Abstract
A crop residue chopping and spreading arrangement is described with a straw chopper () and an impeller blower () arranged downstream of the straw chopper (). The impeller blower comprises impeller paddles () that can be set in rotation about a rotational axis () and an end-side cover () arranged directly adjacent to the impeller paddles (). The impeller paddles () receive crop residue in a take-up region from the straw chopper () and discharge it in a discharge region onto a field. The end-side cover () is provided in front of the discharge region, with respect to the direction of rotation of the impeller paddles (), with an opening () through which, during operation, the impeller paddles () take in air and discharge it in the discharge region, wherein this arrangement increases the throwing range of the impeller blower ().
