This is a replacement steel blade for 21-inch deck EGO Power+ 56V cordless mowers, designed for 3-in-1 operation (mulching, bagging, side discharge). It’s a direct aftermarket alternative for OEM blade part #AB2100.
Fitment & Compatibility
Before buying, verify your mower model is one of these: LM2100, LM2101, LM2100SP, LM2102SP, or LM2142SP. The deck must be exactly 21 inches wide. Measure your existing blade’s length (should be ~21 inches end-to-end) and center hole diameter (usually 1 inch). Confirm the blade’s offset and thickness match your original; this blade is steel but may be thinner or have a different air-lift profile than OEM. It’s not compatible with 20-inch or 22-inch decks, or with other EGO models like the LM2000 series.
Key Things to Know
- Quality concerns: With a 1.0-star average from only 3 reviews, expect potential issues with balance, sharpness, or premature wear. Some users report blades arriving dull or bent.
- Installation difficulty: Easy if you have a socket wrench (typically 9/16” or 5/8” bolt). But you must check blade balance before mounting—unbalanced blades cause vibration and damage the spindle.
- No hardware included: This is a 1-pack blade only. You’ll need to reuse your existing bolt, washer, and nut, which should be replaced every 2-3 blade changes.
- Mulching performance: May not lift grass as well as OEM due to different air-flow design; test on a small patch first.
Should You Buy It
Only buy this if you’re on a tight budget and already own one of the listed EGO models, and you’re willing to risk poor fit or short lifespan. For most users, spending a few dollars more on an OEM EGO blade (part #AB2100 or equivalent) is smarter—it will come balanced, last longer, and deliver consistent cut quality. This aftermarket blade is a gamble best avoided unless you can easily return it.
