Abstract: A combine harvester is disclosed, including a separating device for separating grain and straw and a shredding device downstream from the separating device for shredding a straw portion discharged from the separating device. The shredding device comprises a chopping rotor which is rotationally driven about an axis oriented transversely to an infeed direction of the portion of straw into the shredding device, and the rotary movement of which generates an air flow directed away from the chopping rotor. The rotary movement is opposite the infeed direction on a part of the circumference of the chopping rotor. Further, the infeed direction of the straw portion into the shredding device is regulated by at least one structure, such as an adjustable crop guide plate, in such a way that the air flow does not counteract the infeed of the straw portion into the shredding device.

Abstract: A self-propelling combine and a method for operating a self-propelling combine are disclosed. The combine includes an axial spreader, which generates a residual flow of material and supplies the residual flow of material to a downstream distribution device that discharges the residual flow of material from the combine. The axial separator in the end-side material delivery region has at least one guide element that may be moved by an actuator, thereby affecting a distribution of the exiting residual flow of material over the supply width of the distribution device. The distribution of the residual flow of material is detected by at least one sensor unit, and when a deviation from a target distribution is detected, the guide element is adjusted. A control device receives and uses a signal representing a side wind used to automatically adjust of the at least one guide element.
