PURPOSE:To perform an easy and accurate work to level the ground, by a method wherein a road surface finishing angle is computed and displayed through a detection of a blade inclining angle, an articulate working angle, a circle crossfeed angle, and a circle rotary angle. CONSTITUTION:A blade inclining angle (a) of a grader is detected by a sensor 11, an articulate working angled d by a sensor 12, a circle crossfeed angle e by a sensor 13, and a circle rotary angle f by a sensor 14. Each angle so detected is A-D-converted to input the signal to a microcomputer 16. The signal is computed by an inequality of tan c (sin)/{cos(d+e+f)}, and a road surface finishing angle c is counted to display it in an indicator 17. This permits even a beginner to perform a precise ground-levelling work through a watching of the indicator.
