Husqvarna 255-4T 10" Grass Blade

What It Is

The Husqvarna 255-4T is a 10-inch, 4-tooth grass blade designed for use with Husqvarna’s 200-series walk-behind mowers and compatible trimmers/brushcutters with a blade adapter. It’s meant for general grass cutting, not mulching or heavy brush.

Fitment & Compatibility

• Deck size: For mowers with a 10-inch blade path—check your mower’s deck measurement (usually stamped on the blade or in the manual).
• Model/brand fit: Direct OEM replacement for Husqvarna 200-series mowers (e.g., 225RH, 225RX). Also fits some Craftsman, Poulan, and Jonsered models using the same blade adapter. Verify your mower’s model number before buying.
• OEM vs aftermarket: This is an OEM Husqvarna blade (part # 255-4T). Aftermarket equivalents exist but may vary in thickness or balance.
• Measurements: Blade length: 10 inches (254 mm). Center hole: 20 mm (0.787 in). Blade thickness: ~0.06 in (1.5 mm). Check your spindle’s hole size and bolt pattern.
• What to check: Remove your old blade and compare length, center hole diameter, and bolt pattern. If using a brushcutter, ensure you have the correct blade adapter (sold separately).

Key Things to Know

• Quality: Heat-treated steel, sharp out of the box. Holds edge well for residential use.
• Installation difficulty: Easy—requires a wrench and blade stop tool. Torque to 30-40 ft-lbs. Use thread locker if reusing old bolts.
• Common gotchas:
  • 4-tooth design is for grass only—will clog in wet or tall weeds.
  • Not compatible with “universal” blade adapters; needs Husqvarna’s specific adapter for trimmers.
  • Balance-check before installation (mark blade edge, hang on a nail—if one side dips, it’s off).
• Replacement interval: Replace after 25 hours of use or when nicked/bent—dull blades tear grass, causing brown tips.

Should You Buy It

Buy this if you own a Husqvarna 200-series mower or compatible trimmer and need a direct OEM replacement for standard grass cutting at a fair price. It’s a solid choice for homeowners who want reliable, sharp performance without aftermarket guesswork. Skip it if you need a mulching blade or plan to cut heavy weeds.
