A harvesting apparatus for harvesting cereal grains, rice, grains or seeds, is operated as a front, side or rear attachment and has a crop stripper extending over a working width which is generating a rotor air stream, an inclined chute having a first edge facing the crop stripper and a second edge facing away from the crop stripper. The second edge is disposed to lie lower than the first edge facing the crop stripper and is attached between a threshing apparatus and a separation apparatus which extend over the predominant or the entire part of the working width. The harvesting apparatus has a cleaning air channel, wherein air from a fan and the crop stripper rotor air stream flow through the cleaning air channel for cleaning the crop. The cleaning air channel extends over the predominant part or the entirety of the working width.
