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.
