Abstract: A cutting system for a combine harvester has a three-part frame with frame parts articulately joined with each other. A cutter bar, a reel, a central belt conveyor system, and lateral belt conveyor systems for discharging the cut stalk material are supported by the frame. The lateral belt conveyor systems move transversely to the travel direction towards the central belt conveyor system. The central belt conveyor system moves contrary to the travel direction. To prevent accumulation of crop material near the rear wall of the lateral belt conveyor systems, a three-part screw conveyor is arranged near the rear wall and extends across the operating width of the cutting system such that the length of the screw conveyor parts corresponds at least approximately to the width of the frame parts. The screw conveyor parts are powered by a joint drive. Adjacent screw conveyor parts are mutually connected by universal joints.
