Combine threshing system with crop flow control

A threshing system for an agricultural harvester, the threshing system comprising:

• a rotor comprising an elongated body, the elongated body having:
• a first end adapted to receive material from a feeding mechanism;
• and
• a second end opposite the first end;
• a substantially cylindrical cage that surrounds at least a portion of the rotor, the cage comprising an inner surface spaced radially apart from the rotor to define a threshing space between the rotor and the cage;
• a housing attached to the cage and extending longitudinally along at least a portion of the cage;
• and
• a material flow adjustor for controlling axial movement of material through the cage, the material flow adjustor being movably mounted adjacent to the threshing space and in an interior space of the housing, the material flow adjustor being advanceable from the interior space into the threshing space through an opening in the cage, the material flow adjustor comprising at least one material conveying edge adapted to enter the threshing space,
• wherein the rotor is configured to rotate relative to the cage about a first axis of rotation to axially convey material from the first end of the rotor toward the second end of the rotor,
• wherein the material flow adjustor is moveable between a first operative position, in which the at least one material conveying edge is spaced from the rotor in a radial direction by a first distance, and a second operative position, in which the at least one material conveying edge is spaced from the rotor in the radial direction by a second distance, the second distance being less than the first distance,
• wherein, when the material flow adjustor is in the first operative position, the material flow adjustor is contained entirely within the interior space of the housing and outside of the threshing space, and
• wherein, when the material flow adjustor is in the second operative position, at least a portion of the material flow adjustor extends into the threshing space.

• and
• a material flow adjustor for controlling axial movement of material through the cage, the material flow adjustor being movably mounted adjacent to the threshing space and comprising at least one material conveying edge adapted to enter the threshing space,
