Combine harvester with transverse feed drum

A combine harvester includes a separating device that extends in a longitudinal direction of the combine harvester. In front of the separating device, a tangentially disposed feed drum is installed. The feed drum is configured with substantially axially parallel guide plates on a circumference thereof. The substantially axially parallel guide plates bear against the jacket surface of the feed drum via support elements. The support elements extend between adjacent guide plates in the circumferential direction and, extend between the adjacent guide plates in the radial direction across an entire free jacket surface of the feed drum.
