Abstract
An agricultural harvester includes: a chassis; a cleaning system carried by the chassis; a crop material elevator supplied with crop material that has passed through the cleaning system; and an auger supplying the crop material from the cleaning system to the crop material elevator. The auger includes: an auger axle configured to rotate and defining an auger axis of rotation; a first flighting having a first helical direction and configured to be rotated by the auger axle; a second flighting having a second helical direction opposite to the first helical direction, the second flighting configured to be rotated so as to direct crop material conveyed by the first flighting back toward the first flighting; and a thrower connected to the first flighting and the second flighting and configured to convey crop material transversely relative to the auger axis of rotation.
