What It Is

This is a replacement electric PTO (power take-off) clutch for select John Deere and Scotts lawn tractors. It engages the mower deck blades when you flip the PTO switch, and is a direct aftermarket alternative to the OEM part.

Fitment & Compatibility

• Check your model number: Fits John Deere D140, D150, D155, D160, D170, E140, E150, E160, E170, E180, G110, LA130, LA140, LA145, LA165, LA175, 145, 155C, 190C, X135R, X140, X165, and Scotts L2048.
• OEM cross-references: Replaces John Deere GY20108 and 5219-20.
• Measure your old clutch: This unit has a 1-inch bore, 3-pin mounting pattern, and 4.5-inch diameter. Verify these match before ordering.
• Deck size not a factor: This clutch works regardless of deck width, as long as your tractor model is listed.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and a multimeter to test continuity. The job takes about 1–2 hours.
• Quality vs OEM: Most users report it’s comparable to OEM for the price. A few note slightly louder operation or shorter lifespan under heavy use.
• Common gotcha: The mounting bolts can be tight. Use penetrating oil if they’re rusted. Also, check the air gap (0.010–0.015 in) after install—too tight or too loose can cause slipping or failure.
• Wiring: Connector may not match exactly on some models. You might need to splice or use included adapters. Have butt connectors and heat shrink ready.

Should You Buy It

If your John Deere or Scotts tractor’s PTO clutch has failed and you want a budget-friendly replacement that fits multiple models, this is a solid choice. It’s best for DIY owners comfortable with moderate mechanical work. Avoid if you need OEM exactness or run a commercial mowing operation—those users may prefer the original part for longevity.
