405380 Mower Blades for Hu sqvarna Craftsman Poulan Pro 46" Lawn Tractor, 532405380 High Lift Blades for Hu sqvarna YTH22V46, YTH20K46, Craftsman YT3000 46" Deck, Replace PP21011, 532403107

What It Is

This is a set of three high-lift mower blades (OEM part number 532405380) designed for 46-inch cutting decks on Husqvarna, Craftsman, and Poulan Pro lawn tractors. High-lift blades create stronger airflow for better grass discharge and bagging performance, ideal for thick or tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck—this is non-negotiable. Check your owner’s manual or look for the model number on the deck itself (often stamped near the blade spindle). These blades replace OEM part numbers 532405380, 532403107, and aftermarket PP21011. They fit many Husqvarna YTH22V46, YTH20K46, and Craftsman YT3000 models, but also work on select Poulan Pro, Weed Eater, and McCulloch tractors with a 46-inch deck. Measure your old blade’s length (should be ~20.5 inches), center hole (1-inch diameter), and offset (0.5-inch). If your current blade has a different hole pattern or offset, these won’t fit.

Key Things to Know

• High lift vs. standard: These blades generate more lift, which helps bagging but can increase engine load and wear in dry, sandy conditions. Avoid them if you mostly mulch.
• Installation: Easy swap with a socket wrench and torque wrench (aim for 70-90 ft-lbs). Always lift the deck and disconnect the spark plug first.
• Balance check: Even if they’re pre-balanced, test on a blade balancer after installation—unbalanced blades cause vibration and damage spindles.
• Sharpening: You can sharpen them 2-3 times before replacement. Don’t overheat the steel (use a file, not a grinder), and never sharpen past the hardened edge.

Should You Buy It

Buy these if you have a 46-inch Husqvarna, Craftsman, or Poulan Pro tractor and need better bagging or discharge performance in thick grass. They’re a solid value at $26, with high user satisfaction (4.7 stars from over 400 reviews). Skip them if you primarily mulch or have a smaller deck.
