Abstract
A threshing unit including a header having a stripping unit for stripping the grain from the stalks as the unit moves in the field. The threshing unit has height control to accurately position the stripping units at the heights of the heads of grain on the stalk. The grain head is positioned by air flow (for stripping) and the grains is carried into a cleaning unit and then into a combination re-thresher cleaner unit by air flow and centrifugal force. The cleaning is done by air flow and the transport of the grain to an attached or mobile container is accomplished by air flow.
