Abstract: An agricultural machine includes a main frame, a rockshaft pivotably coupled to the main frame, a lift actuator couple between the rock shaft and the main frame, a lift arm pivotably coupled to the main frame below the rockshaft, a lift strap coupled between the rockshaft and the lift arm, and a lift actuator coupled between the main frame and the lift strap to pull the lift arm upwards. The agricultural machine includes header, which is supported by the lift arm and the float actuator above the ground at a desired harvesting height. During harvesting, the lift arm may encounter uneven ground, causing the header to move away from the desired harvesting height. By measuring float actuator pressure or header position and by changing the pressure in the float actuator or lift actuator in response, the header can be rapidly returned to the desired harvesting height.

Abstract: A work implement includes a support controller disposed in communication with a hydraulic lift cylinder. The support controller initiates a control activation signal for commanding movement of the hydraulic lift cylinder to move the head support from an initial start position to a commanded support position. The support controller determines a stop signal position based on the current rate of movement of the head support toward the commanded support position. The stop signal position may further be based on a current fluid pressure of an associated float system. The support controller ceases or stops the control activation signal when the head support reaches the stop signal position, whereby the head support decelerates over a distance after cessation of the control activation signal such that the head support substantially stops movement at the commanded support position.

Abstract: A method of defining an end travel limit of an electric actuator includes sensing an electric current of the electric actuator while moving the electric actuator from a first position to a second position. A maximum travel current of the electric current sensed during movement of the electric actuator between the first position to the second position is increased by a factor to define a maximum calibration current. The electric current is then sensed while moving from the second position toward an end travel position of the electric actuator. Movement of the electric actuator is stopped at a fault position when the electric current equals the maximum calibration current. The end travel limit of the electric actuator is then defined as a function of the fault position.

Abstract: Systems and methods for controlling formation of a windrow in response to a single control input are disclosed. The single control input represents a desired windrow width. The single control input is used to determine positions of components of a cutter implement, such as side shields and a swath flap, that are used to form a windrow having the desired windrow width represented or that is otherwise associated with the single control input.

Abstract: A crop windrow monitoring system includes an image sensor positioned to include a field of view facing a rearward direction of a power unit, and a visual monitor operable to display an image. A computing device is operable to determine an intended direction of movement of the power unit. The image is displayed on the visual monitor in a first mode having a first magnification when the intended direction of movement includes the rearward direction. The image is displayed on the visual monitor in a second mode having a second magnification and overlaid with indicia indicating a width of the windrow when the intended direction of movement includes the forward direction. The second magnification may be larger than the first magnification.

Abstract: A forming shield arrangement configured for a windrowing work vehicle is supported for movement by a support structure. The forming shield arrangement is configured to at least partly shape a windrow of a crop material. A method of operating the forming shield arrangement includes receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the forming shield arrangement relative to the support structure. The method also includes processing, by the processor, a positioning control signal based, at least in part, on the stored position setting. Moreover, the method includes changing, with an actuator, the position of the forming shield arrangement according to the positioning control signal.

Abstract: A steering system and method for a vehicle having steerable front and rear wheels has rear hydraulic steering device that may be coupled to one or more of the rear wheels. A rear valve assembly may hydraulically control the rear hydraulic steering device to steer the rear wheels based upon a rear steering command from a controller. In a manual steering mode, the controller does not determine a rear steering command for the rear valve assembly such that the rear wheels are freely rotatable. In a rear steering assist mode, the controller determines the rear steering command based upon, at least in part, the manual steering input.
