An agricultural harvesting machine for removing and separating grain from harvested crop has a threshing zone and at least one separation zone for separating the grain. The axial separating rotor is at least partially encased by a separating housing having a plurality of sections. At least one of the sections is displaceable in the axial direction of the at least one axial separating rotor to increase the opening and ensure separation when a correspondingly large proportion of grain are in the outer region of the rotating crop stream and the proportion of admixtures is small.
