A self-propelled combine harvester and a method for operating a self-propelled combine harvester. The self-propelled combine harvester comprises a feed channel which is pivotably articulated to a combine harvester about a horizontal axis for height adjustment by linear actuators, and a draper arranged or positioned on the feed channel, which comprises a center segment with a central frame segment and two side segments each with an outer frame segment. The particular side segment is pivotably connected to the center segment by a frame joint comprising a pivot axis, and the particular side segment is positionable relative to the center segment by an actuatable actuator. The combine harvester includes a control unit that is configured to actuate the actuators in order to align the side segments relative to the center segment depending on the height adjustment of the feed channel when lifting the draper.

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.

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.

Apparatuses, systems, and method for moving a wing frame of an agricultural head from a folded position to an unfolded position and to articulate the wing frame when in the unfolded configuration using a single actuator are disclosed. In some implementations, an agricultural head may include a center frame; a wing frame coupled to the center frame; and an intermediate portion disposed between the center frame and the wing frame. The intermediate portion may be pivotably connected to the center frame at a first pivot axis and pivotably connected to the wing frame at a second pivot axis. The first pivot axis may be offset from the second pivot axis.

In some implementations, an agricultural head may include a center frame; a wing frame coupled to the center frame; a first pivot axis pivotably connecting the wing frame to the center frame, the first pivot axis being configured to facilitate rotation of the wing frame between a folded configuration and an unfolded configuration relative to the center frame; and a second pivot axis, offset from the first pivot axis, pivotably connecting the wing frame and the center frame. The second pivot axis may be configured to facilitate articulation of wing frame, in the unfolded position, relative to the center frame.

An agricultural harvester includes a header with an infeed assembly including a driving element configured to rotate; a cylinder rotationally coupled to the driving element and having a plurality of openings formed therein; and a paddle assembly eccentrically positioned and rotationally held within the cylinder. Each paddle assembly includes a plurality of paddles variably positioned through the openings in the cylinder. Each paddle includes a laterally slidable wing that withdraws into the cylinder when the paddle retracts into the cylinder, and slides outwardly as the paddle extends form the cylinder.

The aim of the invention is to increase the feed rate of the cutting unit while achieving lower costs. This aim is achieved, according to the invention, in that at least two reel support arms (26) supporting a reel part (24a, 24b, 24c) are interconnected, for conjoint rotation, by means of a torsion shaft (30a, 30b), the reel support arms (26a, 26b, 26c, 26d) and the torsion shaft (30a, 30b) form a reel support unit (32), the reel support unit (32) is connected to an adjustment drive (28a, 28b), which acts on one or more reel support arms (26a, 26b, 26c, 26d) and/or on the torsion shaft (30a, 30b) and, in the event of adjustment movements of the remotely controlled adjustment drive (28a, 28b), raises or lowers the associated reel part (24a, 24b, 24c), the torsion shaft (30a, 30b) has, on a first side, a bearing point (34) fixed in the axial direction of the torsion shaft (30a, 30b), and the torsion shaft is mounted, on a second side, in a plain bearing (38).

Provided in an implement for a harvesting machine. The implement may include a plurality of crop engaging members that may extend from one or more crop engaging member supports. The crop engaging member support(s) may extend from an extension member. At least a portion of the crop engaging member support(s) may be movable with respect to the extension member between harvest and nonharvest positions. In some implementations, the implement may include at least two extension members. Each extension member may be joined to one or more crop engaging member supports, from which crop engaging members may extend. One or more of the extension members may be movable between harvest and nonharvest positions.

A row crop header for harvesting crop in a field comprises a header frame having a center section and a pair of side wing sections operatively coupled to the center section. An upper link is pivotally coupled between the center section and each one of the side wing sections adjacent the top portion thereof. A lower link is pivotally coupled between the center section and each one of the side wing sections adjacent the bottom portion thereof. The upper links and lower links provide independent pivotal movement of the side wing sections relative to the center section to contour to the surface of the field of crops to be harvested. An automatic float system is operatively coupled between the center section and each one of the side wing sections to adjust the weight of the side wing sections on the surface of the field and allow the side wing sections to float relative to the center section.
