Crop harvester header for mowing stalk-like crop

A crop harvester header includes a plurality of intake and mowing drums mounted in side-by-side relationship to each other across the width of the header. Located to the rear of the intake and mowing drums for receiving crop delivered to the rear by them are a pair of slope conveyor drums respectively located on opposite sides of a longitudinal center plane of the header and at opposite sides of an inlet passage leading to feed rolls for introducing the crop into a chopper drum of the harvester. The pair of slope conveyor drums are respectively located adjacent an inner pair of the intake and mowing drums that are respectively located on opposite sides of the center plane and located between, and at least nearly along a line of centers of, each slope conveyor drum and an intermediate intake and mowing drum located outwardly of an adjacent inner intake and mowing drum, is a transverse conveying drum having tooth-shaped drivers disposed in overlapping relationship to tooth-shaped drivers of the slope conveyor and intermediate intake and mowing drums.
