What It Is

An electric PTO (power take-off) clutch engages and disengages the mower blades on lawn tractors. This aftermarket replacement fits multiple John Deere and Scotts models with 42-54 inch decks, including the D100, L100, and LA series tractors.

Fitment & Compatibility

Double-check these before buying:

• Models: Fits John Deere D140, D150, D160, D170, L120, L130, G110, LA130, LA140, LA145, and Scotts L2048, L2548. Not all D/LA/L series are guaranteed—verify your deck size and year.
• OEM cross-references: Compatible with GY20108, GY20652, GY20878, GY21340, and aftermarket numbers 5219-20, 5219-73.
• Physical check: Measure your old clutch’s diameter, shaft hole size (typically 1-inch), and bolt pattern. These vary by engine and deck. If your OEM number isn’t listed, pull the clutch and measure.
• Wiring: Expect a two-wire connector (usually 12V). Confirm your tractor’s harness matches—some models use a different plug style.

Key Things to Know

• Quality concerns: Only 1 review at 3.0 stars—this is a low-volume, unbranded aftermarket part. Expect shorter lifespan than OEM (Deere-branded) clutches.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, puller), and the clutch must be shimmed correctly to the engine crankshaft. A service manual helps.
• Common gotchas: Air gap (0.010-0.015 inches) must be set after installation. Too tight or too loose and the clutch won’t engage or will burn out. Also, check your battery and charging system—low voltage kills these clutches fast.
• Return policy: Given the low rating, confirm the seller’s return window and if they cover defects. Many cheap clutches fail within a season.

Should You Buy It

This is a budget option for experienced DIYers with a compatible John Deere or Scotts tractor who need a quick, low-cost fix and are comfortable with measurement and shimming. If you want reliability, minimal hassle, or a warranty, spend more on an OEM clutch—especially for heavy-use mowing.
