532405380 Mower Blades for 46" Lawn Tractor, 405380 High Lift Blades for Hu sqvarna YTH22V46, YTH20K46, Craftsman YT3000 46" Deck, Replace for PP21011, 532403107, 2 Pack

What It Is

This is a two-pack of high-lift mower blades (OEM reference 532405380 / 405380) designed for 46-inch cutting decks on Husqvarna and Craftsman lawn tractors. The high-lift profile improves grass discharge and bagging performance, especially in thick or damp grass.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Only fits 46-inch decks. Measure your deck’s cutting width (blade tip to blade tip) to be sure.
• Model compatibility: Direct replacement for Husqvarna YTH22V46, YTH20K46, and Craftsman YT3000 with 46" deck. Also replaces OEM part numbers PP21011 and 532403107.
• Blade measurements: Each blade is 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and 5-point star drive. Check your current blade’s center hole and drive pattern – if it’s a round hole or different star pattern, these won’t fit.
• Aftermarket note: These are non-OEM blades. They match the OEM specs but may have slight finish differences. Verify your spindle and blade bolt size (typically 5/8" or 3/4") before installing.

Key Things to Know

• High lift = more suction: Great for bagging and side discharge, but can create more dust and wear faster in sandy or dry conditions.
• Installation: Straightforward swap – use a socket and torque wrench (blade bolts typically need 70-80 ft-lbs). No special tools beyond a blade removal tool or block of wood to lock the blade.
• Common gotcha: These blades are sharp out of the box. Wear gloves during installation, and always disconnect the spark plug before working under the deck.
• Balance check: Aftermarket blades can sometimes be slightly off-balance. Spin each blade on a balancer or nail before installing; file the heavy side if needed.

Should You Buy It

If you own a Husqvarna or Craftsman 46-inch tractor and need affordable high-lift blades for better bagging or discharge in heavy grass, this two-pack is a solid value. Not ideal for mulching (low-lift blades work better) or for decks with odd spindle patterns. For $25.99, it’s a reliable replacement that matches OEM specs without the OEM price.
