Abstract
A broadcast spreader includes a directional control assembly that defines a pathway for granular material from a hopper through a discharge port and onto a rotating fan. The directional control assembly includes a first plate that is secured to and adapted for slidable movement with respect to the hopper. The first plate defines an opening therethrough that is substantially in registry with but smaller than the discharge port, thus serving to define a pathway for the granular material from the hopper through the discharge port and onto the fan. The directional control assembly further includes a second plate secured to and adapted for slidable movement with respect to the hopper and the first plate. Movement of the second plate relative to the first plate selectively opens or closes the pathway for the granular material from the hopper through the discharge port and onto the fan.
