Abstract
An unloading conveyor apparatus and system for an agricultural harvester including a spout controllably directable for enabling distributing grain in a desired manner within a region of a receiving storage container, or a transporting truck, wagon, or other vehicle, and configurable as a closure for the conveyor for preventing entry of contaminants and the like. The spout can advantageously extend both the distance and range of variability of grain delivery location, and the free end of the spout can include a cover for improving grain delivery accuracy and wind resistance, and a break open feature to prevent damage. The spout can also be rotatable laterally about the end of the conveyor.
