John Deere Original Equipment Model E100 Maintenance Kit + Mulching Blades

What It Is

This is a John Deere Original Equipment (OEM) maintenance kit for the E100 series lawn tractor, bundled with mulching blades. It includes an oil filter, spark plug, fuel stabilizer, air filter, and two mulching blades designed for fine clipping recycling.

Fitment & Compatibility

• Deck size: Fits John Deere E100 tractors with a 42-inch (107 cm) cutting deck only. Verify your deck width stamped on the deck housing.
• Model range: Compatible with E100, E110, E120, E130, E140, E150, E160, E170, and E180. Not for E210 or X300 series.
• OEM vs aftermarket: This is genuine John Deere—guaranteed fit. Aftermarket blades may need different part numbers.
• Measurements: Blades are 21 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset. Check your existing blade length and hole pattern before ordering.

Key Things to Know

• Installation difficulty: Easy for DIYers—basic tools (socket wrench, torque wrench) needed. Torque blade bolts to 30–35 ft-lbs.
• Mulching vs bagging: These blades are designed for mulching (fine cuts). If you primarily bag or discharge, consider a standard lift blade kit instead.
• Kit contents: Includes one oil filter (AM125424), one spark plug (AM126070), one air filter (M806924), fuel stabilizer, and two mulching blades (M169673). Not a full tune-up—no fuel filter included.
• Common gotcha: The spark plug gap is pre-set, but double-check to 0.030 inches. Over-tightening the oil filter can cause leaks.

Should You Buy It

Buy this if you own a 42-inch John Deere E100 series and want a one-stop OEM kit for mulching with a basic tune-up. It’s a solid value for maintaining warranty and ensuring perfect fit, but skip it if you need bagging blades or own a different deck size.
