<p>A crop harvester (20) is operable to process severed crop material and includes a harvester frame (22), crop-processing rotor (28), concave (32), and cam element (82). The concave (32) is shiftably supported relative to the harvester frame to be moved generally toward or away from the rotor along a direction transverse to the rotor axis (R) to control processing of severed crop material. The cam element is shiftably mounted relative to the harvester frame and is operably coupled to the concave so that shifting of the cam element relative to the harvester frame causes shifting of the concave relative to the rotor along the transverse direction.</p> |
