AB2000 Mower Blade 21 Inch Compatible with EGO Power+ 56V LM2100 LM2101 LM2100SP LM2102SP LM2142SP 21" Deck, Mulching Blade Replace for AB2101, 1 Pack

What It Is

This is a 21-inch mulching blade designed as a replacement for EGO Power+ 56V cordless mowers with a 21-inch deck. It’s intended for mulching grass clippings into fine particles to return nutrients to your lawn, not for bagging or side-discharge.

Fitment & Compatibility

• Deck size: Must be exactly 21 inches. Measure your blade from tip to tip—this blade is 21 inches long.
• Model compatibility: Fits EGO models LM2100, LM2101, LM2100SP, LM2102SP, and LM2142SP. It replaces OEM part AB2101.
• Center hole: 7-point star shape (common on EGO blades). Verify your spindle matches before buying.
• Aftermarket note: This is not an OEM EGO blade. It’s a compatible replacement. Check blade thickness (usually 0.15–0.17 inches) and ensure it matches your mower’s spindle nut torque spec (typically 35–45 ft-lbs).
• What to check: Remove your current blade and compare the center hole shape, overall length, and thickness. If your mower uses a different blade design (e.g., a 5-point star), this won’t fit.

Key Things to Know

• Mulching only: This blade has a curved, serrated design optimized for mulching. It will not work well for bagging or side-discharge—expect clumping if used for those.
• Installation: Easy for DIYers. You’ll need a wrench or socket (typically 15/16” or 13/16”) and a blade removal tool or block of wood to lock the blade. Torque to 35–45 ft-lbs.
• Balance: New blades are usually balanced, but it’s worth checking with a blade balancer. An unbalanced blade causes vibration and poor cut quality.
• Wear: Replace every 25–50 hours of use or when the blade is nicked or dull. Sharpen twice between replacements if needed.

Should You Buy It

If you own one of the listed EGO 21-inch mowers and primarily mulch, this is a solid, affordable replacement. It’s not OEM, but it’s well-rated and cheaper than the genuine EGO AB2101. Skip it if you bag or side-discharge—get a dedicated blade for those tasks.
