Example embodiments relate to a combine harvester including a straw chopper having an inlet for unchopped straw, an outlet for chopped straw in an essentially horizontal direction, and a spreader fan, connected downstream of the outlet of the straw chopper and having an essentially horizontal plane of rotation, for spreading the chopped straw over a ground surface. The combine harvester further includes a guide member, which is arranged to deflect at least a part of the stream of chopped straw material to an axial intake of the spreader fan such that the part of chopped straw material meets the blades of the spreader fan in the direction of transport of the chopped straw material through the spreader fan at an acute angle (α) relative to the plane of rotation of the spreader fan. The part of the stream of chopped straw material thereby contributes to the material movement through the spreader fan.
