A threshing concave assembly is disclosed having a threshing concave bar wherein the threshing bar is comprised of two threshing surfaces having a dihedral angle relationship relative to each other. In addition, in another aspect the threshing bar can be comprised of two dihedral surfaces whereby one surface face has about 130% greater surface area than its adjacent surface face. Alternatively, one surface face of the threshing bar can be 1.3x wider than its adjacent surface face. In another aspect the threshing bar can be comprised of two dihedral surfaces whereby one surface face has about a 170% greater surface area than its adjacent surface face.

A monitoring system for a combine harvester. The monitoring system includes a sensor configured to provide a measurement wave to a flow of crop residue on the harvester and to receive a response wave from the flow of crop residue. The monitoring system further includes a processor having an input terminal for receiving a response signal of the sensor representative of the response wave. The processor is configured to determine a crop parameter associated with the density of the flow of crop based on the response signal of the sensor. The processor further has an output terminal for outputting a density signal representing the crop parameter.

A combine harvester includes a threshing device 4 configured to perform a threshing process of threshing reaped grain culm in a threshing chamber 23, in which the threshing chamber 23 includes a threshing cylinder 31 configured to rotate around a front-rear axis X, and an arc-shaped receiving net 32 provided extending along an outer circumferential portion of the threshing cylinder 31, and a top plate 30 covering an upper portion of the threshing chamber 23 is supported detachably along the rotation axis direction of the threshing cylinder 31.

A self-propelling combine and a method for operating a self-propelling combine are disclosed. The combine includes an axial spreader, which generates a residual flow of material and supplies the residual flow of material to a downstream distribution device that discharges the residual flow of material from the combine. The axial separator in the end-side material delivery region has at least one guide element that may be moved by an actuator, thereby affecting a distribution of the exiting residual flow of material over the supply width of the distribution device. The distribution of the residual flow of material is detected by at least one sensor unit, and when a deviation from a target distribution is detected, the guide element is adjusted. A control device receives and uses a signal representing a side wind used to automatically adjust of the at least one guide element.

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.
