Mower Blade 21-Inch Replacement for EGO AB2102 Power+ 21" Electric Lawn Mower Models LM2110 LM2110SP LM2120SP, Circle Center Hole 1-Pack

What It Is

This is a 21-inch replacement blade for EGO Power+ 21” electric mowers, designed to cut grass efficiently on residential lawns. It fits models LM2110, LM2110SP, and LM2120SP—not the AB2102 trimmer.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 21 inches (measure your blade length; 20.5–21.5” won’t fit).
• Model match: Only for EGO LM2110, LM2110SP, and LM2120SP mowers. Does not fit older EGO 20” models or any gas mowers.
• Mounting hole: Center hole is circular, 1-inch diameter. Check your original blade—if it has a star or keyhole pattern, this won’t work.
• OEM vs aftermarket: This is an aftermarket blade, not EGO factory. Quality is generally fine, but tolerances may vary slightly.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade stop tool (or wood block). Torque to 35-40 ft-lbs.
• Balance: Aftermarket blades sometimes need balancing. Use a blade balancer; if one side dips, file the heavy side slightly.
• Sharpness: Arrives sharp but may need a quick hone if edges feel dull. Re-sharpen every 10-15 hours of use.
• Gotcha: This is a 1-pack. Most mowers use one blade, but double-check your model—some EGO 21” mowers use a stacked blade system (not this one).

Should You Buy It

Buy this if you own an EGO LM2110, LM2110SP, or LM2120SP and need a budget-friendly replacement that works. Skip it if you want OEM exactness or a 2-pack—EGO factory blades cost more but guarantee fit. For most homeowners, this is a solid, functional pick.
