Abstract
A draper header has an endless belt conveyor supported on two arms that pivot with respect to the frame of the draper header. Both ends of the conveyor belt are supported on the arms such that the ends of the conveyor belt can rotate about respective generally vertical axes to thereby reduce uneven tension across the fore and aft width of the conveyor belt and reduce wear on the conveyor belt.
