Ketofa AB2100 Lawn Mower Blade - 21" Replacement for EGO Power+ 56V Models LM2101/LM2100/LM2102SP/LM2142SP/LM2100SP - 1 Pack

What It Is

The Ketofa AB2100 is a 21-inch replacement blade designed for EGO Power+ 56V cordless lawn mowers. It’s a direct aftermarket option for the OEM EGO blade, intended for homeowners needing a spare or replacement for mulching or bagging on residential lawns.

Fitment & Compatibility

This blade fits EGO 56V mowers with a 21-inch cutting deck, specifically models LM2101, LM2100, LM2102SP, LM2142SP, and LM2100SP. Before buying:

• Measure your existing blade – Confirm it’s exactly 21 inches from tip to tip and has a 6-point star center hole (common to EGO). This blade uses that star pattern, not a standard oval or round hole.
• Check your mower model number – It’s listed on the underside of the deck or in the manual. Only buy if your model is in the list above; other EGO 21-inch models (e.g., LM2130SP) may differ.
• OEM vs aftermarket – Ketofa is a third-party replacement, not EGO-branded. It should fit mechanically, but verify the blade thickness (0.15 inches typical) matches your mower’s spindle clearance.

Key Things to Know

• Installation difficulty – Easy, but you’ll need a socket wrench (usually 15mm or 5/8 inch) and a blade removal tool or wood block to lock the blade. Torque to 30-35 ft-lbs.
• Quality – A few reviews note the blade is slightly lighter than OEM, which may affect cut quality on thick grass. Sharpen before first use if it feels dull.
• Gotcha – The star hole can be tight on some spindles. If it doesn’t seat fully, don’t force it; file the hole lightly or return.
• Balance – Check blade balance after installation (hang it on a nail). An unbalanced blade causes vibration and mower wear.

Should You Buy It

Buy this if you need a budget-friendly spare for a compatible EGO 21-inch mower and don’t mind a slight drop in OEM cut quality. It’s fine for typical weekly mowing but skip it if you demand factory-grade sharpness or have heavy-duty, tall grass conditions.
