally outward from the primary spindle to sweep a circular portion of the horizontal primary floor portion with a primary auger bottom radius, a primary top discharge edge, and wherein a radial flighting width of the primary auger flighting decreases from the primary leading bottom edge to the primary top discharge edge; at least one secondary spindle journaled on the at least one horizontal secondary floor portion for rotation about a vertical secondary spindle axis of the at least one secondary spindle; a secondary auger flighting secured to the at least one secondary spindle and having a secondary leading bottom edge that extends horizontally outward from the at least one secondary spindle to sweep a portion of a circle with a secondary auger bottom radius, a secondary top discharge edge, and wherein a radial secondary flighting width of the secondary auger flighting decreases from the secondary leading bottom edge to the secondary top discharge edge; and wherein the horizontal distance from the vertical primary spindle axis to the vertical secondary spindle axis is less than the sum of the primary auger bottom radius plus the secondary auger bottom radius.
