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

What It Is

This is a 2-pack of 21-inch high-lift replacement blades designed for EGO 56V cordless mowers. High-lift blades create stronger upward airflow, improving grass clipping discharge and bagging performance, especially in thick or wet grass.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 21-inch EGO mower decks.
• Model compatibility: Works with LM2100, LM2101, LM2102-SP, LM2100-SP, and LM2142-SP. Do not use on older EGO models (e.g., LM2000 series) without verifying.
• OEM vs aftermarket: This is an OEM EGO part (AB2101), so no adapter or modification needed.
• Measurements: Blade length is exactly 21 inches; center hole diameter is 3/4-inch (standard for EGO 21-inch decks). Confirm your current blade matches these specs.

Key Things to Know

• Installation difficulty: Easy – requires a socket wrench (usually 15mm or 5/8-inch) and a block of wood to lock the blade. No special tools needed.
• Torque spec: Tighten the center bolt to 35-40 ft-lbs. Overtightening can strip the aluminum deck adapter.
• Common gotcha: High-lift blades increase battery drain slightly compared to standard/mulching blades. Expect 5-10% less runtime on a full charge.
• Quality note: Some users report blades arriving with minor edge burrs – a quick file pass solves this. Check balance before installing if you notice vibration.

Should You Buy It

If you primarily bag grass or discharge clippings on a 21-inch EGO mower (models listed above), this is a solid, direct-fit upgrade. For mulching, stick with the OEM mulching blade set. The 3.8 rating reflects minor QC issues, but for $29.99 for two blades (half the price of buying individually), it’s good value for bagging performance.
