摘要： An agricultural vehicle having a chassis, wheels, a power unit, and a header. The header has a center section, at least one wing section extending laterally from the center section, and a wing section support. The center section is movable relative to the chassis, the wing section is movable relative to the center section, and the wing support is movable relative to the wing section. The combine has a control system that is configured to determine that the combine is configured to drive at a road-driving speed, and in response to such determination: operate a center section actuator to move the center section to a raised center section position, operate a wing section actuator to move the wing section to a raised wing section position, and operate a wing support actuator to move the wing support to a raised wing support position.

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 header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

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： An agricultural harvester comprises a feederhouse pivotally attached to a chassis, where the feederhouse defines a conduit for conveying crop material rearwardly from a front opening. A header interface frame is pivotally mounted to the feederhouse over the front opening to permit header pitch adjustment around a pitch adjustment axis. Upper and lower linear actuators are connected on one side of the feederhouse between the feederhouse and interface frame to control the pitch adjustment.

摘要： One embodiment includes a grading tool structured for attachment to a work machine. The grading tool includes a frame, ground contacting wheels coupled with the frame, a comb coupled with the frame and extending from a first end of the frame, and a coupling member coupled with the frame and structured to be accessible from a second end of the frame. When the ground contacting wheels are in contact with the ground a depth of penetration of the comb into the ground surface is adjustable by changing the pitch of the grading tool.
