AB2102 21 Inch Mulching Mower Blade Replacement for EGO 21" Electric Lawn Mowers, Lawn Mower Blade Compatible with EGO LM2110/LM2110-FC, LM2110SP/LM2110SP-FC, LM2120SP/LM2120SP-FC

What It Is

This is a 21-inch mulching blade replacement for EGO’s 21-inch cordless electric lawn mowers. It’s designed to cut grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck. This blade fits the following EGO models: LM2110, LM2110-FC, LM2110SP, LM2110SP-FC, LM2120SP, and LM2120SP-FC. It is an aftermarket replacement, not an OEM EGO part. Check your current blade’s center hole diameter and overall length (21 inches tip-to-tip) to ensure a match. Also verify the blade’s orientation and that the mounting hole pattern aligns with your mower’s spindle.

Key Things to Know

• Quality: Made from hardened steel, but not as thick as some OEM blades. Expect slightly less durability if you hit rocks or roots frequently.
• Installation: Easy with a socket wrench. Use a blade removal tool or a block of wood to prevent the blade from spinning. Torque the bolt to 35–40 ft-lbs.
• Common Gotcha: The blade is reversible, but the cutting edge only works in one direction. Install with the lift wings pointing upward. Double-check the arrow on the blade matches your mower’s rotation direction (counterclockwise when viewed from above).
• Performance: Cuts well on dry grass but may clog in thick, wet turf. For best results, mow at a higher deck setting and avoid cutting more than one-third of the grass height at a time.

Should You Buy It

Buy this if you own one of the listed EGO 21-inch mowers and want a budget-friendly mulching blade that performs well in normal conditions. It’s a solid alternative to OEM parts for homeowners who mow weekly and don’t need heavy-duty durability. Skip it if you regularly mow rough terrain or need a blade that handles wet grass without clogging.
