Parts Camp 2 Pack 405380 532405380 403107 532403107 Lawn Mower Blades for Husqvarna Craftsman 46 Inch Deck Riding Mowers, Fits YTH22V46 YTA22V46 YTH20K46 YTH21K46 YTH22K46, 5 Point Star Hole

What It Is

This is a 2-pack of aftermarket replacement mulching blades designed for 46-inch deck riding mowers from Husqvarna and Craftsman, primarily for residential lawn care. They feature a 5-point star center hole to match OEM mounting patterns.

Fitment & Compatibility

Before buying, verify your mower has a 46-inch cutting deck and a 5-point star spindle pattern (not a 3-point or round hole). These blades fit Husqvarna YTH22V46, YTA22V46, YTH20K46, YTH21K46, YTH22K46, and many Craftsman models with the same deck. Measure your existing blade length—these are typically 18.25 inches long, 2.5 inches wide, with a 0.25-inch thickness. Cross-reference OEM part numbers 405380 and 403107 to confirm compatibility. Not for 42-inch or 54-inch decks.

Key Things to Know

• Quality: Aftermarket steel blades, not OEM; adequate for standard grass but may dull faster on thick or rocky terrain.
• Installation: Easy swap with basic tools (socket wrench). Ensure blades are oriented with cutting edge facing the direction of rotation—check your mower’s manual.
• Gotcha: The 5-point star hole fits Husqvarna/Craftsman spindles only; will not work on John Deere or MTD models with different center patterns.
• Maintenance: Sharpen or replace after 25 hours of use or when grass tears instead of cuts. Balance new blades after sharpening to avoid vibration.

Should You Buy It

If you own a compatible Husqvarna or Craftsman 46-inch riding mower and want an affordable, no-frills replacement for standard mulching, this 2-pack is a solid value. Not ideal for commercial use or heavy-duty cutting where OEM durability or longer life is critical.
