532405380 Mower Blades for Husqvarna Z246 YTH22V46 YTH20K46 YTH21K46 YTA22V46 Tractors Replaces Husqvarna 46 inch Mower Blades Craftsman 403107(High Lift)

What It Is

This set of three 46-inch high-lift mower blades is designed for Husqvarna Z246, YTH22V46, YTH20K46, YTH21K46, and YTA22V46 tractors, plus compatible Craftsman 46-inch deck models. The high-lift design increases airflow under the deck for better grass discharge and bagging performance.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 46 inches (measured blade tip to tip). These blades replace OEM Husqvarna 532405380 and Craftsman 403107. They fit Husqvarna Z246 zero-turn, YTH22V46, YTH20K46, YTH21K46, and YTA22V46 lawn tractors. Also fits many Craftsman 46-inch deck models using the same spindle pattern. Measure your current blade length (should be 20.5 inches), center hole diameter (typically 1 inch), and spindle mount pattern (three-point star or oval). Verify your deck uses three blades, not two. Check your owner’s manual for exact OEM part numbers to confirm this aftermarket replacement matches.

Key Things to Know

• High-lift design improves bagging but increases wear – The aggressive lift creates more suction, which helps in thick or wet grass but dulls faster than standard blades. Expect to sharpen more often.
• Installation is straightforward but requires safety steps – Disconnect the spark plug, block the deck, and use a blade removal tool. Torque blade bolts to 30-40 ft-lbs. Mark blade orientation before removal.
• Check deck clearance before first use – High-lift blades sit slightly lower. Ensure your deck height adjustment allows full range without scalping. Test on a flat surface before mowing.
• Balancing is recommended – Aftermarket blades may need balancing. Use a blade balancer tool. Unbalanced blades cause vibration, poor cut, and spindle wear.

Should You Buy It

If you own one of the listed Husqvarna or Craftsman 46-inch deck models and need reliable, affordable replacements for bagging or mulching, these high-lift blades are a solid choice. The 4.8-star rating reflects good value and fitment accuracy. They’re best for users who bag grass frequently and don’t mind slightly faster blade wear. Avoid if you primarily side-discharge or mow fine turf—standard lift blades may be gentler.
