A chopping assembly for a harvesting implement having a blade assembly, a housing, and a guide. The blade assembly is disposed within the housing and the guide directs cornstalks toward an input port on the housing. The blade assembly not only cuts the cornstalk from its root but also chops the stalk into stover. A fluid dynamic force is created by the blade assembly to direct the stover with the aid of the housing to an output port.

A reel assembly of an agricultural header includes a first arm configured to support a reel of the reel assembly and a first pivot joint configured to pivotally couple the first arm to a frame of the agricultural header. The first pivot joint is configured to enable the first arm to pivot about a first local lateral axis of the agricultural header and about a longitudinal axis of the agricultural header relative to the frame. In addition, the reel assembly includes a second arm configured to support the reel and a second pivot joint configured to pivotally couple the second arm to the frame. The second pivot joint is configured to enable the second arm to pivot about a second local lateral axis of the agricultural header relative to the frame and to substantially block pivoting of the second arm about the longitudinal axis relative to the frame.

A header has frame sections that are joined for articulation with each other. The frame sections each form a partial working width of the header. The frame sections include outer lateral frame sections and a central frame section. A relief element is connected to the central frame section and an outer lateral frame section adjacent to the central frame section. The relief element is adjustable between a springy setting and a locked setting. The relief element has a spring movable in a loading direction and also a spatial body rigid in the loading direction. The spring is connected to the first outer lateral frame section by a bolt guided in a slotted hole of the rigid spatial body. A pivotable stop element with stops is pivotable into a plurality of pivot positions. A spring travel of the spring is adjustable by the stops of the stop element.

An agricultural vehicle including a chassis and a sectional header system carried by the chassis. The sectional header system includes a center section connected to the chassis and having a pair of lateral ends, at least one additional section, and at least one coupling assembly. The at least one coupling assembly includes at least one actuator and at least one connector. The at least one coupling assembly removably connects the center section to the at least one additional section. The at least one additional section is coupled to the center section in harvesting of a crop material and the at least one additional section is decoupled from the center section in transportation of the sectional header system.

An agricultural harvesting head for an agricultural harvester has a constant force assembly that changes the mechanical advantage of a spring applied to the mainframe of the agricultural harvesting head. As the mainframe of the agricultural harvesting head moves up and down on the front of the combine feederhouse, compressing and decompressing the spring, the constant force assembly changes the mechanical advantage of the spring such that the spring provides a relatively constant lifting force to the mainframe of the harvesting head as the mainframe moves up and down.

A header assembly for mounting upon a front end of a harvester combine's feeder house, the header assembly incorporating a central header which is adapted for fixed attachment to the feeder house front end; the header assembly further incorporating a lateral header and a pivot joint positioning an oppositely lateral end of the lateral header over the lateral end of the central header, the pivot joint being adapted for facilitating movements of the lateral header between a mowing position and a transport position, the lateral header cantilevering laterally over a crop edge upon pivoting to the mowing position and extending rearwardly upon counter-pivoting to the transport position.

An agricultural system includes a corn head with an end divider and an actuator that moves the end divider between a raised position and a retracted position. An actuator controller receives an input and automatically controls the actuator to move the end divider to a position based upon the input.

Systems, methods, and apparatuses for automatically controlling a position of a reel relative to wing of an agricultural header in response to movement of the wing are disclosed. In some instances, a position of the reel, such as a portion of the reel, is located at a different position relative to the wing based on an amount of articulation of the wing, such as an amount of angular displacement of the wing relative to a datum, such as a center frame of the header.

An agricultural harvester includes a chassis and a header carried by the chassis. The header includes: a center section supporting at least one center cutter and having a pair of lateral ends; a wing section linked to one of the lateral ends of the center section and supporting at least one wing cutter, the wing section being vertically moveable relative to the center section between a harvesting position and a transport position, the wing section being pivotable about a generally vertical pivot axis in the transport position and substantially prevented from pivoting about the pivot axis in the harvesting position; and an actuator linked to the wing section and configured to vertically move the wing section from the harvesting position to the transport position.

A corn head includes a first wing segment; a center segment; and a corn head adjustment system. The corn head adjustment system includes a first fold actuator and corn head hydraulics fluidly coupled to receive a fluid from a source and to selectively direct the fluid to the first fold actuator. During a fold process, the corn head hydraulics is configured to actuate the first fold actuator in order to lift and fold the first wing segment frame relative to the center frame. During an unfold process, the corn head hydraulics is configured to actuate the first fold actuator in order to lift and unfold the first wing segment frame relative to the center frame. The corn head hydraulics includes a force relief arrangement configured such that, at a predetermined position during the fold process and the unfold process, fluid pressure to the first fold actuator is reduced.
