A combine harvester has at least one rotor oriented in the longitudinal direction of the harvester and configured to separate grains and light chaff from a stream of residue material transported to the distal end of the rotor, where said stream is ejected downwards into a chopper housing. The chopper housing has a pair of chopper wheels configured so that the stream of residue material is ejected directly into the area between said chopper wheels, with essentially no residue being allowed to enter the space between the circumference of the wheels and the sidewalls of the chopper housing. The harvester also has a spreader with a pair of laterally placed spreader openings in the chopper housing, preferably with a pair of spreader snouts mounted on said openings.
