A system for controlling the aggressiveness of a tailings processor that re-threshes tailings received from the grain cleaning system in an agricultural harvester is provided with at least one imaging device to image a grain sample. At least a portion of the grain sample has at least once passed through the tailings processor. A controller is connected to the imaging device and to an arrangement to automatically adjust the aggressiveness of the tailings processor. The controller is configured to automatically adjust the aggressiveness of the tailings processor using the arrangement, based on information provided by the at least one imaging device.

A lid is supported so as to be open and close by swinging upward and downward about a swing axis that is not parallel with the screw axis of a bottom screw.

A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.

A driver assistance system for a combine harvester that has a processing stage with an input for a crop flow, a first output for a useful flow and has abundant threshed grains, and a second output for a residual flow with scarce grains. At least one operating parameter of the processing stage is adjustable. The driver assistance system has an actuatable rethreshing device arranged at the second output of the processing stage, a residual grain sensor for detecting a proportion of threshed out grain in the residual flow downstream of the rethreshing device, and an evaluating device that turns the rethreshing device on and off, compares the proportions of threshed out grains in the residual flow when the rethreshing device is turned on and when the rethreshing device is turned off, and to adapt the at least one operating parameter of the processing stage based on the comparison.

This disclosure provides a lifting system for a grain combine. The grain combine includes a plurality of paddles connected transversely to a chain. Each paddle includes an inner edge attached to the chain and an outer edge. The chain is driven by two toothed pulleys. The system also includes a housing with a lower feed opening and an upper discharge opening. The lifting system includes at least one paddle having a cleaning element attached to its outer edge. The cleaning element is adapted to contact at least part of the inner surface of the lifting system housing in which part of the surface has perforations.

A combine harvester tailings return system includes a tailings conveyor and an ejection channel for depositing tailings upstream of a cleaning system. A proximity sensor is mounted to the ejection channel and is configured to sense the height of a layer of tailings during transit through the returns system.

A separating and cleaning mechanism for an agricultural combine may include: a return pan. The return pan includes a textured floor, two augers, and two motors coupled to the two augers, respectively, to selectively drive the motors in rotation independently. The textured floor may oscillate in a fore-and-aft direction to move grain toward the two augers.
