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, at least one additional section, and at least one coupling assembly that removably connects the center section to the at least one additional section. The at least one coupling assembly includes at least one actuator connected to the center section and the at least one additional section. The at least one actuator is located underneath the pivot point. The at least one additional section is configured for being coupled to the center section in harvesting of a crop material and decoupled from the center section and subsequently towable in transportation of the sectional header system.

An agricultural vehicle header having a base structure, a header wing section, an articulated joint connecting the header wing section to the base structure, an actuator, a load sensor, and a controller. The actuator is configured to move the header wing section relative to the base structure between a wing lowered position and a wing raised position the load sensor is operatively connected to the header wing section. The controller is configured to acquire load sensor data from the load sensor to evaluate a magnitude of a gravitational load on the header wing section, and prevent the actuator from moving the header wing section towards the wing raised position if the magnitude of the gravitational load exceeds a predetermined threshold load value. An agricultural combine having the header and methods of operating the same are also provided.

An agricultural vehicle header having: a frame, a support arm having a proximal end rotatably mounted by a support arm pivot to the frame and a distal end spaced from the proximal end, a torque transfer anchor rigidly attached to the frame, a support torque rod having a distal end rotationally fixed to the support arm, and a proximal end rotatably mounted to the torque transfer anchor to rotate about a first axis, a frame torque rod having a proximal end rotatably mounted to the torque transfer anchor to rotate about a second axis and a distal end rotationally fixed to the frame, and a drive linkage connecting the support torque rod to the frame torque rod at the torque transfer anchor, to transfer a rotational motion of the support torque rod about the first axis into an opposite rotational motion of the frame torque rod about the second axis.

An agricultural header includes a header frame and at least one harvesting element carried by the header frame. The header frame includes a rigid portion, a first conformable portion flexibly coupled to the rigid portion by a first resilient material that allows at least about 1.5° of reversible deflection, and a second conformable portion flexibly coupled to the rigid portion by a second resilient material that allows at least about 1.5° of reversible deflection.

A cutting device is embodied for cutting agricultural crop plants by a rotational movement about a cutting rotation axis and has at least one knife element that, in a plan view of a top side of the cutting device, is embodied open in circulating direction. At least one radial conveying element, arranged at least at the top side and stationary relative to the knife element, is provided that at least in sections thereof is embodied for conveying the crop plants in a conveying direction that, relative to the cutting rotation axis, is oriented partly tangentially and partly radially relative to the cutting rotation axis. Moreover, a harvesting attachment with a plurality of such cutting devices and a field chopper with such a harvesting attachment is provided.

A work vehicle system includes a work vehicle controller configured to output a control signal indicative of instructions to move a feeder house based at least in part on at least one header parameter. The work vehicle controller is configured to output the control signal to a network. The work vehicle also includes an agricultural header controller configured to receive the control signal and control movement of the feeder house based at least in part on the control signal. Further, the work vehicle includes a wing controller configured to receive the at least one header parameter from the network and output a wing control signal indicative of instructions to move a wing based at least in part on the at least one header parameter. The wing is coupled to a center section.

An agricultural harvester includes a controller configured to receive at least one wing angle signal indicative of an angle at least one wing with respect to a center section of a header. The controller is also configured to receive a wing height position signal indicative of a distance between the at least one wing and a soil surface, determine whether the angle of the at least one wing exceeds an angle limit threshold based at least in part on the wing angle signal, and output a tilt signal to a tilt actuator in response to determining the angle of the wing exceeds the angle limit threshold. The tilt signal is indicative of instructions to maintain the distance between the at least one wing and the soil surface within a target distance threshold.

An agricultural header includes: a main section including a main frame carrying at least one cutting element; at least one wing section pivotably coupled to the main section and including a wing frame; and a linkage pivotably coupling the at least one wing section to the main section, the linkage including an upper bar and a lower bar which are both coupled to the main frame and the wing frame, the upper bar defining an upper bar axis and the lower bar defining a lower bar axis which is non-parallel to the upper bar axis.

A header of an agricultural harvester is provided. The header includes a rigid modular frame. The rigid modular frame includes a center section, a first outer section, and a second outer section. The first and second outer sections flank the center section and are rigidly coupled to the center section.

A control system and method for operating an articulating header of a combine harvester in a failsafe mode. The method includes monitoring the articulating header, alerting a user when a fault condition is detected in the articulating header, and converting the articulating header to a non-articulating header in response to the fault condition so that the combine harvester may be operated in a failsafe mode.
