Zusammenfassung:An agricultural harvester (10) includes a threshing system having a rotor (40) , a rotor cage (42) surrounding the rotor (40) and including a concave, and a transition cone (80) defining an infeed to the rotor cage (42). The transition cone (80) has a conical inner surface (82) extending in an axial direction between an upstream end (84) and a downstream end (86) of the cone (80). A vane (88a) is mounted to the conical inner surface (82) of the transition cone (80). The vane (88a) protrudes radially from the conical inner surface (82), and extends along an axial direction between the upstream end (84) and the downstream end (86). The vane (88a) has a body extending along an axis (8) and a cross-sectional shape that is not constant along the axis (B).
