A forage harvester comprises a header (100) for harvesting crop and providing the crop to a cutter drum (110) of the harvester for processing the crop, and a wear plate (120) positioned in the vicinity of the cutter drum (110) to guide the cut crop towards a discharge section (200) of the harvester. The harvester further comprises a flow generator (300/630) for generating a fluid flow (310/500) along a surface (320) of the wear plate (120) facing the cutter drum (110) or along an inner discharge surface of the discharge section (200), in order to facilitate a transport of the cut crop towards an outlet (240) of the discharge section (200).
