Greenworks 20 in. Walk Behind Mower Blade - 1 Each

What It Is

This is an OEM replacement blade for Greenworks 20-inch walk-behind mowers. Designed for mulching and bagging, it’s a single straight blade with a medium lift profile for standard residential cutting.

Fitment & Compatibility

• Deck size: Only fits 20-inch cutting decks. Do not use on 21-inch or other sizes.
• Model fit: Compatible with Greenworks 20-inch models, including 25022, 25142, 25262, and 26062. Check your mower’s model number (under the seat or on the deck sticker) to confirm.
• OEM vs aftermarket: This is a genuine Greenworks part (OEM), not a universal or aftermarket blade. It ensures exact fit and balance.
• Measurements: Blade length is 20 inches (measure from tip to tip, straight across). Center hole is 1 inch round. Do not assume other brands’ 20-inch blades will match—Greenworks uses a specific offset and hole pattern.

Key Things to Know

• Quality: High-carbon steel with a coated finish for rust resistance. Sharp out of the box but dulls faster than premium aftermarket blades in abrasive soil.
• Installation difficulty: Easy (10 minutes) with a socket wrench. Torque blade bolt to 35-40 ft-lbs—overtightening can strip the adapter.
• Common gotchas: This is a single blade, not a set. For twin-blade decks (some newer 20-inch models), you’ll need two. Also, check blade adapter for wear before installing—a worn adapter can cause wobble even with a new blade.
• Balance: Pre-balanced from factory, but still check with a blade balancer after installation to avoid vibration.

Should You Buy It

Buy this if you need a direct OEM replacement for your Greenworks 20-inch walk-behind and want guaranteed fit without measuring or modifying. It’s right for owners of the listed models who value simplicity over cost savings. Skip it if you want a longer-lasting, premium aftermarket blade (e.g., Oregon or Gator) for heavy-duty mulching—those offer better durability at a similar price.
