What It Is

This is a 2-pack of 46-inch medium-lift replacement blades for Husqvarna and Craftsman lawn tractors with 46-inch decks. Designed for mulching and bagging, they work best on residential turf with moderate grass growth.

Fitment & Compatibility

Before buying, measure your existing blade length (must be 46 inches total, end to end) and confirm the center hole is 1 inch diameter with a 5-point star pattern. This set replaces OEM part numbers 532405380, 403107, and Craftsman 594892801. Fits Husqvarna YTH22V46, Z246, RZ 4623, YTH20K46, YTH21K46, YTH22K46, YTA22V46, and equivalent Craftsman models. Double-check your deck size—only for 46-inch decks, not 42 or 54. Aftermarket, not OEM, so verify blade thickness (about 0.203 inches) matches your spindle clearance.

Key Things to Know

• Installation: Requires a socket wrench and torque to 50–70 ft-lbs. Use thread locker if bolts are worn. Easy for DIYers.
• Lift height: Medium lift balances cutting efficiency and power draw—good for most lawns but may struggle in thick, wet grass.
• Balance: Blades come balanced, but check with a balancer after sharpening. Unbalanced blades cause vibration and spindle wear.
• Durability: Heat-treated steel holds an edge longer than budget blades but dulls faster than premium hardened sets.

Should You Buy It

Buy this if you own a 46-inch Husqvarna or Craftsman tractor and want a reliable, affordable replacement for regular mowing on typical turf. It’s a solid value for the price, but if you need heavy-duty mulching or commercial durability, step up to a thicker, high-lift blade.
