Abstract
A combine harvester includes a rotor cage surrounding a rotor, a threshing space defined between the rotor cage and the rotor, and a transition section defining an infeed to the rotor cage. The transition section is mounted to the rotor cage at a location upstream of the rotor cage. The transition section has an inlet for receiving the crop material. The harvester also includes a crop conveying drum for conveying crop material to the inlet of the transition section and beneath the rotor. The crop conveying drum is at least partially encased by a shroud. The transition section includes a bottom wall, two side walls each having lower portions extending substantially vertical with respect to the bottom wall, and curved side walls each extending between the bottom wall and one of the side walls. The bottom wall is substantially tangential to a lower portion of the shroud.
