AB2101 Lawn Mower Blade for EGO 56V, High Lift Blade Fits for 21" Deck, Replaces LM2100, LM2101, LM2102-SP, LM2100-SP, LM2142-SP, 1 Pack

What It Is

This is a high-lift replacement blade for 21-inch deck EGO 56V cordless mowers. It’s designed for cutting grass with improved airflow and bagging performance compared to standard blades.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 21 inches (measure blade tip to tip). This blade fits EGO models LM2100, LM2101, LM2102-SP, LM2100-SP, and LM2142-SP. It is not OEM but is a direct replacement – no adapter or modification needed. Check that your mower uses a single blade (not dual-blade systems). Also verify the blade’s center hole diameter (common on EGO is 1-inch) and the overall length matches your original (measure from center hole to tip on each end – should be 21 inches total).

Key Things to Know

• High-lift design creates stronger suction, improving bagging and mulching but may reduce battery runtime slightly.
• Installation difficulty: Easy – requires a 15mm socket or wrench, no special tools. Torque to 35-40 ft-lbs.
• Common gotcha: Ensure the blade is oriented with the lift curve facing up toward the deck (curved edge should point up when installed). Reversing it will cause poor cutting and vibration.
• Quality: Made from heat-treated steel, but some users report it’s slightly thinner than OEM – inspect for balance before installing (use a blade balancer or nail-in-wall test).

Should You Buy It

If you own one of the listed EGO 21-inch mowers and need a reliable, high-lift blade for thicker grass or better bagging, this is a solid budget-friendly choice. Avoid if you prefer OEM-only parts or need a low-lift blade for sandy/light-duty conditions.
