An agricultural machine, comprising: - a pair of front wheels (12) and a pair of rear wheels (14), rigidly connected to a main frame (16), - a control cab (18) mounted on the main frame (16), and - suspension means placed between the cab (18) and the main frame (16). Said suspension means comprise a plurality of actuators (20; 30, 32) for controlling the rotation of the cab (18) with respect to the main frame (16) about at least two axis orthogonal to each other. An electronic control unit (24) is provided with sensor means for detecting variations of the cab tilt angle with respect to an horizontal reference direction. The electronic control unit (24) is programmed for controlling said actuators so as to maintain a constant orientation of the cab (18) with respect to said reference direction.
