Abstract
A grain harvesting combine has an elevator system for conveying tailings and clean grain. The tailings are conveyed above the grain storage bin where they enter a chute and flow back to the threshing rotor. A window located at the entrance of the chute cooperates with impellers on the threshing rotor to create a strong downdraft to facilitate flow of the tailings. A stuck crop chamber has a trap door that senses when product jams in the elevator and automatically opens to discharge crop if so.
