摘要：
The invention concerns a harvested crop residue chopper and distribution arrangement for a combine (10) with a straw chopper (60) with a rotor (74) that can be brought into rotation about a horizontal axis (98) with chopper blades (76) fastened thereto that define an outer envelope (96), and with at least one impeller blower (82) arranged downstream of the straw chopper (60) with impeller blades (84) that can rotate about an axis of rotation (88) that extends vertically, in which the impeller blades (84) are provided with outer edges (94) that conform to the envelope (96) of the chopper knives (76) and follow it very closely and are not in contact with it.
