EGO Power+ 21" Replacement Mower Blade AB2100 — 3-in-1 Steel, Factory-Sharpened for LM2100/LM2101/LM2142SP

The EGO POWER+ 21" AB2100 replacement blade is a factory-sharpened steel mower blade engineered to restore precise, 3-in-1 cutting performance for compatible EGO cordless mowers.

If your EGO 20.5"/21" mower is leaving ragged cuts, uneven clippings, or reduced bagging and mulching efficiency, a fresh AB2100 blade brings the sharp edge and design it needs. This genuine EGO part is built to match the fit and function of LM2101, LM2100, LM2102SP, LM2100SP and LM2142SP models so you avoid fitment headaches and get consistent results. Ahead are the practical details buyers care most about when replacing a mower blade—how it cuts, what it fits, and how to tell when replacement is due.

How does this blade improve cutting and lawn appearance?

The AB2100 arrives factory-sharpened for immediate use, producing cleaner tears of grass than a worn blade. Clean cuts look neater and help grass recover more evenly, reducing the brown tips caused by tearing. The blade’s profile supports mulching, bagging and side discharge so you can choose the finish you want.

• Factory-sharpened steel edge for consistent slice and reduced tearing
• 3-in-1 geometry: optimized for mulching, bagging, or side discharge
• Balanced design reduces vibration and helps even cutting height

Which EGO mower models is the AB2100 compatible with?

This blade is manufactured to fit current EGO 21" deck models and their SP variants, matching the factory mounting and clearance. Compatibility ensures the blade sits correctly under the deck for safe operation and proper grass flow. Always verify your model number before ordering.

• Compatible with LM2100, LM2100SP, LM2101, LM2102SP, and LM2142SP
• Designed for EGO 20.5"/21" cutting decks that use AB2100 specification blades
• Genuine EGO part to preserve warranty alignment and performance

What installation and maintenance steps should I follow?

Replacing the AB2100 is a straightforward task if you follow safety steps: disconnect the battery, tip the mower to its service position, and remove the old blade using the correct socket size and torque. Inspect the blade bolts and replace any damaged fasteners, then torque to the mower manufacturer’s specification. Regularly check the blade for nicks and balance to extend its life.

• Always disconnect battery and follow mower manufacturer safety instructions
• Inspect mounting bolt and replace if worn; re-torque to spec after installation
• Sharpen or replace blade when nicks, warping, or reduced cut quality appear

Will this blade support mulching without extra adapters?

The AB2100 is engineered as a true 3-in-1 blade, so it will mulch effectively with compatible EGO decks as shipped. It lifts and recirculates clippings for mulching, delivers an opening for bagging, and can be used for side discharge when preferred. Performance can depend on grass length and mower speed, so adjust cutting height and mow in dry conditions for best mulching results.

• 3-in-1 blade profile built to mulch, bag, or side-discharge
• No special adapters required when used with compatible EGO decks
• Best results on dry grass and appropriate deck height settings

Who is this for? The EGO POWER+ 21" AB2100 replacement blade is for EGO owners who want a direct-fit, factory-sharpened steel blade to restore clean cutting performance and flexible 3-in-1 functionality. It’s ideal for homeowners and landscape pros using LM2100-series 21" decks who value genuine parts for fit, balance and consistent lawn appearance.
