PURPOSE: To provide a rolling control mechanism capable of suppressing occurrence of shock and overshoot caused by abrupt working as much as possible.
CONSTITUTION: In a rolling control mechanism for a ground working device provided with a control device 10 for regulating a rolling cylinder in such a way that a tilting device 3 is connected to a traveling device in a freely driving and rolling way by a rolling cylinder 5 and a target working amount obtained based on detected information of an inclination sensor 14 for discovering the right and left inclination angles of the traveling machine body is coincident with an actual working amount detected by a stroke sensor 15, the control device 10 operates the target working speed of the rolling cylinder 5 based on predetermined map data by deviation of the target working amount from the actual working amount and change ratio of the detected value of the inclination sensor 14 and regulates the rolling cylinder to make the working speed obtained based on the detected value of the stroke sensor 15 reach the target working speed.
