A combine harvester is disclosed with an infeed arrangement for receiving the harvested material, with a threshing device for degraining the harvested material, and with a cleaning device that is downstream from the threshing device for segregating the harvested material, and thereby separating the grain from the non-grain components. The cleaning device has a sieve device that can rotate about a rotational axis with an at least sectionally sieve-shaped sieve jacket that extends in a peripheral direction around the rotational axis. Separating the grain from the non-grain components is performed by the cleaning device by superimposing a rotary movement and oscillating movement of the sieve jacket such that the oscillating movement is directed transverse to the rotational axis of the sieve device, wherein the oscillating movement is caused by a segmentation of the sieve jacket in a peripheral direction, and a swinging of each peripheral segment of the sieve jacket about a pivot axis associated with the respective peripheral segment.

A harvesting vehicle including a cleaning section including a blower and at least one sieve. The sieve is configured to transport a layer comprising a mixture of grain kernels and residue material towards an exit edge of the sieve so that kernels fall through openings of the sieve and the residue remains on the sieve until it is ejected from the sieve by crossing the exit edge. The sieve may be subject to a grain loss, including a sieve-off loss and a blowout loss. The cleaning section further includes a sensor configured to determine whether the blowout loss or the sieve-off loss is a highest contributor to the grain loss. The cleaning section may also include a grain loss detector configured to measure the sieve-off loss and at least a portion of the blowout loss and a blowout sensor mounted above the sieve for measuring the blowout loss.

A harvesting machine includes a chassis; an engine to propel the harvesting machine; a header mounted on a front of the chassis; a cutter bar arranged on the header to cut crops during operation of the harvesting machine; a plurality of implements on the chassis configured to facilitate processing the crops cut by the cutter bar; at least one cutter bar load sensor arranged on the header and configured to collect cutter bar load data representing a load on the cutter bar resulting from cutting the crops; and a controller operatively coupled to the at least one cutter bar sensor. The controller is configured to receive the cutter bar load data, determine a cutter bar load value based on the cutter bar load data, and generate an adjustment command for an operational parameter associated with at least one of the implements based on the cutter bar load value.

A fan support arm with a base section configured to be coupled to a sidewall, a mount section configured to be coupled to a motor, and an arm section extending between the base section and the mount section. Wherein, the arm section has a profile that minimizes aerodynamic drag.

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 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 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.
