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. The deflector and a mounting track prevent dispensing material impacting on a user of the spreader, and when the deflector is extended, also prevent dispensing material distributing to the right side of the spreader. 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.
