摘要： A material spreader which is adapted to be towed behind a tractor includes a chassis mounted on at least one pair of wheels positioned toward its rear. A box for transporting and dispensing materials is pivotable from a horizontal position to a substantially vertical position and is provided with a rotatably driven beater mounted to its rear. The interior of the box is devoid of any material moving mechanism except for the beater. A vertical support member extends upwardly from each side of the chassis adjacent to the pair of wheels. Each vertical support member is provided with a pivot point adjacent to its upper end for pivotally supporting the box at an elevated location above the rear axle. The box is pivotally supported at a location spaced forwardly from its rear a distance at least equal to the height of the box. The beater and a hydraulic cylinder for raising the box is adapted to be coupled to the hydraulic system of a towing tractor.
