An improvement for the header of a cereal grain harvesting combine is disclosed. A first version of disclosure provides rollers driving two or more chain loops which in turn carry a plurality of slats which propel cut crop material rearwardly. A second version of the disclosure includes rollers carrying an endless loop of canvass fabric. The canvass fabric is preferably covered with a rubberized coating, which protects against water damage and better frictionally engages the cut crop material. The fabric supports a plurality of slats which propel cut crop material rearwardly. A third version of the disclosure includes three rotating tubes, each having a square cross-section, that aid in more rapidly and more evenly inputting cut crop material. The tubes carry elongate felt strips which frictionally engage the cut crop, moving it rearwardly. The tubes tend to move the cut crop that would otherwise be too low to be engaged by the rotating spikes used between the left and right augers. The shape of the tubes, having a square cross-section, tends to bounce the cut crop vertically up and down, resulting in the rotating spikes carried by the reel of the header being better able to contact the crop, and thrust it backwardly, into the combine.
