Right- and left-hand transverse wall or bulkhead structures extend upwardly from a transverse stiffener member at the rear of the cutterbar and air inlet openings are provided in each of the transverse walls in order that at least the endmost cutter discs are in communication with an adequate source of air permitting them to create an airstream for sufficient for aiding in conveying crop to the crop conditioner
