Abstract
A system for discharging residue from an agricultural combine to a ground surface. The system including a spreader operatively connected to a rear end of the agricultural combine. The spreader having one or more impellers each having an axis of rotation and a housing. The impellers are operatively connected to the housing for rotating therein. The housing has an inlet for receiving a flow of residue, an outlet configured about a lateral side of the housing for discharging the flow of residue, and one or more residue flow distributors each pivotably movable in a direction generally parallel with the axis of rotation. Each flow distributor is configured to guide the discharged flow of residue sidewardly away from the spreader to the ground surface. The rotation of the one or more impellers discharge a flow of residue received through the inlet out through the outlet.
