Abstract
A mechanism for manually and automatically adjusting the front support drum of an endless conveyor within the feederhouse of an agricultural combine. The front drum is rotatably affixed to the remote end of a pivot arm that is pivotably affixed to the side sheet of the feederhouse. The relative position of the drum to the floor of the feederhouse is manually adjustable by manipulation of a cam that moves the pivot arm toward and away from the floor to preset positions. In combination with the adjustment mechanism, is a pivot mounting for the pivot arm that allows the drum to move upwardly and rearwardly when a bulk or lump of crop material enters the opening between the drum and the floor, thereby preventing damage to the components of the feederhouse.
