2PCS YTH22V46 46 inch Mower Blades Compatible with Craftsman, Husqvarna, Poulan Z246 YTH20K46 YTH21K46 YTH22K46 YTA22V46 RZ4623 YT3000 with 46'' Deck Replace OE 405380, 532405380

What It Is

This is a set of two 46-inch replacement mower blades designed for medium-duty residential mowing on Craftsman, Husqvarna, Poulan, and similar tractors with a 46-inch stamped deck. They match OEM part numbers 405380 and 532405380.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 46 inches (blade tip to blade tip). These blades fit models like Craftsman YTH22V46, YTA22V46, YT3000; Husqvarna YTH20K46, YTH21K46, YTH22K46; Poulan Z246; and RZ4623. They are aftermarket replacements, not OEM Craftsman parts. Measure your existing blade length (should be about 20.5 inches), center hole diameter (typically 1 inch), and offset (usually 0.5 to 0.75 inch). Verify your spindle pattern—these use a standard 5-point star or oval hole. If your deck has a different spindle design, they won’t fit.

Key Things to Know

• Quality: These are stamped steel blades, not hardened or coated. They’ll dull faster on thick, wet grass or rocky terrain than premium or OEM blades.
• Installation: Simple DIY—requires a socket wrench and torque wrench (recommended 70-90 ft-lbs). Always lift the deck, block securely, and disconnect the spark plug.
• Balance: Aftermarket blades sometimes arrive slightly out of balance. Test with a blade balancer—if off, file the heavy side lightly until balanced to avoid vibration and spindle wear.
• Wear Indicators: Check for bent tips, cracks, or significant dulling after 10-15 hours of use. Replace sooner if you see nicks from hitting debris.

Should You Buy It

If you have a common 46-inch Craftsman or Husqvarna tractor and need a quick, budget-friendly replacement for routine mowing on a well-maintained lawn, these are a solid value. Avoid them if you mow heavy, wet grass, large acreage, or need longer life—step up to a hardened or mulching-style blade instead.
