AB2101 Lawn Mower Blade for EGO 56V, High Lift Blade Fits for 21" Deck, Replaces LM2100, LM2101, LM2102-SP, LM2100-SP, LM2142-SP, 2 Pack

What It Is

This is a high-lift mulching blade set designed to increase grass lift and airflow for a cleaner cut on EGO 56V battery mowers with a 21-inch deck. The AB2101 is ideal for homeowners seeking improved bagging performance and a finer clippings finish on standard residential lawns.

Fitment & Compatibility

Before purchasing, verify your mower deck size is exactly 21 inches (measure from blade tip to blade tip). This blade directly replaces OEM EGO part AB2101 and fits models LM2100, LM2101, LM2102-SP, LM2100-SP, and LM2142-SP. It is a two-pack, so you get a spare for balanced wear. Do not assume it fits other EGO 21-inch models—check your model number on the mower’s serial plate or manual. The blade has a 5-point star center hole (0.5-inch) and a 20-inch cutting diameter; measure your existing blade’s center hole shape and length to confirm.

Key Things to Know

• High-lift design increases suction but may cause more power draw and slightly shorter battery runtime compared to standard blades.
• Installation is straightforward—use a 15/16-inch wrench on the bolt (torque to 35-40 ft-lbs), but always disconnect the battery first.
• Balance check recommended—aftermarket blades can sometimes be slightly off; use a blade balancer before mounting to avoid vibration.
• Sharpness out of box is good but not exceptional; some users report a quick dulling on sandy soil or tough weeds.

Should You Buy It

If you own a compatible EGO 56V model listed above and want better bagging performance without switching to a dedicated bagging blade, this is a solid, affordable upgrade. However, if you have a different EGO 21-inch model (e.g., LM2130 or LM2150), double-check fitment first—and for very thick or wet grass, consider a mulching-only blade instead.
