摘要： A crawler vehicle has a frame (2) ; a working tool (8) hinged at the back of the frame (2) around a yaw axis (A3); and actuation system (9), which is configured to act between the working tool (8) and the frame (2); and a control device (16), which is configured to calculate a value of the steering radius of the crawler vehicle (1) and to control the actuation system (9) so as to selectively: allow the working tool (8) to freely oscillate about the yaw axis (A3) when the calculated value of the steering radius is comprised within a reference interval; keep the position of the working tool (8) blocked with respect to the frame (2) when the calculated value of the steering radius is outside the reference interval.
