Grasscool YTH22V46 5 Star High Lift Mower Blades for Husqvarna 46 inch Zero Turn Replace 405380 Z246 YTH20K46 YTH21K46 YTH22K46 YTA22V46 Lawn Tractor Riding 532405380

What It Is

The Grasscool YTH22V46 5 Star High Lift Mower Blades are aftermarket replacement blades designed for Husqvarna 46-inch cutting decks, providing superior grass lift and mulching performance for residential zero-turn mowers and lawn tractors.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 46 inches (measured blade tip to tip). These blades replace OEM part #532405380 (also #405380). Compatible with Husqvarna models Z246, YTH20K46, YTH21K46, YTH22K46, YTH22V46, and YTA22V46. Also fits some Craftsman, Poulan, and McCulloch models with the same deck. Measure your existing blade length (should be 18.5 inches), center hole diameter (1 inch), and thickness (0.25 inch). Verify the spindle pattern matches your deck—these are 5-star (5-point) blades, not standard 3-point. Check your deck’s blade bolt torque spec (typically 70-90 ft-lbs).

Key Things to Know

• High-lift design improves grass discharge and bagging, but requires more engine power and may leave stripes on wet or tall grass.
• Installation is straightforward with basic hand tools (socket wrench and blade removal tool). Always disconnect the spark plug and block the blade before removal.
• Sharpen or replace every 25-30 hours of use. High-lift blades dull faster than standard blades if used on sandy or rocky lawns.
• Balance after sharpening is critical—unbalanced blades cause vibration, spindle wear, and poor cut. Use a blade balancer.

Should You Buy It

Buy these if you need a reliable, affordable high-lift replacement for your Husqvarna 46-inch deck and want better grass lift and bagging than standard blades. They’re ideal for residential use with regular mowing schedules, but avoid them if you mow very wet, thick, or uneven terrain where high-lift blades can clog or scalp.
