405380 High Lift Blades for 46" Deck, 532405380 Lawn Mower Blades Compatible with Hus-qvarna YTH22V46 YTH21K46, Craftsman YT3000, Pou LAN Pro, Replaces 403107, 21546611, 2 Pack

What It Is

This is a set of two high-lift lawn mower blades designed for 46-inch cutting decks, intended to improve grass clipping discharge and bagging performance on select Husqvarna, Craftsman, and Poulan Pro riding mowers. They are an aftermarket replacement for OEM part 532405380 and cross-reference numbers 403107 and 21546611.

Fitment & Compatibility

Before buying, verify your mower has a 46-inch deck (measure blade tip to tip or deck housing width). These blades fit Husqvarna YTH22V46, YTH21K46, Craftsman YT3000, and Poulan Pro models with a 46-inch deck using a center hole diameter of 1 inch and a 5-point star drive. They replace OEM part 532405380, as well as 403107 and 21546611. Check your current blade’s length (likely 20.5 inches) and ensure the spindle pattern matches—these use a 5-point star, not a round hole or keyed.

Key Things to Know

• Installation difficulty: Easy if you have a socket wrench and a blade removal tool (or block the blade to prevent spinning). Torque bolts to 70–90 ft-lbs.
• Quality: Made from heat-treated steel; some users report they are slightly thinner than OEM blades but hold an edge well for residential use.
• Gotcha: High-lift blades create more suction, which can strain the engine on wet or thick grass—avoid mowing when grass is damp to reduce clogging and belt wear.
• Pack quantity: Two blades per pack—enough for a standard 46-inch deck (requires two blades, not three like some 54-inch decks).

Should You Buy It

Buy these if you own a compatible 46-inch deck Husqvarna, Craftsman, or Poulan Pro rider and want better bagging or discharge performance than standard blades. They’re a solid value at $25 for a two-pack, with strong user reviews for durability and fit. Skip them if your deck size is different, your spindle uses a round hole, or you primarily mulch—low-lift or mulching blades would serve better.
