OCPTY Electric PTO Clutch Fit for Woods: 388740; for Big Dog for Hustler: 601311, 601311K;for Hustler Super Mini Z 44 52'' Zero Turn PTO Clutch for Warner : 5218-154; for Stens: 255-642, 255-552

What It Is

The OCPTY Electric PTO Clutch engages and disengages the mower blades on zero-turn mowers. It’s a direct-fit replacement for specific Woods, Big Dog, Hustler, Warner, and Stens models—primarily used on 44" and 52" Super Mini Z decks and similar commercial/residential units.

Fitment & Compatibility

Before buying, verify these three things:

• Brand/Model: Fits Woods (388740), Big Dog/Hustler (601311, 601311K), Hustler Super Mini Z 44” & 52”, Warner (5218-154), and Stens (255-642, 255-552).
• Electrical Specs: 12V DC, 2-wire engagement. Measure your existing clutch’s voltage and wire count.
• Physical Dimensions: Shaft diameter must match your PTO shaft (typically 1” or 1-1/8”). Check bolt pattern and overall diameter (roughly 4.5–5”). If your OEM clutch has a different shaft size or offset, this won’t fit.

Cross-reference your OEM part number against the list above. If your mower uses a different Warner or Stens number, measure first.

Key Things to Know

• Quality vs. OEM: At $57.99, it’s about 1/3 the cost of a factory Warner or Stens clutch. Some users report shorter lifespan under heavy commercial use—expect 1–2 seasons on a residential mower.
• Installation: Moderate difficulty. You’ll need a puller to remove the old clutch and a torque wrench for the center bolt (usually 40–50 ft-lbs). Disconnect battery first.
• Common Gotchas: The wire harness may be slightly shorter than OEM—zip-tie any slack. Also, the air gap is preset; don’t adjust it unless you have a feeler gauge (0.010–0.015”).
• Noise/Vibration: A few users note slightly more engagement noise or vibration compared to OEM. Check that the pulley is seated flush to avoid belt wear.

Should You Buy It

Buy this if you need a budget-friendly replacement for a residential zero-turn (e.g., Hustler Super Mini Z) and are comfortable with a DIY install. Skip it if you mow commercially daily, need a long warranty, or can’t risk downtime—spend extra for a Stens or OEM Warner clutch.
