Abstract
An agricultural harvester includes a chassis; at least one ground engaging traction member connected to the chassis; a cleaning system held by the chassis and configured to clean crop material; and an elevator supplied with the crop material cleaned by the cleaning system. The elevator includes a housing having a crop material inlet that receives the crop material, a boot portion that forms a bottom of the housing, an air inlet and an air outlet; a plurality of paddles configured to convey the crop material through the housing and away from the boot portion in a generally vertical direction; and a blower configured to produce a pressurized air stream through the air inlet that expels loose crop material into the air outlet as the crop material is conveyed away from the boot portion.
