A system for controlling an operative parameter of a harvesting platform of an agricultural harvesting machine comprises a sensor adapted to provide downed crop information indicative of a characteristic of downed crop in a field to be harvested and an electronic control unit adapted to control an operative parameter of at least one of a reel and a cutter bar table position of the harvesting platform based upon the downed crop information.

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 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.

A frame assembly for an agricultural header includes an intermediate frame and arms coupled to the intermediate frame. Each arm is configured to couple to a frame of the agricultural header at a respective joint and rotate relative to the frame of the agricultural header at the respective joint. Each respective joint is disposed on an axis extending through pivot joints of the agricultural header. The pivot joints pivotally couple header arms to the frame of the agricultural header, and the header arms are configured to support a cutter bar of the agricultural header. The frame assembly also includes springs coupled to the intermediate frame. Each spring is coupled to a respective arm of the arms, and the springs are configured to flex to enable movement of the frame of the agricultural header relative to the intermediate frame.

A frame assembly for an agricultural implement includes a frame having laterally opposite first and second sides, a first arm disposed at the first side and configured to rotate relative to the frame, a first biasing member coupled to the first side and to the first arm, a second arm disposed at the second side and configured to rotate relative to the frame, and a second biasing member coupled to the second side and the second arm. The first and second arms are configured to couple to the agricultural implement and to enable the agricultural implement to rotate about a longitudinal axis via rotation of the first arm and rotation of the second arm. The first and second biasing members are configured to flex in response to the rotation of the first and second arms, respectively.

An infeed deck for an agricultural header includes an infeed belt configured to convey agricultural crops toward an auger of the agricultural header and a roller configured to drive rotation of the infeed belt or configured to be driven via rotation of the infeed belt. The roller is configured to couple to an intermediate frame assembly coupled to the agricultural header and is configured to pivot about an axis extending parallel to a lateral axis and to pivot relative to an intermediate frame of the intermediate frame assembly. The intermediate frame assembly is configured to enable a header frame of the agricultural header to rotate about a longitudinal axis and relative to the intermediate frame.

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

A method for controlling header cut height on a combine. The combine includes an adapter, a header pivotably mounted to the adapter, a cutter bar assembly operatively extending across a front portion of the header, and a gauge wheel pivotably coupled to the header. The method comprising the steps of receiving a request to adjust a height of the cutter bar assembly, determining whether a position of a first cylinder is greater than a value, and if it is determined that the position of the first cylinder is greater than the value, using the first cylinder to adjust the height of the cutter bar assembly.

A header for an agricultural vehicle includes: a header frame; a flexible cutter supported by the header frame and including a plurality of cutting edges; a support arm coupled to the flexible cutter and pivotable with respect to the header frame; and a sensor assembly including a pivot sensor directly coupled to the support arm and a linkage including a linkage arm coupled to the pivot sensor and the support arm such that pivoting of the support arm also causes pivoting of the linkage arm, the pivot sensor being configured to output a total pivot angle signal corresponding to a pivot angle of the support arm plus an additional pivot angle of the linkage arm when the support arm and the linkage arm pivot.

The present invention relates to a method for operating a cutting unit (1) that has a cutter bar (6) that is operated rigidly or flexibly, depending on the harvest conditions, which can be operated in at least two different operating modes, wherein the cutting unit (1) includes a first sensor assembly (1) disposed on the cutting unit (1) that can be deactivated, which is for operating the cutting unit (1) in a first operating mode, and a second sensor assembly (17) for operating the cutting unit (1) in a second operating mode, wherein, when switching between the at least two operating states, the first sensor assembly (13) or the second sensor assembly (17) is activated without interruption in operation, to execute a distance determination, depending on the selected operating mode.
