The Vevor PTO slip clutch is built for tractor and implement protection by limiting transferred torque and allowing the PTO shaft ends to spin at different speeds when needed. It features durable 20CrMnTi carburized steel construction with a painted black finish for strength and wear resistance. The clutch uses 1-3/8" round male and female ends, adjustable tension springs, and replaceable friction discs for adaptable operation. With a rated torque of 900 nm and a 20-55 horsepower adjustment range, it is suited for rotary cutters, mowers, brush cutters, and similar attachments.
