System and method for controlling threshing assembly operation of an agricultural harvester

Abstract

An agricultural harvester includes a threshing assembly configured to thresh crop material received from a feeder of the agricultural harvester. The threshing assembly, in turn, includes a concave and a rotor positioned relative to the concave such that a gap is defined between the concave and the rotor. Furthermore, the agricultural harvester includes an actuator configured to move the concave relative to the rotor to adjust a size of the gap. Additionally, the agricultural harvester includes a tailings assembly configured to receive incompletely threshed crop material that has passed through the concave. Moreover, the agricultural harvester includes an imaging device configured to capture image data depicting the incompletely threshed crop material present within the tailings assembly and a computing system communicatively coupled to the imaging device. As such, the computing system is configured to determine an amount of the incompletely threshed crop material present within the tailings assembly based on the captured image data. In addition, the computing system is configured to control an operation of the actuator based on the determined amount of the incompletely threshed crop material present within the tailings assembly.
