A cleaning system for an agricultural harvester includes a first and second cleaning systems. A plurality of fans of a substantially similar diameter are fluidically coupled to the first and second cleaning systems. A controller generates and sends control signals to the fans to control the speeds of the fans.

A crop loss correction system receives one or more crop loss sensor signals that are indicative of crop lost by a harvesting machine. A correction component receives context information from a set of context sensing components to identify a context of the harvesting machine. The correction component corrects the crop loss sensor signals, based upon the context information, to obtain a corrected loss signal indicative of the sensed crop loss, corrected based on the mobile machine context. The corrected loss signal is output to an output device.

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.

A modular axle assembly for supporting wheels of an agricultural vehicle, such as a combine harvester. The modular axle assembly includes a first tube, a second tube parallel to the first tube, and at least one bracket connecting the first tube and the second tube.

A sensor assembly for attachment underneath a screen of a combine harvester is provided with a plurality of sensor units having sensor elements, a plurality of which sensor units are arranged one behind the other within a hollow profile which extends in the longitudinal direction of the screen.

A chaff pan assembly for an agricultural vehicle includes a chaff pan that is moveable between raised and lowered positions. A stationary bracket is mounted to a fixed point on the agricultural vehicle. A linkage interconnects the chaff pan to the stationary bracket and guides movement of the chaff pan between the raised and lowered positions. A locking member is moveably connected to the stationary bracket and is moveable between a locked position, in which the locking member is engaged with one arm of the linkage to prevent movement of the one arm of the linkage, and an unlocked position, in which the locking member is disengaged from the one arm of the linkage to permit movement of the one arm of the linkage.

A combine harvester includes a feederhouse configured to convey a crop material from a harvesting header, a threshing system configured to receive the crop material from the feederhouse and separate straw therefrom, and a cleaning system below the threshing system and configured to separate grain from chaff of the crop material. The cleaning system includes a reversible return system configured to receive the crop material from the threshing system, a grain pan below the return system, at least one oscillating grate configured to receive the crop material from the grain pan, and a blower configured to direct air rearward and upward through the oscillating grate. The return system delivers the crop material to a forward end of the grain pan in a first operating mode, and to a rearward end of the grain pan in a second operating mode. Related methods are also disclosed.

A cleaning system for a combine harvester has a chaffer and a blower configured to direct air rearward and upward through the chaffer. The chaffer has a perforated base, a plurality of longitudinal lateral walls, and a plurality of airbags, each of which is disposed adjacent to a lateral wall. An air supply is configured to inflate at least one of the airbags. Another cleaning system for a combine harvester also has a chaffer and a blower configured to direct air rearward and upward through the chaffer. The chaffer has a perforated base, a plurality of longitudinal lateral walls, a plurality of rigid members disposed adjacent to a corresponding lateral wall, and at least one actuator configured to move each rigid member relative to the corresponding lateral wall. Related methods are also disclosed.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The destructor is mounted on a suitable drive shaft within the straw path and the chaff and weed seed material is carried from the rear end of the sieve to the destructor on the straw chopper by one or more fans driving the material through a transfer duct.
