A straw chopper for a combine harvester having a chopper housing mounted to a combine for rotation about a transverse axis. The housing is movable from a chopping position, in which the chopper receives straw from the separator of the combine and chops and spreads the straw over a wide area, to a rearwardly raised windrowing position, in which straw falls from the combine to the ground in front of the chopper housing. By rotating the housing rearward and upward, increased access into the rear of the combine is possible. An electric motor driven lift actuator is provided to raise the chopper housing to the windrowing position where a mechanical latch locks the housing to the combine structure.

[ What is claimed is:] [1.]1. A chopper for a combine harvester having a structure and being adapted to move over a field to gather and process an agricultural crop having straw which, after processing, is discharged from a separator, the chopper comprising:a rotor rotatable about a transverse axis;a chopper housing supporting and surrounding the rotor, the housing defining an inlet and an outlet for the straw;the housing being mounted to the combine for rotation about a transverse pivot axis to move between a chopping position and a windrowing position, the inlet being positioned to receive discharged straw when the housing is in the chopping position, the housing rotating upward and rearward about the transverse pivot axis when moving to the windrowing position wherein the inlet is positioned to not receive discharged straw whereby the straw is allowed to fall from the combine to the ground without passing through the housing; andan inlet door mounted to the combine and inclined downward and rearward to the housing in the chopping position to direct straw into the inlet of the housing, the inlet door being pivotally mounted to the combine for selective rotation to a generally vertical position extending downward to facilitate access into the rear of the combine when the chopper is in the windrowing position.
