What It Is

This is an electric PTO (power take-off) clutch that engages and disengages the mower blades. It replaces OEM part numbers 179334, 400008, 414336, 471717P, 532179334, 532400008, 532414336, and fits many Husqvarna, Sears, and Craftsman lawn tractors with 42–54 inch decks.

Fitment & Compatibility

• Cross-reference your OEM part number – The OCPTY clutch matches 179334, 400008, 414336, 471717P, and others. Verify your original part number matches one listed.
• Measure your existing clutch – This unit has a 1-inch bore, 3-bolt pattern (bolt circle approx. 3.25 inches), and overall diameter of about 4.5 inches. Confirm these dimensions match your unit.
• Check your tractor model – Fits many Husqvarna GTH, YTH, and LTH series, plus Craftsman LT1000, LT2000, and DYT4000. Not universal – search your model number online with “PTO clutch 15772” to verify.
• Aftermarket replacement – This is not OEM; it’s a compatible aftermarket part. Works fine for most, but quality control can vary.

Key Things to Know

• Easy to install for a DIYer – Usually requires removing the deck, unplugging the wiring harness, and unbolting the old clutch. No special tools beyond a socket set and possibly a puller.
• Watch for air gap – After mounting, check the clutch’s air gap (typically 0.012–0.025 inches). If too tight or loose, the clutch may slip or fail to engage.
• Potential noise – Some users report a slight whine or rattle on engagement. This is common with aftermarket clutches and often not a problem, but if it’s loud, double-check mounting and air gap.
• Return policy matters – If the clutch fails within the first few uses, ensure the seller offers a replacement or refund. Some aftermarket clutches have a higher early failure rate.

Should You Buy It

This clutch is a solid budget option for DIYers replacing a known OEM part on a Husqvarna, Craftsman, or Sears tractor. If you’re comfortable with basic mechanical work and want to save money over a $150–200 OEM unit, it’s worth it. For commercial use or if you need guaranteed long-term reliability, stick with an OEM replacement.
