Lawn Mower Blade 21 inch Compatible with EGO, Replacement Mulching Blade AB2101D for Mowers LM2133/LM2130/LM2135SP/LM2130SP/LM2156SP/LM2150SP (Green)

What It Is

This is a 21-inch mulching blade designed as a direct replacement for EGO lawn mowers, specifically for models LM2133, LM2130, LM2135SP, LM2130SP, LM2156SP, and LM2150SP. It shreds grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, verify your mower deck size is exactly 21 inches—measure from cutting edge to cutting edge if unsure. This blade is an aftermarket replacement for the OEM EGO part AB2101D. It fits only the listed EGO models; it will not work on other brands or different deck sizes. Check the blade’s center hole diameter (typically 5/8 inch on EGO) and overall length (21 inches) against your current blade. Remove one bolt to inspect the old blade’s measurements if in doubt.

Key Things to Know

• Installation is straightforward—requires a 15/16-inch socket or wrench to remove the single bolt. No special tools needed.
• Mulching performance is strong—curved wingtips and sharpened edges produce fine clippings, reducing bagging frequency.
• Balance check recommended—aftermarket blades can sometimes be slightly off-balance. Use a blade balancer before installing to avoid vibration.
• Sharpness out of box—reviews note the blade arrives sharp; handle with gloves to avoid cuts.

Should You Buy It

If you own one of the listed EGO 21-inch mowers and want a cost-effective mulching upgrade without paying OEM prices, this blade delivers solid performance and easy installation. Skip it if you need a standard bagging or high-lift blade, or if your mower model isn’t explicitly listed.
