A combine harvester has at its rear end separate chaff and crop residue discharge openings. A chopper is provided for cutting the crop residue into small pieces, and a chaff discharge device serves to disperse the chaff exiting from the chaff discharge opening. The chaff discharge device is movable between a first position, in which chaff can fall to the ground without passing through the chaff discharge device to lie in a string behind the combine harvester, and a second position, in which the chaff passes through the chaff discharge device and is dispersed laterally away from the combine harvester. The chaff discharge device is further movable to a third position in which chaff leaving the chaff discharge device is directed to enter the chopper through an opening that is different from the opening through which the crop residue is admitted into the chopper.
