Abstract: An agricultural mixer includes a hydraulic drive system. The mixer includes an automatic jam-resolving feature, whereby if an auger becomes jammed, the drive system will cause the auger to rotate in a reverse direction for a period of time to resolve the jam. The hydraulic drive system will maintain a speed of rotation of the auger at a relatively constant rate during mixing while choosing an efficient displacement setting for the hydraulic motor. The auger is maintained at a constant speed during a discharge mode by maintaining the motor in a maximum displacement setting. A clean-out mode is provided wherein the auger is rotated at a maximum speed to aid in cleaning out the last remaining feed mixture in the mixer.

Abstract: A mixer includes a housing having one or more augers therein. The augers are turned so that they lift the material being mixed upwardly. Fixed on the side walls, which include baffles, are one or more deflectors which impart a downward motion on the mixture being mixed so that the mixture is tumbled upwardly by the augers and downwardly by the deflectors.

Abstract: An animal feed mixer includes a housing forming first and second chambers. An upper auger and a lower auger are mounted in one of the chambers and a rotor is mounted in the other of the chambers. The rotor includes a plurality of arm assemblies that are staggered with respect to one another, that overlap one another in length, and that have paddles affixed to the outer ends of radially extending arms.

Abstract: The invention relates to a mixer that includes at least one multi-flighted auger for mixing together materials, especially livestock feed. The multi-flighted auger rotates about a generally vertical axis. The flights include a kicker knife at the bottom and chopper knives around their periphery. The upper surface of the flights may be perpendicular to a shaft about which the auger rotates, or may be concave or slanted generally upwardly to encourage the material being mixed to remain in contact with the auger.

Abstract: A material spreader includes a belt/chain assembly. The belt is mounted within the chamber of the material spreader and the chain remains out of contact with the material during the operation of the device. A sliding barrier is mounted at the rear of the belt, and moves from a forward position adjacent the front of the spreader to a rear position adjacent the rear of the spreader. One form of the hydraulic system utilizes a sensor for built up pressure within independently driven augers. In response to this pressure build up the sliding barrier speed is reduced.
