Abstract: An agricultural machine, comprising a pair of from wheels and a pair of rear wheels, rigidly connected to a main frame, a control cab mounted on the main frame and suspension means placed between the cab and the main frame. Suspension means comprise a plurality of actuators for controlling the rotation of the cab with respect to the main frame about at least two axis orthogonal to each other. An electronic control unit is provided with sensor means for detecting variations of the cab tilt angle with respect to an horizontal reference direction. The electronic control unit is programmed for controlling said actuators so as to maintain a constant orientation of the cab with respect to said reference direction.

Abstract: A braking control system for agricultural tractors wherein individual front and rear wheel hydraulic brakes are operated by a hydraulic braking control unit which is controlled by an electronic control unit to cause it to vary the braking pressure to the individual brakes relative to a reference value set by operation of a brake operating pedal by the tractor operator. The braking control unit varies the braking pressure at the individual wheel brakes in dependence on the associated wheel speed and the tractor ground speed.

Abstract: A braking control system for agricultural tractors comprises:of the type having a pair of front wheels and a pair of rear wheels with at least one pair being driven through a differential and wherein individual wheel brakes are individually controlled through a hydraulic braking control unit which in turn is controlled by an electronic control unit which causes the braking control unit to apply braking pressure to slow the wheels on the inside of the steering bend in response to signals received by a steering angle sensor.
