  • Patent number: 4867381
    Abstract: A broadcast spreader which includes a storage hopper and a spinning broadcast plate for distributing materials dropped from the hopper. A valve controls the flow of material to the broadcast plate, and is operated by a dual shaft and linkage. The two shafts are connected by a biasing member which allows a squeezable actuator lever to be fully retracted regardless of the dial setting. The spreader may also include a diffuser positioned between the valve and plate to direct the material towards a preselected area of the broadcast plate. The spreader may also include a readily adjustable means to prevent discharge of material in selected direction. The spreader may also include means for restricting the rate of flow of material from the hopper to the broadcast plate for a selected setting of the valve.
