PROBLEM TO BE SOLVED: To provide an agricultural working vehicle preventing its control from getting instable with the tractor body as a swing source and also controllable through sensing the unevenness of farm surface in high accuracy by making the best use of the high responsiveness of an angular velocity sensor. SOLUTION: The agricultural working vehicle 1 is equipped with an angular velocity sensor 19 for detecting the speed of the change in the transverse tilt angle of the vehicle 1, and a control means 60 for controlling the relative angle of the vehicle 1 to a ground working apparatus 14 based on the detection values given by the above angular velocity sensor 19. In this vehicle 1, the control means 60 acts so as to make a relative angle control for reducing the angular velocity by the posture change of the ground working apparatus 14 and includes such a means A as to reduce the influence of the detection values given by the angular velocity sensor 19 to the relative angle control of the ground working apparatus 14 when the detection values given by the angular velocity sensor 19 represent levels greater than a threshold value at a given frequency or higher within a given period of time.
