Coordinated linkage system for a work vehicle
A work vehicle with a tool pivotally attached to a linkage, an actuator for controllably moving the tool about its pivot, and a tilt angle sensor for sensing the absolute angle of the work tool relative to the earth. A controller is adapted to perform an auto-hold function for the tool, automatically maintaining an initial tool orientation by commanding movement of the tool actuator to hold the work tool at about the initial or set absolute angle of the tool. The controller is adapted to discontinue the tool auto-hold function when the operator manipulates a tool command input device affecting tool actuator movement, and resume the tool auto-hold function at the new orientation affected by the operator. Manipulation of an auto-hold command input device allows the operator to selectively enable and disable the tool auto-hold function.
