What It Is

This is a 2-pack of 46-inch deck mower blades (OEM part 532405380 / 405380) designed for AYP/Craftsman/Husqvarna/Poulan/Pro lawn tractors. They mulch and discharge grass, and are a direct replacement for worn or damaged blades on select 46-inch cutting decks.

Fitment & Compatibility

• Deck size: Must be a 46-inch cutting deck. Measure your deck or check your mower’s model number.
• Fits: Husqvarna YTH22V46, YTH20K46; Craftsman YT3000, YT4000; Poulan Pro; AYP-built models with 46" stamped decks.
• Replaces: OEM 532405380, 532403107, and aftermarket PP21011.
• Measurements: Blade length is 20.5 inches, center hole 1 inch, 5-point star drive. Confirm your spindle matches this star pattern—some older decks use a round hole with a key.
• Aftermarket note: These are not OEM Craftsman/Husqvarna blades. They are aftermarket replacements that match OEM specs.

Key Things to Know

• Sharpness out of box: Most users report they are sharp and balanced, but always check for edge burrs before installing.
• Installation: Straightforward swap—use a torque wrench to tighten spindle bolts to 50-70 ft-lbs. No special tools needed beyond a socket and breaker bar.
• Common gotcha: The star drive center hole is specific. If your spindles use a round hole with a keyway or different star pattern, these won’t fit.
• Durability: Aftermarket steel—good for residential use, but may dull faster than OEM on sandy or rocky lawns.

Should You Buy It

If you own a 46-inch AYP/Craftsman/Husqvarna tractor and need a cost-effective 2-pack for regular seasonal blade changes, this is a solid buy. It’s not for commercial use or oddball spindle patterns, but for most homeowners, it’s a reliable drop-in replacement at a fair price.
