Husqvarna 532421825 Premium Blade Replacement for Lawn Mowers, 22"

What It Is

The Husqvarna 532421825 is a 22-inch OEM replacement blade designed for Husqvarna walk-behind mowers with stamped steel decks. It’s a medium-lift blade suited for standard residential grass cutting, not mulching or bagging.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This blade is exactly 22 inches long (measured diagonally from tip to tip). Measure your current blade or deck width—if your deck is 21 or 22 inches, it will likely fit.
• Center hole: It has a 5-point star center hole (Husqvarna’s common pattern). Check that your mower’s spindle matches this design—older or non-Husqvarna models may use a round hole or different star pattern.
• Model compatibility: Fits most Husqvarna walk-behinds from the 2000s onward (e.g., 7021P, 961410017). It also fits some Poulan Pro and Craftsman models with the same star pattern. Search your mower’s model number in Husqvarna’s parts lookup to confirm.

This is an OEM part, not a universal aftermarket blade. Using it on a different brand (e.g., Toro, Honda) is unlikely to work without adapter hardware.

Key Things to Know

• Quality: Made from hardened steel with a coated finish to resist rust. Sharp out of the box—handle with gloves.
• Installation difficulty: Easy (15 minutes). You’ll need a wrench or socket for the center bolt. Torque to 30–40 ft-lbs; overtightening can strip the spindle.
• Common gotcha: This blade is not reversible or dual-sided. Replace when dull or bent—never try to sharpen it more than twice, as it can become unbalanced.
• Performance: Best for light-to-medium grass. Thick or wet grass may leave clumps; consider a high-lift blade if you mow tall or damp lawns regularly.

Should You Buy It

Buy it if you own a compatible Husqvarna walk-behind and want a drop-in OEM replacement that matches factory specs. Skip it if you need a mulching blade, have a non-Husqvarna mower, or prefer a universal aftermarket option for less money.
