The Vevor PTO slip clutch is designed to protect your tractor and implement drivetrain by limiting torque transfer and allowing the two sides of the PTO shaft to rotate at different speeds when needed. Made from 20CrMnTi carburized steel with a painted black finish, it is built for durability and resistance to impact and wear. Its 1-3/8" 6-spline male and female ends fit standard PTO shaft connections, while the adjustable spring tension supports a 20-55 horsepower range. The clutch uses replaceable friction discs for easier maintenance and long-term use. It is suitable for rotary cutters, brush cutters, rotary mowers, and similar tilling attachments.
