AB2101D Lawn Mower Blade - 21 Inch Mulching Lawn Mower Blade Kit Compatible with EGO Lawn Mowers LM2130 LM2130SP LM2133 LM2135SP LM2150SP LM2156SP

What It Is

This AB2101D blade kit includes two 21-inch mulching blades designed specifically for EGO battery-powered lawn mowers. It replaces the factory blades on select 21-inch deck models to maintain fine grass clipping mulching performance.

Fitment & Compatibility

Before buying, confirm your mower model matches one of these EGO units: LM2130, LM2130SP, LM2133, LM2135SP, LM2150SP, or LM2156SP. Measure your existing blade length (must be 21 inches from tip to tip) and check the center hole diameter (typically 1 inch) and the drive pin/oval hole pattern—EGO blades often use a two-hole or asymmetrical design. This is an aftermarket replacement, not OEM EGO. Verify that the blade thickness and offset match your original blade to avoid clearance issues with the deck or blade adapter.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 35-45 ft-lbs), and thread locker on the bolt. Always disconnect the battery before flipping the mower.
• Mulching vs. bagging: These blades have a curved, high-lift design for fine mulching. They work for bagging too, but may not produce as clean a cut as dedicated bagging blades.
• Quality concern: With only 13 reviews at 4.3 stars, long-term durability is unproven. Some users report the coating wears off faster than OEM blades.
• Balance check: After sharpening or replacing, always balance the blades (use a blade balancer) to prevent vibration and mower damage.

Should You Buy It

Buy this kit if you own one of the listed EGO models and need a direct-fit, cost-effective replacement for worn mulching blades. It’s a good option for routine maintenance when OEM blades are priced higher or out of stock. Avoid if you want guaranteed OEM longevity or plan to use the mower primarily for bagging—dedicated bagging blades may perform better.
