Abstract

A combine harvester operates with an axial separating device for separating a crop flow picked up by the combine harvester into a plurality of partial flows. A partial flow composed of grain and non-grain components is fed by a separation surface of the axial separating device to a cleaning unit disposed downstream. The axial separating device is configured to manipulate a local concentration gradient of the partial flow that is output by the axial separating device caused by a tilt of the combine harvester. The extent of the manipulation is controlled individually depending on the tilt of the combine harvester.
