What It Is

The ACEBRI PTO clutch engages and disengages the mower blades on select John Deere and Scotts lawn tractors. It replaces worn-out OEM clutches that fail to spin up or slip under load, restoring blade operation.

Fitment & Compatibility

Before buying, verify your tractor’s model and deck size. This clutch fits John Deere/Scotts models L120, L30, LA130, LA140, D140, D150, D160, and D170. It also replaces OEM part numbers GY20878 and GY20108, and Warner numbers 5219-20, 5219-73, 5219-72, and 5219-114.

Check these before purchase:

  • Deck size: Works with 42", 48", and 54" decks on listed models.
  • Shaft diameter: Must be 1" and have a 3/16" keyway (measure your old clutch shaft).
  • Wiring: Typically two-wire (ground and power); confirm your tractor’s connector matches.
  • Mounting holes: Three-hole pattern on 4.5" bolt circle (measure center-to-center on your old clutch).

If your model isn’t listed, measure the clutch’s outer diameter (4.5") and stack height (2.25") to compare.

Key Things to Know

  • Quality: ACEBRI is an aftermarket brand. Most users report it matches OEM performance, but expect slightly less durable bearings than a genuine John Deere part.
  • Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and a feeler gauge to set the air gap (0.010–0.020"). Budget 1–2 hours.
  • Common gotcha: The clutch may arrive with a thick protective coating—clean the friction surfaces with brake cleaner before installing to prevent slipping.
  • Wiring note: Some tractors use a different connector; you may need to splice or swap the pigtail. Check your old clutch’s plug shape.

Should You Buy It

Yes, if you need a budget-friendly replacement for a worn PTO clutch on a listed John Deere/Scotts model and are comfortable with basic mechanical work. It’s a solid value for DIYers, but if you want maximum longevity or have a commercial-use mower, consider spending more on an OEM clutch.
