405380 532405380 Lawn Mower Blades for Husqvarna Craftsman 46 Inch Deck Medium Lift Blades Riding Mower Replacement for 594892801 532403107 YTH22V46 CMXGZAM110147 PP21011 2Pack

What It Is

This is a set of two medium-lift replacement blades designed for 46-inch cutting decks on Husqvarna and Craftsman riding mowers. The medium lift profile balances grass clipping discharge and bagging performance, making it a solid choice for typical residential lawn care.

Fitment & Compatibility

Before buying, measure your existing blade length (should be roughly 20.5 inches from tip to tip) and confirm a 5-point star center hole and 1-inch diameter. This 2-pack replaces OEM part numbers 532403107, 594892801, 532405380, and 405380. It fits specific Husqvarna YTH22V46 and Craftsman CMXGZAM110147, PP21011, and similar 46-inch deck models. Verify your deck size is exactly 46 inches (measured blade tip to blade tip) and that your mower uses a medium-lift blade originally. Cross-check your model number against the manufacturer’s approved blade list—some decks use high-lift or mulching blades only.

Key Things to Know

• Quality: Made from heat-treated steel, these are durable for residential use but may dull faster than OEM if you hit rocks or roots often.
• Installation: Medium difficulty—you’ll need a socket wrench and a block of wood to jam the blade. Torque bolts to 70–90 ft-lbs. Always disconnect the spark plug first.
• Balance: New blades should be balanced before mounting. Even minor imbalance can cause vibration and damage spindle bearings.
• Common gotcha: The star center hole fits most Husqvarna/Craftsman spindles, but some aftermarket spindles use a different pattern—check your spindle nut shape.

Should You Buy It

If you own a Husqvarna or Craftsman 46-inch deck riding mower and need a reliable, budget-friendly replacement for standard cutting and bagging, this is a solid pick. It’s not for heavy-duty commercial use or decks requiring high-lift or mulching-only blades.
