Abstract
A threshing section for a combine harvester includes a rotor and a transition cone. The rotor has an axis of rotation, a downstream end, and an upstream end. The upstream end includes one or more blades for moving crop downstream in a direction of crop flow. The transition cone at least partially surrounds the upstream end of the rotor and the blades. An annular space is formed between a swept profile of the blades and an interior surface of the transition cone through which crop is introduced into the threshing section. A cross-sectional area of the annular space, which is measured in a radial direction, is substantially constant along at least a portion of a length of the swept profile.
