AB2100 Lawn Mower Blade Replacement for 21'' Deck Compatible with E GO Power+ 56V Models LM2100 LM2101 LM2100SP LM2102SP LM2142SP, 3-in-1 Mulching Bagging Side Discharge Steel Blade, 2 Pack

What It Is

This is a 2-pack of 21-inch steel replacement blades designed for E GO Power+ 56V mowers with a 21’’ cutting deck. They support 3-in-1 operation (mulching, bagging, side discharge) and are built for electric mower torque and battery runtime.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Only fits 21-inch decks. Measure your deck width to confirm.
• Model list: Verified for E GO LM2100, LM2101, LM2100SP, LM2102SP, LM2142SP. Not compatible with other brands or E GO models with different deck sizes.
• OEM vs aftermarket: This is an aftermarket blade, not E GO factory. It’s a direct fit replacement—no adapters needed. The center hole and mounting pattern match the OEM blade exactly.
• Measurements: Blade length is 21 inches, with a 5-point star center hole (common on E GO 56V models). Thickness is standard for electric mower blades.

Key Things to Know

• Installation difficulty: Easy. Lift the mower, remove the center bolt, swap blades, and retorque to 35-45 ft-lbs. No special tools required.
• Quality: Made from heat-treated steel. Expect 1-2 seasons of normal residential use before dulling. Sharper out of the box than some OEM blades.
• Balance: Check balance before installing—some users report minor imbalance. Use a blade balancer or spin test on a nail.
• Common gotcha: These are reversible blades (two cutting edges per blade). Flip them once to double life, but don’t run them upside down—the lift wing orientation matters for bagging performance.
• Noise: Slightly louder than OEM blades due to the aggressive lift design. Noticeable but not excessive.

Should You Buy It

Buy these if you own one of the listed E GO 21-inch models and want a cost-effective 2-pack that works well for mulching and bagging. They’re a solid alternative to OEM blades if you’re comfortable with a quick balance check and don’t mind a minor noise increase. Skip them if you need a perfect OEM fit or have a different brand/model.
