OCPTY Electric Lawn Mower Clutch 3813 Replacement for XTREME: X0101, for SEARS for Craftsman/for Swisher: 3813 Electric PTO Clutch

What It Is

The OCPTY 3813 is an aftermarket electric PTO (power take-off) clutch that engages and disengages the mower blades on select zero-turn and riding mowers. It replaces the OEM part on Craftsman, XTREME, Swisher, and certain Sears/Craftsman models with a 3813-style clutch.

Fitment & Compatibility

Before buying, verify:

• OEM Part Number: This replaces OEM 3813. Confirm your current clutch has “3813” stamped on it or is listed as compatible in your manual.
• Model Cross-Reference: Fits XTREME X0101 and Swisher models using the 3813 clutch. For Craftsman/Sears, check your mower’s model number (e.g., 917.xxxxx) in the product description or with the seller.
• Physical Measurements: Measure your old clutch’s shaft diameter (typically 1” or 5/8”), bolt pattern (usually 3-hole), and overall diameter (approx. 4.5”). The OCPTY 3813 matches standard 3813 dimensions, but slight variations exist—measure before ordering.
• Deck Size & Engine: Does not depend on deck size, but ensure your mower’s electrical system (12V) and wiring harness match the clutch’s two-wire connector.

Key Things to Know

• Installation Difficulty: Moderate. You’ll need basic tools (socket set, wrench) to remove the old clutch and belt. Expect 30–60 minutes. Disconnect the battery first.
• Quality: Aftermarket part with solid reviews (5.0 stars, 2 reviews). It’s not OEM, so expect a slightly different finish or wire length. Most users report it works as a direct replacement.
• Common Gotchas: The clutch may come with a different connector style. You might need to splice wires or use included adapters. Also, the belt must be routed correctly—take a photo before removal.
• Warranty: Check seller return policy; aftermarket clutches often have a 30–90 day warranty. Test immediately after install.

Should You Buy It

If you need a budget-friendly replacement for a worn 3813 clutch on a Craftsman, XTREME, or Swisher mower, this is a solid choice. It’s ideal for DIYers comfortable with basic wiring and belt work. For OEM purists or complex installs, consider a genuine Craftsman part.
