ABSTRACT:
A mobile spreader unit comprises a tractor and a detachable hopper. The latter is defined by tapering front and rear walls and has a breadth permitting it to fit in between the rear wheels of the tractor. There is an elongate spreader opening in the bottom of the hopper, and an agitator adjacent to the mechanism driven by a roller to be brought into contact with one of the rear wheels of the tractor. Pivots at the front wall of the hopper are attachable to brackets at the tractor, and are located so the point of gravity of the hopper tends to tilt it away from the tractor. In its furthermost tilted position the rear wall will be substantially parallel to the ground, and the hopper may then be used to scoop up particulate material to be spread. A pressure fluid actuator raises the hopper to an upright position, in which finally the roller contacts the rear wheel of the tractor and drives the agitator.
