Husqvarna 255-8T 10" Grass Blade

What It Is

The Husqvarna 255-8T 10" Grass Blade is a 10-inch, 3-in-1 mulching, bagging, and discharge blade designed for walk-behind mowers with small decks (typically 21" or smaller). It’s intended for residential use on standard turf grass, not heavy brush or thick weeds.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This blade fits mowers with deck openings that accept a 10-inch blade. Measure your current blade’s length from tip to tip—if it’s exactly 10", this will work. Common on 21" decks.
• Center hole and drive system: The 255-8T has a 1-inch round center hole and a 7-point star drive. Check your mower’s spindle—most Husqvarna, Poulan Pro, and Craftsman walk-behinds use this pattern, but some older or non-Husqvarna models may use a square or oval hole.
• OEM vs aftermarket: This is an OEM Husqvarna blade (part #532429554). It fits Husqvarna, Jonsered, and many Poulan Pro models, but not universal. Cross-check your mower’s model number against Husqvarna’s compatibility list online.

Key Things to Know

• Installation difficulty: Easy—one bolt, no special tools beyond a socket wrench. Torque to 30-40 ft-lbs. Use a blade removal tool if the bolt is rusted.
• Blade type: It’s a “medium-lift” blade—good for mulching and bagging, but not great for side discharge on thick, wet grass. Expect some clumping if you mow wet.
• Durability: Heat-treated steel, holds an edge well for residential use. Not for commercial or rocky yards—expect to replace every 1-2 seasons.
• Balance check: Always balance a new blade before installing. Even OEM blades can be slightly off. A $10 blade balancer saves your spindle bearings.

Should You Buy It

Yes, if you have a Husqvarna or compatible walk-behind mower with a 10-inch blade and want a reliable OEM replacement for mulching or bagging. It’s not the cheapest aftermarket option, but the fit is guaranteed, and the quality matches the mower’s design. Skip it if you need a high-lift blade for side discharge or have a non-Husqvarna deck with a different drive pattern.
