Oregon Mower Blade, 21 Inches, Replaces Many Husqvarna Blades

What It Is

This Oregon 21-inch mower blade is a replacement blade designed for walk-behind mowers, specifically compatible with many Husqvarna models. It’s a standard mulching or bagging blade for residential lawn care.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Blade length is exactly 21 inches. Measure your current blade from tip to tip. Must match your deck’s maximum blade length.
• Model/brand fit: Oregon lists this as a replacement for many Husqvarna blades (e.g., part numbers 532 44-10-93, 532 41-13-03). Verify your mower model against Oregon’s compatibility chart. It also fits some Poulan, Craftsman, and McCulloch models.
• Key measurements: Center hole diameter is 1 inch (standard for most walk-behinds). Blade thickness is 0.125 inches. If your mower uses a different hole size or a star-shaped center, this won’t fit.
• OEM vs aftermarket: This is an aftermarket blade. It’s not a Husqvarna OEM part, so it may have slight differences in steel grade or balance. Works fine for most users, but check if your mower warranty requires OEM parts.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand. These blades are made from hardened steel and hold an edge reasonably well. They’re not premium (like Gator blades), but they’re solid for the price.
• Installation difficulty: Easy – remove the old blade, install with the “this side up” markings facing the deck. Torque to 30-40 ft-lbs. No special tools beyond a socket wrench.
• Common gotchas: The blade may need balancing before first use (use a blade balancer). Also, it’s a straight-edge mulching blade, not a high-lift blade – won’t throw grass as far in bagging mode.
• Reviews: Only 4 reviews at 4.7 stars, so take the rating with caution. Early buyers report good fit and sharpness.

Should You Buy It

Buy this if you have a 21-inch deck Husqvarna mower, want a reliable, affordable replacement blade, and don’t need a premium high-lift or mulching blade. Skip it if you require OEM parts for warranty, need a different blade length or center hole size, or prefer a blade with more aggressive lift for wet grass.
