PROBLEM TO BE SOLVED: To provide a paddy field working implement connected to a traveling body, which paddy field implement is rolling-controlled with excellent response and high accuracy. SOLUTION: The mechanism is equipped with an angle sensor 27 detecting lateral tilting angle and an angular velocity sensor 28 detecting lateral tilting angular velocity on a paddy field working unit, and has a tilting angle calculating means for adding low frequency component of detected signal from the angle sensor 27 to a high frequency component of tilting angle obtained by integrating the detected signal from the angular velocity sensor 28 so as to obtain a lateral detected tilting angleθof the paddy field working implement, and has a control means for operating and controlling a driving mechanism for rolling to bring a calculated tilting angleθclose to a target tilting angleθ0.
