ABSTRACT:
In combination with a conventional laser beam control system for controlling an earth scraping and storing apparatus, such as a box blade for example, for leveling terrain, an improvement detecting when the box blade is full and overflowing is imminent and sensing the level of the box blade relative to the ground. The improvement overrides the functions of the conventional laser beam controls, when desirable, whereby overfilling and bogging down of the box blade is prevented and whereby rough terrain is readily and effectively leveled.
