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.

An operator interface for a combine harvester, having a display device, input means and a processor configured to activate the display device such that the display device depicts having an elongated element, a scale being assigned thereto, and a first marking, the position thereof relative to the elongated element depending on an operating parameter of the threshing device and/or the cleaning device. A second marking and/or third marking, which represents a lower and/or upper limit of the setting range of the operating parameter which is predetermined depending on the type of crop, is assigned to the elongated element in the diagram.

The present invention comprises a removable cover plate assembly, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The cover plate assembly improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. Moreover, the cover plate assembly of the present invention enables a single set of concave grate assemblies to better harvest a wider variety of crop types.

A concave section for a harvester includes a concave body having an upstream side, a downstream side, a leading end and a trailing end. The concave body defines an arcuate crop engagement face facing radially inwardly. A plurality of crop passage openings are defined through the arcuate crop engagement face. A cover is configured to at least partially cover at least some of the crop passage openings. The cover is carried by the concave body and is movable thereon between at least two different positions to adjust a degree of openness of at least some of the crop passage openings.

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.

A combine harvester including a frame and two axial-flow crop processing rotors mounted to the frame. An inner support structure is located between the two rotors and is mounted to the frame by a first linkage. Two outer support structures are located outboard of the two rotors and are mounted to the frame by respective second and third linkages. The inner support structure and two outer support structures carry first and second pluralities of concave grate segments at a radial distance from the respective rotors. A concave adjustment system includes a first actuator coupled to the first linkage which is configured to raise and lower the inner support structure. A second actuator is coupled to one of the second and third linkages and is configured to raise and lower at least one of the two outer support structures.
