A rotor assembly for harvesting a crop. The rotor assembly has a rotating portion defined along a rotation axis, a surrounding assembly at least partially surrounding the rotating portion, the surrounding assembly having at least one separation grate coupled to a support. The support defines an inner surface and has at least one interrupter receiver. The at least one interrupter receiver is selectively coupleable to an interrupter to position the interrupter radially inward of the inner surface towards the rotation axis.

A separator module for an agricultural machine. The separator module includes a feederhouse configured to receive crop from a harvesting platform, a casing enclosing a rotor positioned therein and rotatable relative to the casing for processing crop from the feederhouse, a cover extending between the feederhouse and the casing, and a noise control treatment coupled to the cover.

A grain cleaning system in a combine harvester including a frame, a chaffer sieve, and a lower sieve. A clean grain chute is located under the lower sieve to catch grain falling therefrom and is inclined to direct the caught grain to a clean grain trough. A tailings return chute is disposed under the clean grain chute and is configured to direct tailings to a tailings collection trough. A multi-configurable plate is mounted to the frame and positioned under a rear portion of the chaffer sieve. The plate is moveable between different operating positions. In a first operating position the plate is configured to guide material incident thereon to the tailings return chute. In a second operating position the plate is configured to guide material incident thereon to the clean grain chute.

A grain cleaning system in an agricultural harvester, that includes a chaff pan with a pivotal axis near an end of the chaff pan. The chaff pan has a dual locking system coupled thereto for holding the chaff pan in two different positions. The dual locking system has a first over-center locking arrangement and a second over-center locking arrangement. The first locking arrangement is used to hold the chaff pan in an upward position when the first locking arrangement is locked. The first locking arrangement includes a first linkage element; and a second linkage element. The second locking arrangement holds the chaff pan in a locked downward position when the second locking arrangement is locked. The second locking arrangement includes a first linkage element; and a second linkage element. The first linkage element of the first locking arrangement is also the first linkage element of the second locking arrangement.

An agricultural machine includes: a base member; a leading edge coupled with the base member and configured for receiving a flow of a material; and an assembly coupled with the base member, the assembly including a device and at least one flexible wiper coupled with the device, the device being configured for rotating and thereby for rotating the at least one flexible wiper therewith, said at least one flexible wiper thereby being configured for cleaning the material from the leading edge.

A procedure for collection and processing of weed seeds of the type which includes: a first step of collecting of a plant material; fourth step of threshing of the harvested material; a fifth step of separating of grains from material other than the grains; a sixth step of cleaning of the main material; a seventh step of transporting the main material to a discharge device; and an eighth step of storing the main material in an appropriate media. Also includes a second step of placing the material obtained by a thresher head assembly into at least one conveyor belt towards a trailer; a third step of transferring the plant material into a transport and hauling vehicle to a stationary processing plant; a ninth step of grinding the residues; a tenth step of introducing the MDG into densification device; and a tenth step of incorporating in a mixer the resulting grinding of the ninth step along with at least one supplement.

A harvester may include a chassis, a first separation frame movably supported by the chassis and upon which crop material is deposited, a second separation frame movably supported by the chassis and upon which the crop material is deposited; a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame and an adjustable link operably coupled between the separation frame and the chassis. The adjustable link facilitates adjustment of an orientation of the first separation frame independent of an orientation of the second separation frame without altering a reciprocation stroke distance.

A chopping assembly is configured to receive crop plants processed by an agricultural combine harvester. The chopping assembly includes an inlet and a plurality of blades rotatable about an axis. The plurality of blades is positioned downstream of the inlet. The chopping assembly also includes an outlet positioned downstream of the plurality of blades. The outlet is partially defined by a first wall and a second wall. The chopping assembly further includes an actuator coupled to the second wall. The actuator is configured to move the second wall relative to the first wall. A control processor is in communication with the actuator. The control processor is configured to receive a first signal corresponding to a condition representative of a characteristic of the crop plants. The control processor is also configured to generate a second signal operable to control the actuator based on the condition.

A system for an agricultural harvester includes a chopper assembly configured to separate a harvested material into debris and stalk. A primary extractor is configured to remove debris from the harvester. A sensor system is configured to capture data associated with harvested material conditions downstream of the primary extractor. A computing system includes one or more processors and one or more non-transitory computer-readable media that collectively store instructions that, when executed by the one or more processors, configure the computing system to perform operations. The operations include obtaining the data associated with the associated harvested material conditions downstream of the primary extractor, determining a current foliage ratio based on the data, determining an error between the current foliage ratio to a desired foliage ratio, and generating a harvest-related parameter of the primary extractor based at least in part on the error.
