A movement system for farming machinery includes a transmission box inserted in the rotation group which, due to the action of a rigid arm, causes a lateral translation movement and, due the action of the rotation group, a rotation movement of the functional head around the center of rotation. The rotation group is positioned with respect to the functional head to translate along the trajectory. The functional head is arranged in a collapsed configuration so the functional head is situated within the overall road size determined by the tractor； and to assume a translated configuration, in which the functional head is situated outside the overall road form of the tractor； the rotation movement allows full rotations of 360° of the functional head due to the coincidence of the center of rotation with the axis of rotation of the transmission box.
