Abstract
The invention concerns a harvested crop chopper remains-and-distribution arrangement for a combine () with a straw chopper () and an impeller blower () arranged downstream of the straw chopper (), that includes at least one impeller blade () arranged to rotate in a direction of rotation about an axis () for the distribution across a field of the harvested crop remains provided by the straw chopper (). An axially outer region () of the impeller blade () leading in the direction of rotation is curved or angled in the direction of rotation. The axial dimension of the axially outer region () of the impeller blade () increases toward the outside in the radial direction. The impeller blade () is provided with a region () adjacent to the axial outer region () of the impeller blade, whose axial dimension decreases toward the outside in the radial direction and that extends in the radial direction and that is flat or is curved in a concave shape towards the front in the radial direction and is flatter than the outer region ().
