What It Is

This is a set of two high-lift 46-inch mower deck blades designed for Husqvarna lawn tractors and zero-turn mowers. They replace OEM part numbers 532405380, 405380, 403107, 561739b, 532403107, and 531309715, intended for models like YTA22V46, YTH22V46, RZ4619, Z246, YTH22K46, and YTH2146.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck (measure cutting width, not chassis). These blades fit Husqvarna models listed above, but also cross-compatible with some Craftsman, Poulan Pro, and AYP models using the same OEM numbers. Check blade length (should be ~20.5 inches), center hole diameter (usually 1 inch), and drive pin or star pattern. Remove one existing blade and compare shape—high-lift blades have a pronounced upward curve at the trailing edge. If your deck uses a different spindle or blade pattern (e.g., 5-point star vs. oval hole), these won’t fit.

Key Things to Know

• High-lift blades create stronger airflow for better bagging and discharge, but may increase engine load and wear faster in sandy/rocky conditions.
• Installation is straightforward: use a torque wrench (40–50 ft-lbs), and apply anti-seize to spindle bolts to prevent rust seizing.
• Always replace blades in sets to maintain balance; an unbalanced set causes vibration, poor cut, and spindle damage.
• Check blade thickness (typically 0.25–0.30 inches) to ensure it matches your spindle’s washer and bolt setup—too thick can prevent proper seating.

Should You Buy It

If you need reliable high-lift blades for a 46-inch Husqvarna (or compatible model) and prioritize bagging or clean discharge over mulch performance, this 2-pack at $30.99 is a solid value. It’s best for users comfortable with basic DIY replacement and who want OEM-equivalent quality without the brand markup. Avoid if your deck uses standard (low-lift) blades for mulching or if you have a different deck size.
