摘要 A multi-purpose spreader for use in handling manure, grain, corn or the like which has a self-contained hydraulically driven power unit actuated from a tractor power take off. A first single acting hydraulic cylinder raises and lowers a drip proof end gate at the rear of the spreader and a second double acting multi-stage hydraulic cylinder which is synchronized to operate with the gate opening cylinder pushes an upright discharge gate from the front of the spreader to the rear to discharge material on the floor of the spreader into beaters at the rear of the spreader when the end gate is in raised position. The beaters are rotated by a hydraulic motor in synchronism with actuation of the end gate and discharge gate to throw the material off the rear of the spreader.
