Claim:
A mixer attachment for use with a skid steer, the mixer attachment comprising: a mixing tub including a circumferential wall extending between a floor and a rim to define an interior compartment for holding a quantity of material, wherein at least a portion of the circumferential wall has a flat portion extending substantially between the floor to the rim; an auger extending into the interior compartment through the floor for mixing the material within the interior compartment, wherein the auger includes one or more knives for cutting the material in the interior compartment; a hydraulic drive unit configured to rotate the auger, wherein the hydraulic drive unit is connectable to one or more hydraulic connections on the skid steer; an attachment assembly configured to attach the mixing tub to the skid steer; one or more material retarders extending into the interior compartment to impede movement of the material within the interior compartment; a discharge chute movable between an open position that allows discharge of material from the interior compartment and a closed position that prevents discharge of the material within the interior compartment; wherein the mixing tub is movable between a scooping position and a mixing position; wherein the mixing tub is in an approximately horizontal position in the scooping position such that a leading edge of the flat portion is a scooping surface for directing material into the interior compartment of the mixing tub; and wherein the mixing tub is in an approximately vertical position in the mixing position such that rotation of the auger mixes material in the interior compartment of the mixing tub.
