What It Is

The New Outdoor Power Xtreme Equipment X0013 is an aftermarket PTO (Power Take-Off) clutch that engages and disengages the mower deck blades on select Cub Cadet lawn tractors. It’s designed to replace a failed OEM clutch on models like the L1046, L1050, LT1042, LT1045, LT1046, LT1050, SLT1550, and SLT1554.

Fitment & Compatibility

Before buying, confirm your Cub Cadet model number and deck size (typically 42" or 50"). This clutch replaces OEM part numbers 717-04163, 717-04163A, 917-04163, and 917-04163A. Measure your existing clutch’s shaft diameter (usually 1” or 7/8”) and bolt pattern (three or four holes) to match. It fits tractors with a 12-volt electrical system and a single-wire engagement design. Double-check that your mower uses a 3-pin connector; some older models may differ.

Key Things to Know

• Quality vs. OEM: Aftermarket, but rated 4.6/5 from 119 reviews. Users report it’s a solid alternative at half the OEM price, though some note slightly less durable bearings over time.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and a multimeter to test electrical continuity. Expect 1–2 hours; no special skills required, but careful alignment is critical.
• Common gotchas: The clutch may arrive with a protective coating on the friction plate—wipe it clean with brake cleaner before install. Also, check your battery voltage (12.6V+) and wiring harness for corrosion; low voltage or bad connections cause premature failure.
• Deck clearance: Ensure the clutch doesn’t hit the deck belt or pulley when engaged. Measure the air gap (usually 0.010–0.020”) and adjust if needed.

Should You Buy It

If you’re on a budget and need a reliable replacement for a failed OEM clutch on a compatible Cub Cadet lawn tractor, this is a strong pick. It works well for residential use with moderate mowing hours. For heavy commercial duty or if you want the longest lifespan, consider spending more on an OEM unit.
