21 Inch Lawn Mower Blade Replacement AB2100 AB2101, Compatible with E-GO Power+ 56V Models LM2100 LM2101 LM2100SP LM2102SP LM2114 LM2114SP LM2125SP, Black Mulching Lawn Mower Blade（2 PCS）

What It Is

This is a pair of 21-inch mulching blades designed specifically for E-GO Power+ 56V lawn mowers. They replace OEM parts AB2100 and AB2101, used for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Check these before buying:

• Deck size: Must be a 21-inch cutting deck. This blade is not for 20-inch or 22-inch decks.
• Model compatibility: Fits E-GO models LM2100, LM2101, LM2100SP, LM2102SP, LM2114, LM2114SP, and LM2125SP. Does not fit older E-GO models or other brands.
• OEM replacement: Replaces E-GO part numbers AB2100 and AB2101. If your mower uses a different blade part number (e.g., AB2102), these won’t work.
• Measurements: Blade length is 21 inches, center hole diameter is typically 1 inch, and the blade has a 5-point star-shaped drive hole. Verify your existing blade matches this shape before ordering.

Key Things to Know

• Quality: Aftermarket blades at a lower price than OEM. Many users report they cut well and last a full season with normal use.
• Installation: Straightforward – remove the old blade, install the new one with the airlift wing facing up toward the deck. Torque the bolt to 30-40 ft-lbs. Use a blade removal tool to hold the blade steady.
• Common gotcha: These are mulching blades, not bagging or side-discharge blades. They have more curved surfaces and a higher lift to recirculate clippings. If you bag frequently, you may prefer a standard blade.
• Balance: Each blade should be balanced before installation. Use a blade balancer or a nail in the wall – if one side dips, file the heavy side slightly.

Should You Buy It

If you own one of the listed E-GO 56V mowers and want an affordable mulching blade that performs on par with OEM, this is a solid choice. It’s best for users who mulch regularly and don’t need a bagging blade. Avoid if you have a different brand or model, or if you prefer OEM parts for warranty reasons.
