AB2100 Lawn Mower Blade Replacement for 21'' Deck Compatible with E GO Power+ 56V Models LM2100 LM2101 LM2100SP LM2102SP LM2142SP, 3-in-1 Mulching Bagging Side Discharge Steel Blade, 1 Pack

What It Is

This is a 21-inch steel replacement blade designed for select E GO Power+ 56V cordless mowers. It’s a 3-in-1 blade that handles mulching, bagging, and side discharge, making it suitable for routine cutting on residential lawns.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be a 21″ cutting deck. Measure your deck’s cutting path if unsure.
• Model list: Fits E GO Power+ models LM2100, LM2101, LM2100SP, LM2102SP, and LM2142SP. It does not fit older or non-56V E GO models (e.g., LM2000 series).
• Blade dimensions: Center hole is 1″ diameter, blade length is 21″ (end to end). Check your current blade’s hole size and length—this is an aftermarket part, not OEM, so if your original has a different hole shape or offset, it may not align properly. Verify the blade’s thickness (approx. 0.1″) matches your mower’s spindle clearance.

Key Things to Know

• Installation is straightforward if you have a socket wrench and a blade removal tool (or a block of wood to jam the blade). No special skills required, but always disconnect the battery first.
• Balance matters: Aftermarket blades can sometimes be slightly off-balance. Spin the blade on a balancer or screwdriver before mounting to avoid vibration.
• Sharpenable: Steel construction allows resharpening, but the blade is relatively thin—expect 2-3 sharpenings before replacement. Hard use (dense grass, rocks) may dull it faster.
• No adapter included: If your mower uses a star-shaped or multi-hole mounting pattern, this blade won’t fit. It’s strictly a standard 1″ round hole.

Should You Buy It

If you own one of the listed E GO 56V models and want a budget-friendly 3-in-1 replacement, this blade works well for typical lawn care. It’s a good value for the price, but if you need exact OEM fitment or plan to cut heavy, thick grass frequently, consider spending more on a thicker OEM blade. For most homeowners replacing a dull or damaged blade, it’s a solid, easy swap.
