Abstract
A motor grader having an articulated frame that includes a first front frame portion and a second rear frame portion that is angularly moving with respect to the first frame portion around a pivoting axis. A front steering system includes front wheels that are movable around a steering axis with respect to the articulated frame and around leaning axis transversal to the steering axis so that the front wheels may turn and lean during steering operation. A control unit receives as an input a control signal representing a steering angle and outputs steering actuation commands for an hydraulic actuating system of the front steering system and for a hydraulic actuating system of the articulated frame realizing synchronized and proportional angular movements of the front wheels around the steering and leaning axes and of the first and second portions of the frame around the pivoting axis.
