Abstract:
An agricultural machine, comprising:a pair of rear wheels, rigidly connected to a main frame, and a pair of front wheels connected to the main frame by means of a front axle;a control cab mounted on the main frame; andsuspension means placed between the cab and the main frame, said suspension means including a plurality of actuators adapted to control the rotation of the cab with respect to the main frame about at least two axis orthogonal to each other; andan electronic control unit provided with sensor means for detecting variations of the tilt angle of the cab with respect to a horizontal reference direction, the electronic control unit being programmed for controlling said actuators so as to maintain constant the orientation of the cab with respect to said horizontal references direction;wherein said sensor means are not effected by variations of the cab tilt angle due to either transversal or longitudinal acceleration of the machine.
