25022 Lawn Mower Blade for 20 Inch / 21 Inch Mower Deck Compatible with Green-Works 25222 33313250, 1 Pack

What It Is

The 25022 is a replacement lawn mower blade designed for 20-inch and 21-inch push mower decks, compatible with Green-Works models 25222 and 33313250. It’s a standard, medium-lift blade for general residential grass cutting.

Fitment & Compatibility

Before buying, check three things:

• Deck size: Fits 20" and 21" cutting decks only. Measure your deck width to confirm.
• OEM cross-reference: Directly replaces Green-Works part numbers 25222 and 33313250. Also fits many other brands using the same blade pattern—verify against your original blade.
• Measurements: Center hole diameter is typically 1" (check yours). Blade length should match your current blade exactly (usually 20" or 21"). Thickness and offset must match to avoid vibration or poor cut.

If your mower uses a different mounting pattern (oval hole, star, or multi-point), this blade won’t work.

Key Things to Know

• Installation difficulty: Easy. Requires a socket or wrench to remove the center bolt. Always disconnect the spark plug first.
• Sharpness: Comes sharp enough for light use but benefits from a quick touch-up with a file before first cut.
• Balance: Check blade balance after installation—unbalanced blades cause vibration and damage the spindle.
• Lift: Medium-lift design works well for dry, normal grass. Not ideal for thick, wet grass or mulching heavy loads.

Should You Buy It

Buy this if you own a Green-Works 25222 or 33313250 mower and need a budget-friendly direct replacement. It’s fine for standard residential lawns but skip it if you want a high-lift blade for bagging performance or a mulching blade for fine clippings.
