Abstract
An axial flow combine having a foraminous cylindrical cage with a radial inlet through which crop material is fed by a feeder conveyor. The crop material is engaged by a threshing rotor having rasp bars with diagonal flanges tending to move the crop material axially in a direction away from the inlet. Helical ribs on the inside of the cage also urge the crop material in the same axial direction. A crop directing plate at the side of the inlet toward which the incoming crop material is urged forces the crop material to move circumferentially about the interior of the cage and across a substantial portion of the concave which is the same width as the inlet.
