CHARACTERISTICS: CBM quick couplings with safety device, for three-point hitches on agricultural tractors, make it possible to hitch working equipment directly to the tractor from the driver's seat with the use of just one person, in less time than traditional ones and in conditions of absolute safety and comfort for the operator. The new lower link hooks are equipped with an Automatic Anti-Lock System. A device placed inside the hook locking tooth prevents, under no circumstances, the accidental opening of the hook after the kneecap is in place. With this new patented system, only by acting on the unlocking lever, which is controlled from the tractor driver's seat, is it possible to open the hook and detach the implement.
