A dynamically operated concave threshing bar system, method, and apparatus wherein one or more threshing bars within a concave can dynamically move to various positions in real-time based on one or more conditions such as the type crop being harvested and on a determination by a combine harvester's computerized system, artificial intelligence (AI) system, or upon the operators' input, among others. The concave can include a concave frame having a pair of arcuate side members, a threshing bar, and an actuator coupled to the threshing bar, wherein the actuator can be configured to move the threshing bar along the arcuate side members of the concave frame.

A combine harvester for harvesting crop including a header, to cut crop, and a feeder house having an inlet, connected to the header, and an outlet, wherein the feeder house defines an interior and an exterior located outside the feeder house. The combine harvester includes one or more sensor assemblies connected to the feeder house, wherein each of the sensor assemblies provides a relative humidity value or both of a relative humidity value and a temperature value. A controller is operatively connected to the plurality of sensor assemblies, wherein the controller receives the relative humidity value or temperature value from each of the plurality of sensor assemblies. In response to the received relative humidity value or temperature value, the controller identifies a recommended setting for one or more harvester devices, parts, or components, to avoid grain loss and grain breakage resulting from crop moisture conditions.
