The rotor of a residue-chopping unit for combines cuts wider paths by virtue of the provision of laterally corrugated blades for increasing the amount of surface area in the knife-like edges which contact the residue during rotation of the rotor, all without appreciably increasing the masses of the blades. Each blade is shaped to concentrate the mass thereof at its outermost free end outside its center of gravity. A vane on certain of the blades creates an increased airflow through the chopping unit.
