Abstract
A choke plate or damper is removably mounted in the bottom of the broadcast spreader hopper. The choke plate is formed with three apertures, each of which is surrounded by a boss which, with the choke plate in an operative position, projects through a material discharge outlet in the hopper bottom for sliding engagement with a shutter plate slidably mounted on a rear underside portion of the hopper. A deflector is slidably mounted on a forward underside portion of the hopper and is formed with a rearwardly projecting and downwardly inclined portion that, as the deflector is adjusted, moves between positions of greater and lesser interposition between the hopper outlet and a rotary impeller disposed therebelow.
