Husqvarna

What It Is

This is an OEM Husqvarna replacement blade, designed for use on Husqvarna walk-behind mowers and select compatible models. It ensures clean, even cuts by replacing worn or damaged blades.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., LC 221A, HU775H) and deck size (typically 21 or 22 inches). This blade fits Husqvarna mowers with a 2-in-1 cutting system (mulch and side-discharge). Measure the blade length (usually 21 inches), center hole diameter (1 inch), and thickness (0.125 inches). Confirm it’s not for zero-turn or riding mowers—this is only for walk-behinds. Cross-reference with OEM part numbers like 532 42 79-01 or 532 42 79-02. Aftermarket blades may vary in fit; stick with OEM for guaranteed compatibility.

Key Things to Buy

• Quality: OEM construction ensures sharpness, durability, and balance. Aftermarket blades may be thinner or less precise.
• Installation: Easy—remove the old blade with a socket wrench, install the new one with the sharp edge facing up, and torque to 35-45 ft-lbs. No special tools needed.
• Gotchas: Check for blade adapter or washer reuse; some Husqvarna models require a specific star washer. Always disconnect the spark plug before working.
• Frequency: Replace blades every 25-50 hours of use or if nicked, bent, or dull. Sharpening is possible but not recommended for this price point.

Should You Buy It

Yes, if you own a compatible Husqvarna walk-behind mower and need a reliable, direct-fit replacement. It’s a low-cost, high-quality fix for maintaining cut performance. Avoid if you need a mulching-only or bagging-specific blade, or if your mower uses non-standard hole sizes.
