摘要： A harvester includes a frame and a header coupled to the frame. The header includes a center segment, a wing coupled to the center segment, and an actuator between the wing and the center segment. The wing includes a ground-engaging component configured to bear a first variable portion of the weight of the wing and a wing sensor coupled to the wing. The actuator is configured to transfer a second variable portion of the weight of the wing to the frame. A controller is configured to receive a signal from the wing sensor and to send a signal to the actuator to vary a ratio of the first variable portion of the weight of the wing to the second variable portion of the weight of the wing.

摘要： A header has a position controlled gauge wheel that is controlled using a position actuator. The position actuator is locked when the gauge wheel is in a selected position, relative to a mainframe of the header. An operator input, changing the position of the header, is detected and the position actuator is unlocked to accommodate movement of the header, based on the detected operator input signal.

摘要： A harvesting platform includes a first section and extends along a first section plane that is substantially parallel to a ground surface along which the harvesting platform moves with a combine. A second section is connected to the first side of the first section, and rotates with respect to the first section within a range of angular positions. A locking mechanism retains the second section in a position with respect to the first section while activated, and permits movement of the second section with respect to the first section while deactivated. A controller receives a first signal indicative of the position, and sends a second signal to deactivate the locking mechanism in response to the position being at a positive non-parallel angle with respect to the first section plane. The second section moves toward the first section plane in response to gravity while the locking mechanism is deactivated.

摘要： A wing locking system for a harvesting header is provided. The wing locking system includes an accumulator, a fluid cylinder operably attached to a wing of the harvesting header, a hose fluidly connecting the accumulator and the fluid cylinder, and a valve operably disposed between the accumulator and the fluid cylinder. The valve includes a first selectable position configured to permit a first fluid flow rate between the accumulator and the fluid cylinder and a second selectable position configured to permit a second fluid flow rate from the accumulator to the fluid cylinder. The first fluid flow rate is greater than the second fluid flow rate.

摘要： A combine draper header and method of floating a wing of the same from a center section of the draper header. The wing is movably supported with respect to the center section to enable movement of the wing between a first position and a second position. The wing is supported with respect to the center section with a resilient float element. Increasing amounts of energy are stored in the resilient float element through movement of the wing from the first position to the second position. The resilient float element is re-oriented with a float linkage to reduce the mechanical advantage of the resilient float element for supporting the wing through movement of the wing from the first position to the second position, thus buffering the wing from a force increase from the resilient float element.

摘要： Systems and apparatuses for articulating float arms of a harvester header between a flexible configuration and a rigid configuration are disclosed. The systems and apparatuses include a locking tube that experiences no torque or approximately no torque when the float arms are in the rigid configuration. Further, the systems and apparatuses also avoid adjustments to ensure that float arms are fully retracted, such as into abutting contact with another portion of a header.

摘要： A header assembly for an agricultural harvesting machine comprises a first frame assembly, a second frame assembly that supports a cutter, and is movable relative to the first frame assembly, a float cylinder coupled between the first frame assembly and the second frame assembly, an accumulator, a controllable reservoir, and fluidic circuitry. The fluidic circuitry comprises a first conduit forming a first fluid path that provides a flow of pressurized fluid under pressure to the float cylinder, so the float cylinder exerts a float force on the second frame assembly, a valve mechanism that is actuatable to inhibit fluid flow along the first fluid path between the accumulator and the float cylinder, a second conduit forming a second fluid path fluidically coupled to the controllable reservoir, the controllable reservoir being controllable to add fluid to the float cylinder.

摘要： A harvesting platform is connected to a combine for movement with the combine over the ground surface. The harvesting platform includes a cutter bar that cuts a crop being harvested, and a reel that presses the crop against the cutter bar during harvesting. The cutter bar moves between a cutter bar harvesting position and a cutter bar transport position, and the reel moves between a reel harvesting position and a reel transport position. A controller receives a first signal from a user via a user interface, sends a second signal to the cutter bar to move the cutter bar between the cutter bar harvesting position and the cutter bar transport position in response to the first signal, and send a third signal to the reel to move the reel between the reel harvesting position and the reel transport position in response to the first signal.

摘要： A system for a header assembly that has a center frame configured to pivot relative to an adapter frame about at least one center axis, a center actuator coupled to the center frame to selectively provide a biasing force thereto, a first arm assembly configured to pivot relative to the center frame about at least a first arm axis, a first actuator coupled to the first arm assembly to selectively provide a biasing force thereto, a controller in communication with the center actuator and the first actuator to selectively alter performance characteristics of the center actuator and the first actuator, and a user interface in communication with the controller and having at least a first option and a second option. Wherein, the controller adjusts the performance characteristics of both the center actuator and the first actuator when the user interface is transitioned between the first option and the second option.
