2 Pack 532405380 Mower Blades for Husqvarna 46 Inch Z246 YTH20K46 YTH22V46 YT46LS YTH21K46 RZ4623 YTH2246 Replaces 532403107 594892801 531309715 for Poulan Pro Tractors

What It Is

This is a 2-pack of replacement mower blades (OEM part 532405380) designed for 46-inch cutting decks on select Husqvarna, Poulan Pro, and compatible tractors. They are for medium-to-heavy residential mowing, not commercial use.

Fitment & Compatibility

Deck size must be exactly 46 inches – measure your deck width before buying. These blades fit Husqvarna models: Z246, YTH20K46, YTH22V46, YT46LS, YTH21K46, RZ4623, YTH2246, plus Poulan Pro tractors using OEM numbers 532403107, 594892801, or 531309715. Check your current blade’s part number or cross-reference your model on the manufacturer’s site. The blade length is 20.5 inches, center hole is 1 inch, and the drive pin hole is 7/16 inch. If your deck uses a different spindle or blade pattern, these won’t fit.

Key Things to Know

• Quality: Aftermarket replacements; sharp out of the box but may need balancing before install. Not as durable as OEM Husqvarna blades for heavy abuse.
• Installation: Requires a 15/16-inch or 5/8-inch socket (depending on bolt). Torque to 70-90 ft-lbs. Use a blade removal tool or block the blade to prevent spinning.
• Common gotcha: Double-check that your deck uses two blades (not three) and that the blade’s air-lift shape matches your mower’s discharge direction – these are universal lift, but verify.
• Sharpening: Can be sharpened 2-3 times before replacement. Replace if bent, cracked, or worn past the hard surface.

Should You Buy It

If you own a 46-inch Husqvarna or compatible Poulan Pro tractor and need a budget-friendly, decent-quality replacement for regular residential mowing, this 2-pack offers good value. Skip it if you require OEM-grade longevity or commercial durability.
