What It Is

This is an aftermarket electric PTO (power take-off) clutch that engages and disengages the mower deck blades on compatible Cub Cadet and MTD lawn tractors. It replaces OEM part numbers 917-04174, 917-04174A, 717-04174, and 717-04552A, among others.

Fitment & Compatibility

Check these before buying:

• Models: Fits Cub Cadet L1050, i1042, i1046, i1050, L1046, LTX1050, and select MTD equivalents. Verify your model’s deck size (typically 42–50 inches) – larger decks may use a different clutch.
• Connector: This version has a male pin electrical connector. Confirm your mower’s harness is female – if it’s male, you need the female-pin variant.
• OEM vs aftermarket: It’s a direct replacement for OEM numbers listed, but measure your old clutch’s shaft diameter (typically 1 inch) and bolt pattern (three or four holes) to ensure match.
• Physical dimensions: Approx. 5.5 inches outer diameter, 2.5 inches thick. Compare with your original to avoid clearance issues with the frame or belt.

Key Things to Know

• Quality: Buyers report it runs quieter and engages smoother than some OEM units, but it’s not a heavy-duty commercial part – best for residential use.
• Installation difficulty: Moderate. Requires removing the mower deck, belt, and sometimes the drive shaft. Have a puller tool for the pulley and a torque wrench (specs: 35–45 ft-lbs for mounting bolts).
• Common gotchas: The clutch may need a 1–2 hour break-in period. If it slips initially, check air gap (0.010–0.020 inches) and adjust shims. Also verify the harness connection is secure – loose pins cause intermittent engagement.
• Warranty: Typically includes a 1-year limited warranty. Keep your receipt and original packaging.

Should You Buy It

If you need a reliable, budget-friendly replacement for a Cub Cadet or MTD lawn tractor with a compatible male-pin connector, this clutch is a solid choice for residential mowing. It’s not for heavy commercial use, but for standard lawn care, it offers good value at $122.99 with strong user ratings. Just double-check your model and connector type before ordering.
