EGO POWER+ 21" High-Lift Blade for Electric Lawn Mowers LM2101/LM2100/LM2102SP/LM2100SP/LM2142SP - AB2101

What It Is

This is a high-lift blade designed to replace the standard blade on EGO 21-inch cordless electric mowers. It creates stronger airflow to improve grass clipping discharge and bagging performance, especially in thick or damp grass.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 21 inches and that the model number matches one of these: LM2101, LM2100, LM2102SP, LM2100SP, or LM2142SP. This is an OEM replacement (part AB2101) made by EGO, so it bolts directly to the stock spindle without adapters. The blade measures 21 inches tip-to-tip with a 5-point star center hole and 0.2-inch thickness. It will not fit older EGO models (e.g., LM2000 series) or any non-EGO mower. Check your owner’s manual or existing blade for the star-shaped drive pattern—if it’s a round or keyed hole, this won’t work.

Key Things to Know

• Lift vs. standard: High-lift blades pull more air, so they’re better for bagging but can reduce run time slightly on a battery mower. Expect 1-2 fewer minutes per charge in heavy grass.
• Installation is simple: One center bolt (13/16-inch or 21mm socket), no special tools needed. Torque to 35-40 ft-lbs. Always disconnect the battery and remove the safety key before flipping the mower.
• Sharpening: You can sharpen this blade 2-3 times before replacement. Balance it after sharpening to avoid vibration. Replace if bent, cracked, or if the cutting edge is worn past the hardened zone.
• Common gotcha: If your mower vibrates excessively after installing, check that the blade is centered on the star drive and the bolt is fully tightened. Also verify the blade isn’t hitting the deck sides—clearance should be at least 1/8 inch.

Should You Buy It

If you own a compatible EGO 21-inch mower and want better bagging performance—especially in thick, wet, or tall grass—this is a worthwhile upgrade over the stock blade. It’s a direct OEM fit, easy to install, and well-reviewed for improving discharge. However, if you primarily mulch or want maximum runtime, the standard low-lift blade may suit you better.
