An agricultural machine includes a float cylinder interconnecting a header linkage system and a frame of the machine. A first rod side accumulator and a second rod side accumulator are both in fluid communication with a rod side fluid port of the float cylinder. A first accumulator control valve is positioned to control the first rod side accumulator, and is selectively controllable between an open position allowing fluid communication between the first rod side accumulator and the rod side fluid port of the float cylinder, and closed position blocking fluid communication between the first rod side accumulator and the rod side fluid port of the float cylinder. The system provides a slower first float response with the first accumulator control valve open, and a faster second float response with the first accumulator control valve closed.

A method for calibrating a height control system for an implement of an agricultural work vehicle can include providing an input signal to the height control system to adjust a height of the implement relative to the ground surface; monitoring the height of the implement relative to the ground surface; adjusting at least one gain of the height control system; and determining a maximum stability gain of the height control system based on the at least one gain and the monitored height. The maximum stability gain can correspond with a stability point of the height control system at which the height control system transitions from stable to unstable. The method can include setting gain(s) of the height control system based on the maximum stability gain.

A control system for an agricultural system includes a first controller configured to receive sensor information from a plurality of sensors, in which the sensor information is indicative of a height of a header of the agricultural system, and the first controller is configured to convert the sensor information into position data. The control system further includes a second controller communicatively coupled to the first controller, in which the second controller is configured to receive the position data from the first controller, and the second controller is configured to determine a target position of the header based on the position data.

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.

A header assembly for an agricultural harvesting machine having a traction unit comprises a cutter, a main frame that supports the cutter, a float cylinder configured to be coupled between the main frame and the traction unit, an accumulator, and fluidic circuitry that fluidically couples the accumulator to the float cylinder. The fluidic circuitry is configured to provide a first flow of pressurized fluid under pressure to the float cylinder, so the float cylinder exerts a float force on the main frame, and, based on a control input that corresponds to a lifting operation of the header assembly, provide a restricted flow of fluid, that is restricted relative to the first flow, between the float cylinder and the accumulator.

A wheel assembly of a harvester header includes a latch and a pin. The pin is configured to engage the latch while a wheel of the wheel assembly is at a first position and the pin is configured to disengage the latch while the wheel of the wheel assembly is at a second position. Engagement of the pin and the latch is configured to block movement of the wheel relative to a frame of the harvester header.

A header of a harvester includes a header segment, a center section, an actuator coupling the header segment to the center section, and a controller. The header segment includes a cutter bar configured to cut crops and the header segment includes a first portion of a conveyor assembly. The center section includes a second portion of the conveyor assembly, in which the center section is configured to receive crops from the header segment via the first portion of the conveyor assembly, and the second portion of the conveyor assembly is configured to transport the received crops to a crop processing system of the harvester. The controller is configured to receive a signal indicative of a target position of the header segment and the controller is configured to control the actuator to adjust the header segment to the target position.

A header of a harvester includes a first header segment comprising a cutter bar configured to cut crops, and a first portion of a conveyor assembly. The header additionally includes a center section comprising a second portion of the conveyor assembly, wherein the center section is configured to receive cut crops from the first header segment via the first portion of the conveyor assembly. The header also includes a first wheel configured to at least partially support a weight of the header, and a first sensor configured to output a signal indicative of a distance to ground. The header further includes a first actuator coupling the first wheel to the header; and a control system comprising a processor configured to receive a sensor signal from the first sensor and to control the first actuator to adjust the first wheel based on the sensor signal.

An arrangement for controlling the height and/or incline of a combine header for harvesting thin-stemmed crops includes a control system which is connected to a sensor for detecting the height of the combine header above the ground, and to an actuator for controlling the height and/or incline of the combine header and which can be operated to control the actuator in dependence on signals of the sensor. A mulching appliance with a cultivating tool for shredding plant stumps is attached to the combine header in a vertically movable manner following the contour of the ground, and the sensor is set up to detect the position of the mulching appliance relative to the combine header.

An attachment system for an agricultural vehicle including a feeder housing and a header. The attachment system includes at least one feeder connecting member configured for being located on and movably connected to the feeder housing, and at least one header connecting member configured for being located on the header. The at least one feeder connecting member is automatically connectable and securable to the at least one header connecting member as the feeder housing lifts the header.
