OCPTY Electric PTO Clutch 917-04622 fit for Bolens for Cub Cadet for Huskee for Sears Craftsman for Troy Bilt for White Outdoor: 717-04183, 717-04622, 917-04183, 917-04622, GT1A-MT09

What It Is

This is an aftermarket electric PTO (power take-off) clutch that engages and disengages the mower blade(s) on select lawn tractors from Bolens, Cub Cadet, Huskee, Sears Craftsman, Troy-Bilt, and White Outdoor. It replaces OEM part numbers 717-04183, 717-04622, 917-04183, and 917-04622.

Fitment & Compatibility

Before buying, confirm your mower’s model number (not just brand) and deck size—this clutch fits most 42-inch to 54-inch cutting decks on compatible tractors. Measure the shaft diameter (typically 1 inch) and bolt hole spacing (common 3-inch center-to-center). Compare physical dimensions with your old clutch: overall diameter (approx. 4.5 inches) and thickness (about 2 inches). Cross-reference your OEM part number against the list above—this is a direct replacement for those, not a universal fit. Check if your mower uses a 2-pin or 3-pin electrical connector; this clutch comes with a standard 2-pin flat connector.

Key Things to Know

• Quality: At 4.2 stars from 75 reviews, it’s a solid budget alternative to OEM ($150+), but some users report shorter lifespan (1-2 seasons vs. 3-4 for OEM).
• Installation: Moderate difficulty—requires removing the mower deck, disconnecting the belt, and unbolting the old clutch. You’ll need a puller tool (not included) to separate the clutch from the crankshaft.
• Common Gotcha: The air gap between the clutch rotor and armature must be set to 0.010–0.015 inches after installation; skipping this can cause slippage or failure.
• Noise: A few reviews note it runs slightly louder than OEM—normal for aftermarket, but check if noise is a concern.

Should You Buy It

If you’re on a budget and need a functional replacement for a compatible model, this is a decent value—especially if you’re handy with basic tools and can handle the air gap adjustment. But if you want maximum durability or have a high-use commercial mower, spend the extra $50–80 on an OEM Cub Cadet clutch.
