Abstract :In the trials of the present work, a double-axle trailer with a carrying capacity of 6 tons and a hydraulically effective mechanical brake were used as a tractor towed car. There is a hydraulic brake system on each axle of the agricultural trailer. In order to separate the brake system on the axles from each other, a hydraulic mechanically controlled 2/2 directional control valve was mounted on both hydraulic brake system inlets. The study was carried out at constant speed insert ignore into journalissuearticles values(25 km h-1);, on stabilized road conditions, with 4 different braking modes and 4 different trailer loads. On stabilized ground, the braking acceleration insert ignore into journalissuearticles values(deceleration); of the tractor insert ignore into journalissuearticles values(without trailer); is 5.51 m s-2. The braking acceleration of the combination is 2.15 m s-2 under the condition that the trailer\`s carrying capacity was 30% more loaded and without brakes, and the braking acceleration of the combination was 3.26 m s-2 when braking on both axles insert ignore into journalissuearticles values(4 wheels);. The deceleration of the combination was above 3.5 m s-2 under the condition of braking on both axles at the rated load of the agricultural trailer, while it was below the standard value in other braking approaches.
