AB2000 Lawn Mower Blade for EGO 3705369001 20 Inch LM2000, LM2001, LM2022SP, LM2020SP, LM2021

What It Is

This is a 20-inch replacement blade (model AB2000) designed for EGO cordless mowers with a 20-inch deck, specifically the LM2000, LM2001, LM2022SP, LM2020SP, and LM2021 models. It’s a standard mulching/cutting blade for residential lawn maintenance.

Fitment & Compatibility

• Deck size: Only fits 20-inch EGO mowers—do not use on 21-inch or other sizes.
• Model check: Confirmed for LM2000, LM2001, LM2022SP, LM2020SP, LM2021. Not compatible with older EGO models like LM2100 series or any gas mower.
• OEM vs aftermarket: This is an OEM EGO blade (part 3705369001), so no fitment issues with center hole or bolt pattern. Aftermarket blades may vary—measure center hole diameter (typically 1-inch) and bolt pattern before buying non-OEM.
• Measure before buying: Verify your current blade length is exactly 20 inches from tip to tip, and the mounting hole matches. EGO uses a single bolt with a lock washer—no adapter needed.

Key Things to Know

• Quality: 3.8/5 rating suggests decent but not premium steel. Some users report dulling faster than OEM original blades (likely due to batch variation). Expect ~10-15 mows before sharpening on average lawns.
• Installation: Easy DIY—remove one bolt with a 15mm socket, lift old blade, torque new one to 35-40 ft-lbs. No special tools needed. Always disconnect battery first.
• Common gotcha: The blade is directional—the curved side must face up toward the deck. Installing upside down will cause poor cutting and vibration.
• Balance: Out-of-box balance is usually fine, but check with a blade balancer if you notice vibration after install. Slight imbalance can damage the spindle over time.

Should You Buy It

Buy this if you own one of the listed EGO 20-inch mowers and want a direct OEM replacement without measuring or adapter worries. It’s a solid choice for routine blade swaps, though you may want to sharpen it more often than pricier aftermarket options. Skip if you need a heavy-duty blade for thick, wet grass—consider a high-lift or mulching upgrade instead.
