摘要： An agricultural header for use with an agricultural harvester is configured to cut crop when the agricultural harvester moves in a direction of travel. The agricultural header comprises a first frame, a side draper belt supported by the first frame and positioned to receive cut crop and advance cut crop laterally relative to the direction of travel, a second frame, a center draper belt supported by the second frame and positioned in register with the side draper belt to receive cut crop laterally therefrom and advance cut crop rearwardly toward the agricultural harvester opposite to the direction of travel, and a joint interconnecting the first frame and the second frame and enabling relative fore-aft and lateral translation between the first frame and the second frame.

摘要： A harvesting head for an agricultural harvester including a center frame section that is pivotally coupled to each of a left frame section and a right frame section. The elevation or height of the center frame section is determined by setting a height of the inner gauge wheels of the left and right frame sections. A gauge assembly for each of the left and right frame sections includes a linking member that spans between and operatively connects to outer and inner gauge wheels. The gauge assemblies are operably connected to the left and right frame sections to adjust an elevation of the outer and inner gauge wheels relative to the linking member to thereby adjust the elevation or height of the frame section when actuated by an actuation mechanism.

摘要： A float cylinder and accumulator are coupled between a header main frame and an attachment frame. The float cylinder is orientated so that its mechanical advantage in applying a float force to the header varies with the position of the main frame relative to the attachment frame. Similarly, the pressure exerted by the cylinder varies inversely with its mechanical advantage.

摘要： 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.

摘要： A control arm linkage system includes a pair of upper control arms and a pair of lower control arms to attach a crop harvesting header to a harvester frame of an agricultural harvester. The attachment of the header to the harvester via the control arm linkage system allows the header to move relative the harvester, with the header being displaced upward and heeled backwards in response to an upward force being imparted onto a lower surface of the header. The control arm linkage system thus allows the header to automatically adjust and adapt to unexpected raised mound that may be encountered along the path of the header during harvesting.

摘要： A harvesting system includes a header pivotably attached to a combine. The header includes a center section to which a left wing and right wing are pivotably attached. A wing locking system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially fiat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

摘要： An agricultural harvesting head has three frame sections. Each frame section is pivotally coupled to its adjacent frame section by two links. The two links are pivotally coupled to the two adjacent frame sections at both ends of each link.
