PROBLEM TO BE SOLVED: To stably perform the horizontal maintenance of an implement even in a field having much unevenness and easily inclining in left and right. SOLUTION: This automatic rolling control device of a ground working implement of an agricultural working machine is provided with a means for judging whether performing the rolling control of the ground working implement 18 on the basis of an absolute inclining angleθs based on detection by an inclination sensor 14 or performing the rolling control of the ground working implement 18 on the basis of a relative inclining angleθk based on detection by an angular velocity sensor 16 or on the basis of a target angleθt of the implement obtained by adding the relative inclining angleθk of the angular velocity sensor 16 to the absolute inclining angleθs. The device performs the rolling control by outputting an actuating pulse signal to a rolling cylinder 9 based on the detected value of inclination of the angular velocity sensor 16 on detecting the inclination of the traveling machine body based on the judging result of the judging means, is constituted to perform the rolling control by continuously outputting the actuating pulse signals to the rolling cylinder 9 by the detected value of inclination of the inclination sensor 14, and makes the ON time of output pulse in the controlling time of the angular velocity sensor 16 longer than the ON time in the controlling of the inclination sensor 14.
