An adjustable vane system for use with a rotor cage of a threshing system of an agricultural harvester, the vane system comprising:
- a vane comprising:
- a generally helically curved inner profile;
- a surface being an outer profile that is opposite the inner profile and is generally helically curved over a portion of the vane, the outer profile being configured to be positioned closer to the rotor cage than the inner profile;
- and
- a flat portion located midway along the outer profile, wherein a distance between the flat portion and the rotor cage is greater than a distance between a curved portion of the outer profile and the rotor cage.
A threshing system for use in an agricultural harvester, the threshing system comprising:
- a rotor cage comprising a plurality of slots therein, the rotor cage comprising a generally cylindrical inner surface;
- and
- a plurality of adjustable vanes pivotally coupled to the rotor cage, each vane comprising:
- a generally helically curved inner profile;
- a surface being an outer profile that is opposite the inner profile and is generally helically curved over a portion of the vane, the outer profile being positioned closer to the rotor cage than the inner profile;
- and
- a flat portion located midway along the outer profile, wherein a distance between the flat portion and the rotor cage is greater than a distance between a curved portion of the outer profile and the rotor cage.
