BeadChica Lawn Mower Blade 21 inch Compatible with EGO LM2102SP/LM2100SP/ LM2101/LM2100//LM2142SP, AB2100 Mower Blade Replacement Parts

What It Is

This is a 21-inch replacement blade for select EGO battery-powered lawn mowers, designed for mulching and bagging on residential turf. It’s a direct aftermarket alternative to the OEM EGO blade for models with a 21-inch cutting deck.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 21 inches (measure from blade tip to tip). This blade fits EGO models: LM2102SP, LM2100SP, LM2101, LM2100, LM2142SP, and the AB2100 power head. It does not fit older EGO 20-inch or 56V models with different bolt patterns. The center hole is 1-inch diameter with a star-shaped drive pattern—verify your mower uses the same. This is an aftermarket part, not OEM; it should match the original blade length, thickness, and mounting geometry. If your mower has a different blade retention system (e.g., single bolt vs. adapter plate), it won’t work.

Key Things to Know

• Quality: Made from heat-treated steel, similar to OEM. 5.0 rating from 12 reviews suggests good consistency, but inspect for burrs or uneven edges before install.
• Installation difficulty: Easy—requires a wrench or socket to remove the center bolt. No special tools needed, but always disconnect the battery first.
• Common gotchas: The star drive pattern must align perfectly with your mower’s adapter; if it’s slightly off, the blade won’t seat flat. Also, check that the blade is balanced after installation—unbalanced blades cause vibration and poor cut.
• Performance: Designed for mulching and bagging; not optimized for side discharge. Expect similar cut quality to OEM if installed correctly.

Should You Buy It

Buy this if you own one of the listed EGO 21-inch mowers and want a budget-friendly replacement that matches OEM specs. It’s a solid choice for routine blade swaps, especially if you’re comfortable with basic DIY installation. Skip it if you need a high-lift blade for thick, wet grass or prefer OEM parts for warranty reasons.
