A system for hydraulically leveling a multi-wing agricultural implement having a pressure regulating valve and a folding valve fluidly coupled in parallel between a supply line, configured to provide a supply pressure of hydraulic fluid, and an actuator, configured to move an outer-wing section of the implement between a transport position and a fully-extended position. Specifically, when fluid is supplied to the actuator via the pressure regulating valve, only a portion of the supply pressure is allowed through the pressure regulating valve to the actuator such that the outer-wing section may pivot towards a position where the outer-wing section is substantially level with the inner-wing section. When hydraulic fluid is supplied to the actuator via the folding valve, the outer-wing section is actuated towards the transport position. When hydraulic fluid is supplied to the actuator via the leveling valve, the outer-wing section is leveled relative to the inner-wing section.

A utility vehicle includes a chassis and a work implement movably coupled to the chassis. An operator support is positioned within an operator cab. The operator support includes a seat and a backrest coupled to the seat. A position of the operator support is selectively adjustable relative to the chassis. The utility vehicle further includes a control system in communication with the operator support. The control system includes a sensor operable to sense a position of the work implement relative to the chassis, and a controller including a processor and a memory. The controller is configured to receive a signal from the sensor representative of the position of the work implement. The controller is further configured to generate a signal to automatically adjust the position of the operator support relative to the chassis based in part on the position of the work implement relative to the chassis.

A method for controlling the speed of a work vehicle towing an implement that is movable between a working position, in which ground engaging tools of the implement are configured to perform a field operation, and a transport position, in which the ground engaging tools are raised relative to the ground. The method may include monitoring, with a computing device, an implement weight supported by the implement while the implement is in the transport position. The method may further include comparing, with the computing device, the implement weight to a predetermined threshold weight. Additionally, the method may include, when the implement weight differs from the predetermined threshold weight, adjusting, with the computing device, a maximum speed limit for the work vehicle.

Systems, methods, and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar, for controlling operative height of a toolbar and sections of a toolbar and for folding a toolbar between a work position and a transport position. A ground engaging wheel and an actuator are coupled to the toolbar. In one embodiment, a fluid control system is responsive to a command signal to modify the actuator pressure such that the actuator pressure corresponds to a desired pressure.

An agricultural implement includes a transversely extending frame forming a first, a second, and a third frame section. A first actuator is coupled to the first frame section, a second actuator coupled to the second frame section, and a third actuator coupled to the third frame section. Sensors are coupled to each frame section to detect a height of the respective frame section relative to an underlying surface. A control unit is disposed in electrical communication with the sensors and operably controls the actuators to adjust the height of each frame section.
