ABSTRACT:
A combine includes a housing enclosing a rotary separator. The rotary separator's discharge area is built such that the quality of the chopped crops is improved and a continuous discharge of crops is guaranteed. Guiding devices in the area of the axial-flow chopping device and on the inside of the housing's cover are designed such that the half of the guiding devices which are located in front of the chopping knives are essentially perpendicular to the pivotal axis of the rotary separator. In the area of the chopping knives, the housing is designed as a swiveling shutter so that the annular gap, located between the rotary separator and the housing, can be narrowed by the swiveling shutter.
