Abstract
Straw chopper assemblies are provided for a harvesting combine of the type having a rotor and cage threshing assembly. The straw chopper assemblies are located on each side of the rotor discharge for accepting material exiting the rotor. Each straw chopper assembly is formed from a curvilinear cage having and interior opening to accept the rotor discharged material, and an opening to distribute chopper straw outside of the harvesting combine. A rotating knife assembly is housed within each curvilinear cage. A stationary knife assembly is movable for the rotating knives to pass between adjacent pairs of stationary knives. Outlets are provided in material communication with the curvilinear cage openings for discharging chopped straw onto the ground adjacent to the harvesting combine. Hoods are located over each of the outlets to directing the discharged chopped straw onto the ground.
