Abstract
A rotary combine having axially extending threshing rotor and coacting concave positioned to receive crop material to be threshed from auger means on the forward end of the rotor, and an elevator which extends upward and rearward from a header to the auger means delivers the crop material to an upwardly and rearwardly extending feed plate which guides the crop material upwardly in an undershot manner to said auger means. Several embodiments of a grain trapping and back-flow retarding plate are associated adjustably with said feed plate to permit discharge of threshed crop material and prevent tendencies for the material being fed upward along the feed plate to slide back down the same toward the elevator.
