Abstract
A spreading apparatus for spreading material onto a target area is disclosed. The spreading apparatus includes a container for the material, a discharge unit which discharges the material, a deflector door disposed on a discharge port of the discharge unit, a positioning device which positions the deflector door and a controller configured to control the deflector door so that the deflector door is positioned between a first closed position and a second open position. The material is substantially prevented from exiting through the discharge port when the deflector door is in the first position. The deflector door may further be positioned at a position between the first closed position and second open position to control a distance of the material discharged from the discharge port.
