  • Patent number: 5860604
    Abstract: A motorized spreader for dispersing granular and other material, such as fertilizer, seed, and salt, or the like, provides improved uniform control of the flow of the material from the spreader. The motorized spreader includes a frame and drive train supporting the frame. A hopper for holding granular material is also supported on the frame and includes a dispensing opening for directing the flow of granular material from the hopper onto the ground. An agitator is positioned in the hopper for urging the granular material in the hopper toward the dispensing opening so that the flow of the granular material from the hopper is controlled. The drive train includes first and second wheels, with each wheel including an axle. A differential drivingly couples the axles of the wheels together and includes a first drive sprocket and a second drive sprocket, the first drive sprocket coupling to a motor to drive the motorized spreader at a ground speed.
