The great versatility and working speed of the machine partly depend on the possibility of opening the external arm 180°, permitting a fast and easy positioning and, most of all, enabling the machine to continue mowing with the internal disc while the external one, by lifting up, can pass over road or advertising signs that may be present along the way, while automatically interrupting the rotation of the blades.
