AB2101 Lawn Mower High Lift Blade for EGO 56V 21-Inch Lawn Mower Models LM2100, LM2101, LM2102-SP, LM2100-SP, LM2142-SP, 1 Pack 21in Mower Blade

What It Is

This is a high-lift replacement blade for EGO 56V 21-inch cordless lawn mowers. It’s designed to increase airflow under the deck for better grass lifting, bagging performance, and a cleaner cut in tall or damp grass.

Fitment & Compatibility

• Deck size: Only for 21-inch cutting decks. Measure your existing blade length (end to end) – it must be exactly 21 inches.
• Model check: Fits EGO models LM2100, LM2101, LM2102-SP, LM2100-SP, and LM2142-SP. Verify your model number on the mower’s underside or manual.
• OEM vs aftermarket: This is an OEM EGO blade (part AB2101), so no fitment issues with the spindle, center hole, or blade washer design.
• Measurements: Center hole is 1-inch diameter with a star-shaped drive pattern. Blade thickness is about 0.125 inches. Confirm these match your old blade.
• What to check before buying: Remove your current blade and compare the center hole shape and overall length. If your mower uses a different blade pattern (e.g., mulching blade), this high-lift blade won’t interchange without swapping the entire blade set.

Key Things to Know

• Installation difficulty: Easy – one bolt per blade. Use a socket wrench or blade removal tool. Torque to 35–40 ft-lbs. No special adapters needed.
• Common gotcha: High-lift blades increase motor load. In very thick or wet grass, you may notice reduced runtime or the mower struggling. Use full battery charge and avoid overloading.
• Quality: OEM EGO steel is durable but can dull faster if you hit rocks or roots. Sharpen every 10–15 hours of use for best performance.
• Single pack: This is one blade, not a set. If your mower uses two blades (some EGO models do not – check your deck), you’ll need to buy two.

Should You Buy It

Buy this if you primarily bag clippings or cut tall/damp grass and want maximum lift and suction. Skip it if you mostly mulch or side-discharge – a standard or mulching blade will give better results and longer battery life.
