SERVICE INFO TB1082
What is safety P.T.O ? Application: Tractors from 20 to 95kW To include: CNH, John Deere, AGCO, Claas Renault & Steyr LuK safety PTO clutches perform the same function as a standard LuK dual clutch with two independently actuated clutches in one assembly. In a safety PTO clutch, the PTO lever action works the opposite way to a conventional dual clutch. Depressing the levers forces the pressure plate against the flywheel, trapping the PTO disc and creating drive at the PTO output shaft. The PTO disc is normally held disengaged at all times, and can only be engaged by the operator moving a mechanical lever.
