Combine harvesters may include crop processing systems having a grate subassemblies with flaps that, in some instances, are divided into groups that are independently movable and moveable in opposite directions between a fully open position and a fully closed position. Further, each of the grate assemblies may include an actuator that is operable to actuate simultaneously a portion of the flaps on each of the grate assemblies.

Combine harvester separation system

A residue distribution system includes a flow channel having a first lateral side and a second lateral side disposed. A spreader is positioned proximate a downstream end of the flow channel, and broadcasts the flow of the crop residue. A residue distributor is positioned within the flow channel and upstream of the spreader for directing the crop residue toward one of the first lateral side or the second lateral side of the flow channel to increase a mass of the crop residue that side of the spreader, whereby a discharge density of the crop residue on that side of the spreader is increased to overcome effects of a crosswind or an uphill side-slope on broadcast distribution of the crop residue.

Spreader distribution compensation through material flow manipulation

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.

Cross vented residue disposal system for an enclosed combine body

A residue management system comprises a chopper to chop crop residue, a residue spreader, and a floor extension. The residue spreader is mounted for pivotable movement relative to the chopper between a dispersal position to disperse crop residue and a windrow position to deposit crop residue in a windrow. The residue spreader comprises a first spreading device, a second spreading device, and a splitter positioned laterally between the first and second spreading devices to divide flow of crop residue therebetween. A floor of the chopper and a floor of the residue spreader are spaced apart from one another to define a gap. The floor extension projects rearwardly from the floor of the chopper partially over the floor of the residue spreader about the gap alongside the splitter to guide flow of crop residue from the chopper to the residue spreader.

A windrow system of a combine includes a chopper and a spreader. The chopper includes a chopper housing having a roof and a rotor assembly positioned in the chopper housing, and the spreader is pivotably coupled to the chopper and includes a top surface and an impellor that is positioned below the top surface and includes one or more blades for rotatably conveying crop residue rearwardly and outwardly from the spreader. The windrow system also includes top segment coupled to a main body of the combine, a first curtain, and a second curtain having a portion thereof positioned outwardly of the first curtain. Each of the curtains are movable relative to the main body of the combine when the spreader and/or chopper move between at least one of wide and narrow positions, chopping and windrowing positions, and chopping and stowed positions.

Windrow system with split curtains and method thereof

A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.

System to reduce material accumulation on top of a power residue spreader on an agricultural combine

A combine double-decker crop residue spreader for use with a rotating chopper having chopper blades and through which air is blown may include a divider panel separating a lower portion from an upper portion of the spreader. The divider panel extends rearwardly from a location where the chopper blades transition from rotating towards the divider panel to rotating away from the divider. An airflow conduit extends above the divider panel in the upper portion to rearwardly direct air flow. At least one lower vertical panel below the divider panel in the lower portion rearwardly directs crop residue.

A residue deflector is disposed in a combine body, and positioned along an airflow path to guide residue from an exit end of a cleaning shoe and a threshing and separation assembly, to a residue chopper. The deflector is configured with a plurality of spaced fingers so that air can pass through the deflector between the fingers.

An arrangement for switching over a combine harvester between swath deposit operation and wide distribution operation comprises a front element and a rear element which follows downstream. The rear element may be attached in an articulated fashion, in an inherently rigid fashion, at its upstream end about a first pivoting axis and may be moved between a swath deposit position and a wide distribution position by an adjustment drive. The front element may be attached in an articulated fashion at its upstream end about a second pivoting axis, may be inherently rigid and may also be coupled to the adjustment drive.

A conveyor drum () for an endless belt conveyor () for a feederhouse of an agricultural combine () includes an elongate drum (), cogs () fixed to the drum for driving endless belts (), and retainers () fixed to the drum () to maintain the endless belts () in a proper operating position.

A wear strip arrangement for an endless belt conveyor for a feederhouse of an agricultural combine includes a first body that is configured to be attached to a slat that in turn is attached to the endless belt.

A combine harvester has a straw chute with a straw conveyor which comprises a conveyor rotor which can be set into rotation and has dogs distributed helically around the conveyor rotor.

Combine harvester with a straw chute and a straw conveyor

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.
