561739B Medium-Lift Lawn Mower Blade for 46" Deck, fit for Husqvarna YTH22V46 YTH20K46, Replace for Craftsman Poulan 405380, 532-405380, PP21011, 403107, AYP 561739, 2PK

What It Is

This is a set of two medium-lift lawn mower blades designed for 46-inch cutting decks. They are intended for residential mowing on Husqvarna YTH22V46 and YTH20K46 tractors, and serve as a replacement for several Craftsman, Poulan, and AYP models.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 46 inches (blade length is typically 20.5 inches, center hole diameter 1 inch, and thickness 0.1875 inches). These blades fit Husqvarna YTH22V46 and YTH20K46, and also replace Craftsman/Poulan part numbers 405380, 532-405380, PP21011, 403107, and AYP 561739. They are aftermarket, not OEM, so verify your spindle pattern matches (two holes, 3.5 inches center-to-center). Check your current blade’s part number against the list above to ensure a direct swap.

Key Things to Know

• Medium lift: Good for bagging and general mulching on flat to moderately hilly lawns. Not ideal for heavy mulching or wet, thick grass.
• Installation: Straightforward if you have a socket wrench and blade removal tool. Torque to 40-50 ft-lbs. No special adapters needed for standard spindles.
• Quality: Steel is adequate for residential use; may dull faster than OEM on rocky or sandy soil. Sharpening is possible but not recommended more than 2-3 times.
• Gotcha: These are sold as a 2-pack, but some decks require three blades. If your 46-inch deck has three spindles, you need two packs (4 blades total). Check your deck layout first.

Should You Buy It

Buy these if you own a compatible Husqvarna or Craftsman 46-inch deck tractor and need a budget-friendly, medium-lift blade for regular bagging or light mulching. Avoid if you have a three-blade deck, need heavy-duty mulching performance, or prefer OEM parts for exact fit and durability.
