What It Is

The OCPTY Electric PTO Clutch 717-04376 engages and disengages the mower blades on lawn tractors and zero-turn mowers. It’s designed for Bolens, Cub Cadet, Huskee, MTD, Sears Craftsman, Troy Bilt, and White Outdoor models that use a 12V electric PTO system.

Fitment & Compatibility

Before buying, confirm your machine uses OEM part numbers 717-04376, 717-04376A, 917-04376, or 917-04376A. This is a direct aftermarket replacement for those. Measure the clutch’s shaft diameter (typically 1 inch) and bolt pattern (three holes on a 3.25-inch circle). Check your deck size—this clutch fits most 42- to 54-inch decks on the listed brands, but verify your specific model number via the manufacturer’s parts diagram. It does not fit all Cub Cadet or MTD models; cross-reference your tractor’s model and serial number.

Key Things to Know

• Quality: Rated 4.4/5 from 272 reviews. Users report it’s a solid aftermarket alternative to OEM, but some note occasional bearing noise after heavy use. Inspect for smooth rotation before install.
• Installation: Moderate difficulty. You’ll need basic tools (socket set, torque wrench) and must disconnect the battery. The clutch bolts to the engine crankshaft; torque to spec (typically 35-45 ft-lbs). No special wiring harness is included—use your existing connector.
• Common Gotcha: The clutch may come with a spacer or washer missing. Check your old clutch for any shims and reuse them. Also, ensure the air gap is 0.010–0.015 inches after install; adjust with the included feeler gauge if needed.
• Warranty: Most sellers offer a 1-year warranty. Keep your receipt and test the clutch immediately—defective units are rare but possible.

Should You Buy It

If your Bolens, Cub Cadet, or MTD tractor needs a PTO clutch and you want a reliable, cost-effective alternative to OEM (which often costs $120+), this is a solid buy. It’s best for DIY mechanics comfortable with basic engine work. Avoid if you need a perfect OEM match or have a non-standard deck size—stick with a dealer for those.
