SYSTEM AND METHOD FOR CONTROLLING THE POSITIONS OF AN IMPLEMENT AND MARKERS ON A WORK VEHICLE

摘要

An apparatus and method for controlling positions of an implement and a marker associated with a work vehicle are disclosed. The apparatus includes a hydraulic circuit coupled to a first cylinder that governs the position of the marker, a first valve coupled to a second cylinder that governs the position of the implement and also coupled to a first port of the circuit, and a second valve coupled to a second port of the circuit. The circuit is configured to isolate the first port of the circuit from secondary pressure supplied to the second port by way of the second valve, and further configured to isolate the primary port of the circuit from primary pressure supplied to the first port by way of the first valve. The primary pressure influences movement of both the marker and the implement, while the secondary pressure influences movement of the marker only.
