Abstract: A broadcast spreader with a movable deflector is disclosed. The spreader distributes particulate material by a rotating plate which when operating, always impacts material on the deflector.

In this way, lawns which abut a driveway or a flowerbed may have material distributed on them without also depositing material on the driveway or flowerbed. Further, the deflector is integral with a port closure panel which automatically reduces, in a proportional manner, the flow of particulate material as the deflector is extended.

The material discharge rate and discharge pattern are controllable by a slide gate and interchangeable cover plates which vary the size of the discharge opening. The impeller and bin sweep assembly may be driven by an internal motor or from the towing vehicle by a power take-off drive.

Abstract: A spreader particularly adapted for manual operation over a residential lawn includes a one-piece hopper made of corrosion resistant material. Lugged wheels connect with a shaft which is rotatively carried by and extends through a lower part of the hopper. On the shaft inside the hopper is an agitator bar having outward extending projections. The bar projections align with a series of slots in a rear wall of the hopper for a discharge of material in the hopper to the ground below. To regulate this discharge a movable gate is positioned on an outer side of the hopper slots. Gate movement is effected by a control bar carried in a flow control housing of a handle assembly having an extension attached to the hopper. The degree of gate movement, which affects the size of the slot openings, is regulated by a position of a stop operatively connected to a rotatable dial in the flow control housing.
