What It Is

This is a 2-pack of high-lift mower blades (OEM part number 532405380) designed for Husqvarna 46-inch cutting decks. They are meant for bagging or side-discharge use, not mulching—despite the product title. Each pack includes two blades and two mounting nuts.

Fitment & Compatibility

• Deck size: 46 inches (must measure your deck from blade tip to blade tip).
• Models: Fits Husqvarna YTA22V46, YTH20K46, YTH21K46, YTH22V46, and other Husqvarna/Craftsman/Poulan models with a 46-inch deck using the same spindle pattern.
• OEM vs aftermarket: These are OEM Husqvarna blades (original part #532405380). They replace 594892801 and 532403107.
• Measurements: Each blade is 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch spindle hole. Verify your existing blade length and hole pattern before ordering.
• Not for: 42-inch or 54-inch decks, or any zero-turn mower with a different spindle mount.

Key Things to Know

• High-lift design improves grass lift for better bagging and discharge but creates more drag—expect slightly reduced engine power and fuel efficiency.
• Not mulching blades despite the product title. If you want mulching, look for a low-lift or Gator-style blade.
• Installation difficulty: Easy—just a socket wrench and a block of wood to lock the blade. Torque the nut to 70-80 ft-lbs.
• Common gotcha: The included nuts may be thin. Use a torque wrench to avoid over-tightening or stripping. Replace the blade bolt if it’s worn.

Should You Buy It

Buy this if you have a Husqvarna 46-inch lawn tractor and primarily bag or side-discharge grass. It’s a solid OEM replacement that lifts clippings well and lasts a season or two with normal use. Skip it if you want true mulching blades or have a different deck size.
