ABSTRACT:
A grading control system for a work machine having a work implement for grading along a grade defined by a laser plane generator is disclosed. The system includes tilt and lift actuators associated with the work implement and configured to selectively tilt, raise and lower the work implement. A laser receiver is configured to receive a laser signal indicative of a desired grade. The laser receiver is configured to communicate a height signal indicative of a position of the work machine relative to the laser plane. A lift sensor is configured to communicate a lift signal indicative of a lift position of the work implement. A control module is configured to generate and communicate a control signal based on the height and lift signals to actuate at least one of the lift and tilt actuators to maintain the work implement at a position substantially corresponding to the desired grade.
