The header is equipped with a crop converging structure including right- and left-hand drums or cages respectively mounted to the tops of right- and left-hand cutter discs respectively at opposite ends of the cutterbar, and further including right- and left-hand crop guiding or directing structures respectively disposed for guiding crop from forward locations of the drums or cages over the cutter discs respectively adjacent the end cutter discs and toward the crop conditioner. 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
