What It Is

This is an electric PTO (Power Take-Off) clutch that engages and disengages the mower blades on select Cub Cadet lawn tractors. It replaces the OEM clutch on models like the LT1042, LT1045, LT1046, LT1050, and SLT1550, and is cross-compatible with Warner 5217-32/5217-43 and XTREME X0013 units.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just the series) and deck size. This clutch fits 42-inch, 46-inch, and 50-inch decks on the listed Cub Cadet models, but not all LT-series or SLT-series tractors. Measure the clutch’s mounting bolt pattern: it should have three holes on a 3-inch bolt circle. Also confirm the shaft diameter is 5/8-inch (common for these models). If your existing clutch has different measurements or a different wiring connector, this part won’t work without modification.

Key Things to Know

• Quality vs. OEM: This is an aftermarket replacement, not a genuine Cub Cadet part. It’s generally reliable for the price, but may have slightly shorter lifespan than OEM (3-5 years vs. 5-8 years typical for OEM).
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench) and about 1-2 hours. The hardest part is accessing the clutch under the deck—expect to remove the mower deck or use a creeper.
• Common gotcha: The wiring harness plug may not match your tractor’s connector perfectly. Some users report needing to splice or replace the plug—check your existing connector type before starting.
• Torque spec: Tighten the center bolt to 30-35 ft-lbs. Overtightening can warp the clutch plate or damage the bearing.

Should You Buy It

If you need a budget-friendly replacement for a Cub Cadet LT1042 or similar model and are comfortable with basic mechanical work (including possible wiring adaptation), this clutch offers good value. Skip it if you want OEM longevity or a drop-in fit without any modification.
