An over-center latch for a concave combine comprises a mount directly attached to a concave combine or an accessory for a concave combine, a pentagonal base plate formed from steel, a lever with a loop at one end that is configured to attach to a catch plate, and a center pin that allows the lever to rotate with respect to a handle. Either the handle or the lever can be pulled into a vertical position.

A combine for harvesting a harvested material that includes a grain, the combine comprising: a threshing chamber comprising a series of threshing and separating apparatuses, sequentially arranged, comprising at least: (i) a straight bar concave (ii) a first round bar concave, and (iii) a second round bar concave. The size of each of the straight bar throats is smaller than a size of the first openings, and the size of each of the first openings is smaller than the size of each of the second openings.

An agricultural harvesting machine includes a chassis and a threshing system carried by the chassis. The threshing system includes a rotor, a frame assembly and at least one concave carried by the frame assembly. A latch mechanism supports and secures the concave relative to the frame assembly and includes a concave support bar, a clamping bar and a quick-connect, over center latch for tool-less operation.

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.

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.

An agricultural harvesting machine including a chassis, and a threshing section carried by the chassis. The threshing section includes a rotor, a plurality of frame assemblies adjustably positioned proximate to the rotor, a plurality of concaves and an adjustment mechanism. Each concave is carried by a corresponding frame assembly. The adjustment mechanism is coupled to the frame assemblies. The plurality of frame assemblies are X frame assemblies, with X being 2 or larger. The adjustment mechanism has at least one actuator, with there being Y actuators, with Y being 1 or larger. The adjustment mechanism is configured to adjust each of the X frame assemblies to different positions with Y actuators, where Y is less than X.
