Abstract:
A system, method, and apparatus includes measuring wear of a cutting edge of a blade of a work vehicle. Blade position or calibration measurements are made with or without a cutting edge. A wear condition of the cutting edge is acceptable when the blade position measurement less an acceptable wear to the cutting edge amount is less than a blade calibration measurement. A wear condition of the cutting edge is unacceptable when the blade position measurement less an acceptable wear to the cutting edge amount is greater than a blade calibration measurement. Alternatively, a wear condition of the cutting edge is unacceptable when a blade calibration measurement plus a tolerance margin is greater than the blade position measurement. The wear condition of the cutting edge is acceptable when the blade calibration measurement plus a tolerance margin is less than the blade position measurement.
