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.

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.
