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.

The present invention relates to a method for operating an attachment arranged on a pick-up apparatus of a self-propelled combine harvester, wherein the attachment comprises a central portion and two side portions which are each connected to the central portion by a frame joint so as to be pivotable about a pivot axis oriented in the direction of travel, wherein the respective side portion is pivotable about the pivot axis transversely to the direction of travel relative to the central portion by means of an actuator that is activated by a control apparatus, wherein a vertical distance of the attachment from the ground is adaptively set by at least one hydraulic cylinder on the pick-up apparatus, wherein, for the ground guidance of the attachment, the positioning of the side portions relative to the central portion is controlled or regulated independently of vertical and transverse guidance, activated by the combine harvester, of the attachment.

A piston lock system having first and second cylinders, first and second pistons telescopically connected to the cylinders, and first and second piston locks. The piston locks are movable in a transverse direction within a planar region between the cylinders, between unlocked positions in which the piston locks are not located between the free ends of the cylinders and the free ends of the piston, and locked positions in which the piston locks are located between the free cylinder ends and the free piston ends. A control link is operatively connected to the piston locks, and configured to simultaneously move the piston locks between the locked and unlocked positions.

A piston lock system comprising: a cylinder, a rod receiver fixed to the cylinder, a piston slidably mounted to the cylinder, and a rod fixed to a free end of the piston and extending parallel to the piston to be located within the rod receiver. The piston and rod are movable relative to the cylinder and rod receiver between a retracted position and an extended position. A lock pin is mounted to the rod receiver and movable between a unlocked position in which the lock pin does not intersect a path of the rod, and a locked position in which the lock pin intersects the path of the rod and prevents the rod and piston from moving to the retracted position. Lock pins of multiple actuators can be connected to operate in unison.

A method and apparatus for controlling a header height of a combine harvester that includes a header, a ground speed sensor, a ground height sensor configured to detect a ground contour directly beneath the header, a forward looking sensor (FLS) configured to detect a ground contour forward of the header, and a controller. The controller receives signals from the ground speed sensor, the ground height sensor and the FLS, and calculates a header height output as a function of (i) an output of the ground speed sensor, which represents a ground speed of the combine, (ii) an output of the ground height sensor, and (iii) an output of the FLS. The controller is further configured to weight the outputs of the ground height sensor and the FLS as a function of the speed of the combine harvester in calculating the header height output.

An arrangement for triggering an actuator for adjusting an adjustable element of an agricultural working machine comprises: a specifying device for generating adjustment commands for the adjustable element; a control arrangement for the actuator; and a signal-shaping unit which, upon receipt of an adjustment command, initially applies a first signal dependent on the adjustment command to the control arrangement, and then applies a second signal, which is dependent on the adjustment command and delayed in time relative to the first signal, the second signal leading to a reduction or cancellation of a natural oscillation generated by the first signal in the system consisting of working machine and element.

A crop divider includes a housing including an interior cavity and an adjustment assembly disposed within the interior cavity of the housing. In an embodiment, the adjustment assembly is configured to adjust a height of the housing relative to ground. In an embodiment, the adjustment assembly includes an adjustment handle disposed within the interior cavity and a pivot disposed vertically above the adjustment handle within the interior cavity of the housing. In an embodiment, the housing is configured to rotate about an axis through the pivot in response to rotation of the adjustment handle.

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.

An agricultural vehicle including a chassis and a header carried by the chassis and including a cutter mechanism. The header is adjustable in a vertical direction. The agricultural vehicle also includes a header actuator connected to the header and configured to adjust the header in the vertical direction, and a controller coupled to the header actuator. The controller is configured for receiving an input command for controlling an operation of the header actuator to achieve a lifting height, operating the header actuator in conformance with the input command, and terminating the operating of the header actuator.

In a combine harvester, the header (1) is lifted up by the feeder (8) and secured thereto by a mechanism including a pair of securing pins (23) on the feeder's carrier structure (20,21). The securing pins are provided with stops (35) protruding towards the header and which include a sloped surface, configured to interact with positioning aids (39) on the header. The lateral outward or inward movement of the securing pins (23) is driven by a centrally placed actuator (24). As the actuator is extended, the positioning aids (39) roll or glide down the sloped surfaces, enabling a gradual approach of the header towards the feeder, up to a point where the securing pins (23) become aligned with slots (50) on the header. Continued actuation of the pin motion then establishes the securing of the header to the feeder.
