Motor grader cutting edge wear calibration and warning system

A method for measuring wear of a cutting edge of a blade of a work vehicle, the method comprising:

• providing the work machine with a circle side shift cylinder, a controller, and a blade position sensor system;
• measuring a calibration position measurement of the blade with the cutting edge attached thereto and the circle side shift cylinder, while the blade and the circle side shift cylinder are in a measurement position;
• at a later point in time after the measuring the calibration position measurement is performed, moving the blade and the circle side shift cylinder to the measurement position that corresponds to the calibration position measurement of the blade;
• after the moving of the blade and the circle side shift cylinder to the measurement position, measuring a blade position measurement of the blade and the circle side shift cylinder in the measurement position;
• upon comparison of the blade position measurement to the calibration position measurement, determining a wear condition of the cutting edge of the blade as either acceptable wherein the cutting edge does not require replacement or unacceptable wherein the cutting edge does require replacement;
• and
• automatically limiting productive movement of the blade wherein the blade is only operable to perform a non-grading operation when the unacceptable wear condition is satisfied.
