Abstract: A graphical grade indicator for use in earth moving operations has an improved, variable resolution and a substantially unlimited range. This grade indicator results in a more accurate indication of the position of a cutting blade relative to the desired grade and, as a result, allows a machine operator to more accurately control grading operations. In one embodiment, a graphical grade indicator has a graphical scale with a substantially unlimited range and various indications indicating a desired grade level and at least a first undesirable grade level. When the cutting blade deviates from the desired grade level, a first indication is provided indicating, illustratively, the direction and magnitude of movement of the cutting blade repositioning necessary to achieve the desired grade. The resolution of the graphical scale can be changed in order to provide a desired degree of accuracy in grading operations.
