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. During use an operator holds a handle bar of the handle assembly while compressing the control bar until it engages the stop. This control bar action moves the gate to selectively uncover the hopper slots allowing material in the hopper to discharge. Material flow through the hopper slots is enhanced by rotation of the agitator bar and connecting wheels as the wheels roll over the ground below.
