Abstract
A dual conveyor assembly for a windrower includes upper and lower conveyors. Each conveyor includes an endless conveyor element and rotatable supports spaced along a longitudinal conveyor path and entrained by the endless conveyor element. The endless conveyor elements define vertically spaced opposed runs that define the longitudinal conveyor path therebetween. The opposed runs are operable to be driven together to move a flow of severed plant material along the path. At least one of the opposed runs is shiftable relative to the other opposed run in an upright direction, while the runs are driven together, such that the opposed runs remain in moving engagement with the flow of severed plant material as the amount of severed plant material passing between the opposed runs varies.
