A combine harvester includes a device for discharging husks, the husk discharging device having at least one fan rotatably mounted in a fan casing, the fan casing having at least one husk discharge opening, a device for chopping straw arranged downstream of the husk discharging device, the straw chopping device having a rotating cutting rotor in a rotor casing for chopping straw, the rotor casing having an inlet for unchopped straw and an outlet for chopped straw, and a control device arranged between the husk discharging device and the straw chopping device, the control device being movable between a first position in which the control device closes the inlet of the rotor to bypass the straw chopping device and a second position in which the inlet of the rotor is open to allow chopping of the straw. The husk discharge opening in the fan casing is shiftable between a first position in which husks are permitted to be spread over a substrate, and a second position in which the husks are permitted to mix with unchopped straw.
