Abstract: A method and device for harvesting grain crops is provided. A threshing method includes separating grain from harvested material, which is fed to a threshing phase after a gathering process taking place against a direction of working travel. During threshing, the harvested material is processed as the respective grain crops and admixtures in the form of straw and chaff such that essential, dischargeable admixtures are separated from the grain crops, and these, in the form of a mixture with chaff or similar fine particles, are fed as a grain/chaff stream to a final cleaning. The grains free of these residual admixtures are subsequently collected as grain crops. During at least one feed phase preceding the final cleaning, a transport movement is imparted to the at least one grain/chaff stream with the transport movement having a component in a vertical direction and a component in the direction of working travel.
