A feederhouse assembly for an agricultural harvester includes a feederhouse comprising an inlet end, a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, and a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse. The frame defines a crop opening therethrough and is configured to carry a harvesting header. An agricultural harvester includes a chassis, the feederhouse assembly mounted to the chassis, and a processing system carried by the chassis and structured to receive crop material from the feederhouse.

An attachment system for an agricultural vehicle including a feeder housing and a header. The attachment system includes at least one feeder connecting member configured for being located on and movably connected to the feeder housing, and at least one header connecting member configured for being located on the header. The at least one feeder connecting member is automatically connectable and securable to the at least one header connecting member as the feeder housing lifts the header.

A harvesting head for a combine and method of operating. An attachment frame at an aft end of the head attaches with a combine feederhouse. A main frame of the head is movably connected to the attachment frame, and the main frame has a range of travel with respect to the attachment frame. A resilient float element is provided between the attachment and main frames. A flexible cutterbar on the main frame operates to cut crops. The cutterbar is supported on the main frame by a plurality of pivoting arms distributed across a width of the head. With the main frame in a nominal intermediate position within the range of travel, the plurality of pivoting arms have 10 percent or less of total available travel as upward travel and at least 90 percent of total available travel as downward travel when the head is set in the nominal position.

A faceplate sub-assembly for an agricultural vehicle includes a faceplate and at least one biasing element. The faceplate is configured to be connected between (i) a feederhouse defining an inlet opening through which crop material is delivered for processing by the agricultural vehicle, and (ii) a header of the agricultural vehicle. The faceplate is configured to be pivotably mounted to the feederhouse such that the faceplate is configured for lateral tilting relative to the feederhouse. The at least one biasing element has one end connected to the faceplate and another end that is configured to be connected to the feederhouse for reducing a friction force at the interface between the faceplate and the feederhouse to accommodate lateral tilting of the faceplate.

A system for a header assembly that has a center frame configured to pivot relative to an adapter frame about at least one center axis, a center actuator coupled to the center frame to selectively provide a biasing force thereto, a first arm assembly configured to pivot relative to the center frame about at least a first arm axis, a first actuator coupled to the first arm assembly to selectively provide a biasing force thereto, a controller in communication with the center actuator and the first actuator to selectively alter performance characteristics of the center actuator and the first actuator, and a user interface in communication with the controller and having at least a first option and a second option. Wherein, the controller adjusts the performance characteristics of both the center actuator and the first actuator when the user interface is transitioned between the first option and the second option.

A harvesting machine includes a main frame, a cutter assembly, and a conveyor system. The cutter assembly is pivotally coupled to the main frame. The cutter assembly includes a cutter bar configured to sever crop material adjacent to the ground and a cutter frame configured to support the cutter bar for pivotal movement relative to the main frame. The conveyor system is coupled to the main frame and configured to convey severed crop material in a rearward direction away from the cutter bar toward a central feed drum of the harvesting machine.

Feederhouse gearboxes are provided for installation on combine harvesters. In embodiments, the feederhouse gearbox includes a gearbox housing, an output shaft rotatable about an output axis, and a primary drive input. The primary drive input is mechanically linked to an engine of the combine harvester when the feederhouse gearbox is installed thereon. A reverser drive input is mechanically linked to a reverser motor of the combine harvester when the feederhouse gearbox is installed on the combine harvester. The feederhouse gearbox further includes a selector mechanism within the gearbox housing and movable between a primary drive position and a reverser drive position, a primary gear train transmitting rotation from the primary drive input to the output shaft when the selector mechanism is in the primary drive position, and a reverser worm drive transmitting rotation from the reverser drive input to the output shaft when the selector mechanism is in the reverser drive position.

A header for an agricultural vehicle includes a frame; a plurality of supports, each of the plurality of supports extending from a respective proximal end at the frame to a respective distal end located forward of the frame; a channel that is either formed on or mounted to at least one of the supports; and a belt positioned over and on the plurality of supports. The belt defining a projection that is positioned within the channel in order to constrain the belt in a fore to aft direction of the header.
