A residue management system for an agricultural vehicle includes: a straw hood defining a first rear opening and a second rear opening; a windrow chute held adjacent to the first rear opening; a spreader assembly held adjacent to the second rear opening; a conveyor held within the straw hood and defining a conveyor axis of rotation; and a selection door pivotably coupled to the straw hood and defining a pivot axis which is rearward and below the conveyor axis of rotation, the selection door being configured to switch between a first position in which material from the conveyor is directed toward the first rear opening and a second position in which material from the conveyor is directed toward the second rear opening.

A display controller controls a display device in a harvester to display an interface showing adjustments to combine harvester settings, received from a remote computing system, along with an adjustment actuator. A settings adjustment is made based on user actuation of the adjustment actuator input is received through the settings adjustment actuator on the displayed interface. A verification notification is sent to the remote computing system, showing the adjusted settings on the combine.

Combine harvesters are provided for use in harvesting seed corn from corn plants in fields. In connection therewith, a method for producing such seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by one of the combine harvesters, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.

Embodiments of a kernel-level grain monitoring system include a grain camera positioned to capture bulk grain sample images of a currently-harvested grain taken into and processed by a combine harvester, a moisture sensor, and a display device. A controller architecture is coupled to the grain camera, to the moisture sensor, and to the display device. The controller architecture is configured to: (i) analyze the bulk grain sample images, as received from the grain camera, to determine an average per kernel (APK) volume representing an estimated volume of a single average kernel of the currently-harvested grain; (ii) repeatedly calculate one or more topline harvesting parameters based, at least in part, on the determined APK volume and the moisture sensor data; and (iii) selectively present the topline harvesting parameters on the display device for viewing by an operator of the combine harvester.

A combine harvester includes a housing having a rear hood and defining an interior, a blower for generating an air stream in a substantially rearward direction, and a cleaning system separating residue from a crop material such that the residue is transported via the air stream rearwardly to be discharged from the housing. A chopper rotor assembly is disposed within the interior below the rear hood and includes a chopper rotor having a plurality of blades for chopping the residue as it is received via the air stream. A chopper housing is disposed within the interior and defines an inlet of the chopper rotor for receiving the residue and an outlet spaced rearward from the chopper rotor for discharge of the chopped residue from the interior of the housing. An air gap through which the air stream may exit the interior is defined between the rear hood and chopper rotor.

A combine harvester includes a housing having a rear hood and defining an interior, a blower for generating an air stream in a substantially rearward direction, and a cleaning system separating residue from a crop material such that the residue is transported via the air stream rearwardly to be discharged from the housing. A chopper rotor assembly is disposed within the interior below the rear hood and includes a chopper rotor having a plurality of blades for chopping the residue as it is received via the air stream. A chopper housing is disposed within the interior and includes a roof structure located above the chopper rotor such that a minimal gap is defined therebetween. The air stream flows out of the interior via a flow path defined through the chopper rotor without being substantially redirected from flowing in the rearward direction by the plurality of blades of the chopper rotor.

An agricultural grain cleaner includes an inlet chute having an inlet end and an outlet end positioned below the inlet end. A crop distribution member is positioned adjacent the outlet end of the inlet chute. The crop distribution member includes a distribution disc rotatable relative to the inlet chute about a vertical central axis to impart a horizontal trajectory, away from the central axis, to crop material supplied to the distribution disc from the inlet chute. A fan is operable to generate an air stream from below the crop distribution member, across the horizontal trajectory, to an air-chaff outlet. A grain collection chute has an inlet to receive grain that is cleaned of chaff by the air stream. A tailings collection chute is positioned adjacent to the grain collection chute on a radially inner side thereof.

A combine harvester self-adaptive cleaning control apparatus, includes a return plate, a cleaning sieve, a cleaning centrifugal blower, an impurity collection and stirring auger, a grain collection and stirring auger, a cleaning grain loss monitoring sensor, a grain tank grain impurity rate automatic monitoring apparatus, and an on-line monitoring and control system. The on-line monitoring and control system is connected to the cleaning centrifugal blower, the cleaning grain loss monitoring sensor, the grain tank grain impurity rate automatic monitoring apparatus, and a power driving mechanism of a louver sieve having an adjustable opening. Also disclosed is a self-adaptive cleaning method of the cleaning apparatus which can automatically adjust various working parameters according to a working quality of a working process, control failure rate, and improve a down-time working time for the apparatus.

An agricultural harvester includes a grain processing section having a sieve. The sieve is driven in fore and aft oscillation while permitting side to side movement by a pair of cast members interconnected each having three mounting points. Two of the mounting points of the members are interconnected by flexible rubber bushings and the third mounting point of one of the members receives fore and aft oscillating movement and the third mounting point on the second of the members pivotally interconnects to the sieve to drive it into fore and aft oscillation while permitting side to side movement.

An agricultural harvester includes a straw walker arrangement positioned downstream from a threshing and separating system. The straw walker arrangement includes a first straw walker positioned to receive crop material from the threshing and separating system, a second straw walker positioned downstream from the first straw walker, and a rotatable drum positioned between the first straw walker and the second straw walker. The rotatable drum is operable to convey crop material from the first straw walker to the second straw walker.
