Adjustable Rotary Cutter Slip Clutch, Black PTO Slip Clutch with 1-3/8" x 6 Spline Ends – Torque-Limiting Tractor

Prevent costly damage to your PTO shaft with our heavy-duty adjustable rotary cutter slip clutch. Designed to limit excessive torque, this black PTO slip clutch allows the tractor and implement to spin at different speeds, reducing shock loads and extending equipment life.

Premium 20CrMnTi Steel Construction:

Built from reinforced 20CrMnTi carburized steel, this tractor PTO clutch withstands high-impact forces and resists wear. The smooth black-painted surface enhances durability, ensuring reliable performance under heavy use with rotary cutters, brush hogs, and tillers.

Universal 1-3/8" x 6 Spline Compatibility:

Featuring standard 1-3/8" x 6 spline ends, this PTO slip clutch seamlessly connects to most tractor output shafts and implement input shafts. Its shear-bolt-like safety function provides added protection against sudden overloads.

Easy Torque Adjustment (20–55 HP Range):

Customize the clutch’s resistance with simple spring tension adjustments (rated torque: 900Nm). Tighten or loosen the eight nuts in 1/4-turn increments to match your equipment’s needs—ideal for rotary mowers, cutters, and tractors (20-55 HP).

Replaceable Friction Discs for Longevity:

The modular spring-and-disc design includes replaceable friction discs, ensuring consistent force transmission and easy maintenance. Perfect for agricultural, landscaping, and farming applications where PTO shaft protection is critical.
