The disclosure relates to a device of a vehicle, in particular a tractor, having a hydraulic activation unit for controlling the operation of a towed implement on the vehicle, comprising at least one position detection unit with at least one camera, position detection marks, and an evaluation unit and a data-transmitting connection to a control unit which is assigned to the hydraulic activation unit. Furthermore, a method is proposed, wherein by means of such a position detection unit the position of the towed implement can be determined, and the position can be adjusted according to requirements by suitable operation of the hydraulic activation unit.

A work machine according to the present invention includes a manual operating tool configured to operate a hydraulic actuator; an operation amount detector configured to detect an operation amount of the manual operating tool; a hydraulic pump configured to generate a hydraulic pressure to be supplied to the hydraulic actuator; an electric pump motor configured to change an output characteristic of the hydraulic pump in response to a rotary force to be given to the hydraulic pump; a motor load detector configured to detect a motor load of the pump motor; and a pump motor controller configured to determine a necessary output characteristic based on the operation amount and the motor load and control the pump motor based on the output characteristic.

A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

An arrangement for operating a hydraulic control valve for an agricultural tractor includes a first hydraulic connection and a second hydraulic connection of the hydraulic control valve alternately acting as a feed line or return line for hydraulic fluid depending on an operating command, a first and second hydraulic coupler for operating a hydraulic consumer attachable thereon, and a 3/2-way valve selectively connects the first hydraulic connection to a working chamber of a hydraulic cylinder in a first switching position and to the first hydraulic coupler in a second switching position, wherein the second hydraulic connection is connected directly to the second hydraulic coupler.

A working vehicle includes a vehicle body, a traveling device to support the vehicle body such that the vehicle body is allowed to travel, and a height changing mechanism to change a height of the vehicle body that is a distance of the vehicle body from a ground surface. The height changing mechanism is configured to change the height of the vehicle body to any height between a first height and a second height higher than the first height.
