Abstract:
1. A system for automatically raising a stabilizer of a work vehicle, comprising a proportional control operator input device configured to signal both a plurality of upward stabilizer raising rates and a plurality of stabilizer lowering rates; at least one electronic controller configured to receive a signal indicating a commanded raising rate and a commanded lowering rate from the input device; and at least one hydraulic valve coupled to the controller to raise and lower the stabilizer in response to rate signals received from the controller; wherein: the controller has a first mode of operation in which it signals the at least one valve to raise and lower the stabilizer proportionate to the position of the input device; the controller has a second mode of operation in which it automatically raises the stabilizer to a predetermined higher up position; and the controller is configured to change from the first mode of operation to the second mode of operation based upon the operator's positioning and holding the input device in a single position of a range of positions for a period of time.
