Abstract
An agricultural harvester includes a threshing system having a rotor, a rotor cage surrounding the rotor and including a concave, and a transition cone defining an infeed to the rotor cage. The transition cone has a conical inner surface extending in an axial direction between an upstream end and a downstream end of the cone. A vane is mounted to the conical inner surface of the transition cone. The vane protrudes radially from the conical inner surface, and extends along an axial direction between the upstream end and the downstream end. The vane has a body extending along an axis and a cross-sectional shape that is not constant along the axis.
