Abstract: A modular spreader system is provided. The spreader may include a conveyor system defining a frame, a hopper and, a method of attaching the hopper to the frame and for detaching the hopper from the frame. A hydraulic unit may be provided to provide power to the conveyor belt. The hydraulic unit may easily be replaced with an engine. The spreader system may also have a spinner system that can be easily swung out of the way so that the spreader material can be emptied without need to be processed through the spinner system.
