Disclosed is an articulated harvesting combine of a forward power processing unit (PPU) and a rear grain cart, wherein the PPU carries dual axially mounted engines with oppositely opposed crankshafts with one toward the rear grain cart and the other engine away from the rear grain cart, there being no comingling of flywheel output power flow between the two engines.

A combine harvester includes a feederhouse mounted to a chassis adapted at a front end to support a crop gathering header, a duct mounted on the feederhouse that is connected to a crop conveying passage of the feederhouse via a set of suction openings, a set of vent openings in the duct, each of the vent openings having a respective closure element movable between an open position and a closed position, and a fan arranged within the duct that can be operated in a first direction to create a suction airflow to extract dust from the crop conveying passage and discharge the dust through the duct, and in a second direction to create a blowing airflow to open the closure elements and vent air through the vent openings.

A cooler for a work vehicle includes at least one cooler core, a cooling fan associated with the at least one cooler core to produce a stream of air across the at least one cooler core, and a dust removal assembly including a filter associated with the at least one cooler core such that the stream of air passes through at least one collection surface of the filter. The dust removal assembly includes a suction channel placed such that it does not substantially interfere with the stream of air passing across the at least one cooler core, a blower fluidly coupled to the suction channel and configured to produce a suction region in and adjacent to the suction channel, and a filter carrier configured to carry at least a portion of the filter through the suction region such that particles captured by the filter are pulled into the suction channel.

A screening device and a self-propelled harvester with a screening device is disclosed. The screening device includes at least one suction nozzle that has an elongated hollow body with at least one suction opening which extends sectionally in the longitudinal direction and transverse direction of the hollow body, and is connected by at least one air duct in the interior of the hollow body to a connection arranged in the hollow body for connecting to a vacuum source. The suction opening is positioned facing a screen of the screening device. The air duct has a cross-sectional shape that increases in the vertical direction toward the connection starting from an outer end of the suction nozzle. An inner contour facing the suction opening of the air duct has a contour that substantially corresponds to an airfoil.

A combine harvester includes a threshing device 4 configured to perform a threshing process of threshing reaped grain culm in a threshing chamber 23, in which the threshing chamber 23 includes a threshing cylinder 31 configured to rotate around a front-rear axis X, and an arc-shaped receiving net 32 provided extending along an outer circumferential portion of the threshing cylinder 31, and a top plate 30 covering an upper portion of the threshing chamber 23 is supported detachably along the rotation axis direction of the threshing cylinder 31.

A crop ramp for use in a combine header is provided. The crop ramp includes a flat section, a curved section, and a flange. The flat section facilitates coupling the crop ramp to a cutterbar of the combine header. The curved section extends from the flat section. The curved section is configured to facilitate transfer of crop to a belt system of the combine header. The crop is transferred in a first direction defined from the flat section to the curved section. The flange extends from the curved section. The flange is configured to hover above the belt system of the combine header to prevent dirt from flowing in a second direction which is opposite to the first direction.

A fan assembly that has a fan hub having a plurality of blades extending radially therefrom and having a variable pitch and a controller in communication with the fan assembly to reposition a pitch of the plurality of blades. The controller establishes a variable maximum pitch of the plurality of blades based on an ambient temperature.

A combine crop trash removal system for mounting to a combine corn harvester using hydraulically driven air blowers coupled to the combine header control system for reduction and/or removal of stalks, leaves, dirt and dust type material from accumulating on the combine feeder house and obscuring the operators view of the operating combine header during operation of the combine harvester for corn picking. The air blower may also be driven electrically or pneumatically. The operator of the combine harvester controls the crop trash removal system from the operator cab of the combine harvester.
