Key Features

• Specification: Built to accept a 1' crankshaft with a 6' pulley and CCW rotation, matching original equipment dimensions for proper alignment.
• Simple installation: One-piece design arrives pre-set so most users can replace the clutch quickly with minimal tools or adjustment.
• Compact unit and e-coating: The integrated clutch and brake occupy little space and the e-coated parts resist corrosion in outdoor conditions.

Who It's For

The SCITOO PTO Clutch is aimed at homeowners and small property owners who need a like-for-like replacement for CUB CADET LT-series machines or compatible SEARS and MTD Columbia models. It is particularly useful for DIYers who value quick, no-adjustment swaps and expect original-equipment fit and function.
