A combine harvester has a husk discharge device mounted downstream from a sieving unit, and a blower mounted in a housing having at least one husk discharge opening, and a straw chopping device, which is located downstream from a straw shaking device and the husk discharge device and which has a rotary cutter mounted in a housing to chop the straw, the housing having an inlet for the unchopped straw and an outlet for the chopped straw. A guide means is located upstream of the straw chopping device, the guide means being displaceable between a first position for closing the inlet so as to effect bypassing of the straw chopping device and allowing deposition of the unchopped straw in the form of strings, and a second position in which is exposed the inlet to allow chopping of straw. A spreading device for spreading of the chopped straw received from the straw chopping device is connected to the outlet thereof and is formed with spreader wings. The husk discharge opening is arranged to be directed towards the spreading device, allowing husks to be blown into the device and spreading of the husks over the ground with the aid of the spreader wings. |
