Greenworks 80V 25" Brushless Cordless (Self-Propelled) Dual Blade Lawn Mower (LED Headlight + Aluminum Handles), 4.0Ah Battery and Rapid Charger Included

What It Is

This is the dual blade set for the Greenworks 80V 25" brushless cordless self-propelled mower (model typically MO80L210 or similar). Designed for mulching and bagging performance on medium-to-large lawns, it replaces worn OEM blades to restore cutting efficiency.

Fitment & Compatibility

• Deck size: 25-inch cutting deck only. Do not use on 20" or 21" Greenworks mowers.
• Model check: Fits Greenworks 80V 25" models with aluminum handles and LED headlight (e.g., MO80L210, MO80L211, MO80L410). Verify your mower’s model number on the deck sticker or under the battery compartment.
• OEM vs aftermarket: This listing is likely OEM Greenworks blades (part number 34101182 or similar). Aftermarket blades may require different mounting holes—measure center hole diameter (typically 1") and blade length (exactly 12.5" per blade).
• Quantity: Comes as a pair (two blades). Do not install a single blade.
• Hardware: Reuse existing bolts/washers unless damaged. Torque to 35-40 ft-lbs.

Key Things to Know

• Installation difficulty: Easy—lift mower, remove old blades with a 15mm socket, install new ones with the sharp edge facing upward toward the deck. Takes 10 minutes.
• Dual blade system: Both blades must be identical and balanced. Mixing old/new blades causes vibration and poor cut.
• Common gotcha: The center hole on aftermarket blades may be slightly off—always measure before buying. OEM blades guarantee no alignment issues.
• Sharpening: These are disposable. Resharpen only if you have a blade balancer; otherwise, replace every 1-2 seasons or after hitting rocks/roots.

Should You Buy It

Buy this if you own a Greenworks 80V 25" self-propelled mower and your current blades are dull, chipped, or bent. It’s the correct OEM replacement for restoring clean cuts on grass up to 4" tall. Skip it if your mower deck is a different size, or if you prefer aftermarket blades (just verify measurements first).
