PROBLEM TO BE SOLVED: To automatically position a blade of a motor grader at a memorized location. SOLUTION: This system is provided with an electronic control device 64 and a blade control 60 having a position sensor 78. Output of a position sensor 78 is observed to fix a position of a blade control. Next, a first signal for setting a memorized blade position is received, and the memorized blade position is decided on the basis of a signal from the position sensor 78. Next, a second signal for demanding the memorized blade position is received, and a present blade position is decided on the basis of output from the position sensor 78. Next, a control signal for operating the blade control 60 is generated so that a blade is moved to the blade position to be memorized from the present blade position.
