Abstract
A grain cleaning system for use in an agricultural combine harvester comprises a return pan, a chaffer, and a grain chute. The return pan is arranged to reciprocate in a fore-aft manner to advance crop material forwardly and comprises openings allowing grain to fall from the return pan through the openings. The chaffer is arranged to reciprocate in a fore-aft manner to advance crop material rearwardly and underlies the return pan. The grain chute is positioned in communication with one or more openings of the openings in the return pan and in communication with the chaffer to guide grain received from the one or more openings to the chaffer in a manner that bypasses material-other-than-grain (MOG) advanced rearwardly by the chaffer. An agricultural combine harvester comprising a grain cleaning system with a grain chute is disclosed.
