An agricultural harvester includes a chassis; a threshing and separating system carried by the chassis and including at least one threshing rotor mounted in a longitudinal direction of the agricultural harvester; a grain pan carried by the chassis that receives crop material from the threshing and separating system, the grain pan being configured to shake in a fore-to-aft direction and a lateral direction; and a cleaning system carried by the chassis supplied with crop material from the grain pan, the cleaning system including at least one sieve configured to shake in the lateral direction out of phase with the grain pan.

A grain quality sensor comprising a photosite array, an illumination source, a filter, and an electronics module, wherein the illumination source directs light onto a crop sample, wherein the filter limits passage of light into different parts of the photosite array such that certain locations on the photosite array only receive certain wavelengths of light reflected or fluoresced by the crop sample, wherein an electronics module is electrically connected to the photosite array and capable of determining which parts of the photosite array received light and the wavelengths of the light received, wherein the electronics module can analyze the optical data received by the photosite array, and wherein the analysis of the optical data is used to determine the composition of the crop sample.

A system for cleaning sensor assemblies of an agricultural harvester includes an elevator assembly configured to convey harvested crop material, with the elevator including an elevator frame. Furthermore, the system includes a sensor assembly positioned within the elevator assembly, with the sensor assembly including a weigh plate coupled to the elevator frame such that the weigh plate and the elevator frame define a gap therebetween. The sensor assembly further includes a load sensor coupled between the elevator frame and the weigh plate such that the load sensor is configured to generate data indicative of a weight of the harvested crop material present on the weigh plate. Additionally, the system includes a cleaning device configured to remove debris from the gap.

A system for an agricultural harvester can include a support structure configured to be operably coupled with an elevator housing. A carrier can be operably coupled with the support structure. A vision-based sensor can be operably coupled with the carrier. One or more light sources can be operably coupled with the carrier. A panel can be positioned along a portion of the carrier. A cleaning system can be configured to remove debris from the panel positioned between at least one of the vision-based sensor and the one or more light sources. A computing system performs various operations. The operations can include determining a detected percentage of pixels within the data indicating debris on the panel on the panel and initiating a cleaning routine to remove at least a portion of the debris from the panel.

An agricultural harvester has a chassis carrying a header removably attached to a feeder housing for gathering a type of crop and feeding it into the agricultural harvester. The feeder housing is connected to a threshing and separating system for separating grain from MOG, which leads to a grain cleaning system for cleaning the separated grain. The grain cleaning system has at least one sieve operable to oscillate fore and aft, and at least one cleaning fan. The grain cleaning system also has a side shaker mechanism operable to produce a side to side shaking motion. A control system is connected to the side shaker mechanism and is operable to automatically adjust the amount of side to side shaking motion on the basis of the type of crop and on the basis of the amount of side slope upon which the agricultural harvester is situated.

A combine harvester includes one or more threshing rotors (5) mounted in the harvester, a grain pan (7) and a set of sieves (8), and a drive mechanism configured to drive a longitudinal reciprocating motion of the grain pan (7) and superimpose a lateral reciprocating motion component on the longitudinal reciprocating motion.

A sieve system of an agricultural vehicle for separating crop residue from grain, the sieve system including a frame, a plurality of sieve sections, a plurality of dividers and a pivoting system. The sieve sections are pivotally coupled to the frame. The sieve sections include a first sieve section. The dividers include a first divider coupled to the first sieve section. The pivoting system is coupled to the first sieve section and the first divider, to thereby pivot the sieve section at a first angle about a first axis. The pivoting system also either pivots the divider at a second angle about a second axis or flexes the divider at the second angle. The first angle is relative to the frame, and the second angle is relative to the sieve section.

A combine harvester including at least one straw walker extending in a longitudinal direction of the harvester and supported by a front and rear shaft. The shafts are rotatable about respective rotation axes, and each shaft provided with one or more eccentric portions. The straw walker is rotatably mounted on an eccentric portion of the respective front and rear shafts, so that the simultaneous rotation of the shafts actuates a reciprocating motion of the straw walker. The combine further comprises a pivot frame and one or more actuators, configured to adjust the angular position of the frame by pivoting the frame about a pivot axis oriented transversally to the longitudinal direction. The front and rear shafts are configured to rotate with respect to the pivot frame, so that the straw walker's angular position is adjustable while the straw walker executes the reciprocating motion.

A topographical indication for a field is detected by an aerial sensor and, based on the topographical indication, an area of consistent elevation is calculated. An estimated yield indication for a field is also detected, and an area of consistent estimated yield is calculated. With a controller, a calibration candidate zone is generated, wherein the calibration candidate zone comprises an area of the field with a consistent topography and a consistent estimated yield along a width and a length of the area.

A cleaning assembly for a harvester operable to clean a crop while moving along a direction of the crop flow and comprising multiple cleaning sub-assemblies has a control system coupled to each of the cleaning sub-assemblies and operable to control the operation of each of the cleaning sub-assemblies in function of separate cleaning sub-assembly control settings for each of the cleaning sub-assemblies.
