An axial flow combine having a crop harvesting header including a feeder for cutting a crop and feeding it rearwardly into a threshing and separating mechanism. The mechanism includes a casing for receiving the crop material and a rotor within the casing for threshing and separating grain from the crop material. A plurality of crop material directing vanes is disposed within the casing and cooperate with the rotor in directing the material generally helically along the casing. Means are included for selectively and simultaneously adjusting the position of the vanes to change the rate of movement of the crop material through the casing.

A crop harvesting header for a self-propelled combine. The header includes a 'floating' flexible cutterbar movable vertically relative to the header frame to cut a standing crop (soybeans, for example) close to the ground to minimize crop losses. The cutterbar is connected to a plurality of runner structures pivotally mounted on the header frame. A spring system is operative on the runner structures to resiliently counterbalance the cutterbar. Elongated skids are connected between adjacent pairs of runners to effectively extend along the length of the header. The skids are mounted to permit individual movement of the runners relative to each other as the cutterbar flexes over uneven ground across the harvesting path. The skids are selectively shiftable to vary the cutting height of the cutterbar.
