AB2102 21-Inch Mulching Blade Replacement for EGO Power+ 21" Electric Lawn Mowers 56V Models, Manganese Steel Mower Blade Compatible with LM2110/LM2120SP/LM2110SP

What It Is

The AB2102 is a 21-inch mulching blade replacement designed specifically for EGO Power+ 21" 56V electric lawn mowers. It’s built for fine grass clipping mulching, not bagging or side-discharge—ideal for leaving nutrient-rich clippings on your lawn.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting deck EGO mowers. Do not use on 20" or 22" decks.
• Model compatibility: Confirmed for LM2110, LM2120SP, and LM2110SP. Also fits most 21" EGO 56V models (e.g., LM2100, LM2101, LM2102SP). Check your mower’s model number on the underside of the deck or near the battery compartment.
• OEM vs aftermarket: This is an OEM replacement (EGO brand), so fit and balance are guaranteed. Aftermarket blades may require balancing or have slightly different hole patterns.
• Measurements: Center hole is 7/8" diameter, blade length is 21", thickness ~0.15". Verify your existing blade matches these specs.
• What to check before buying: Remove one blade and compare the hole pattern, length, and thickness. Also ensure your mower uses two blades (this is a single blade—some models take two).

Key Things to Know

• Installation difficulty: Easy—requires a 9/16" socket or wrench. No special tools needed, but a torque wrench is recommended (tighten to 35-45 ft-lbs).
• Mulching only: This blade has a curved, high-lift design for mulching. It will not work well for bagging—clippings may clump. If you need bagging, use EGO’s standard or high-lift bagging blade.
• Durability: Made from manganese steel—holds an edge longer than standard carbon steel but is harder to sharpen. Expect 1-2 seasons of normal use before replacement.
• Gotcha: Always replace blades in pairs (if your mower uses two). Installing one old and one new will cause vibration and uneven cut. Also, torque the bolt to spec—overtightening can strip the adapter.

Should You Buy It

Yes, if you own an EGO 21" 56V mower and want a drop-in, OEM-quality mulching blade. The $27.99 price is fair for OEM reliability, and the 5.0 rating reflects consistent fit and performance. Avoid if you need a bagging blade or have a non-EGO mower.
