What It Is

This is a set of medium-lift replacement blades designed for 46-inch cutting decks on Husqvarna and compatible lawn tractors. Medium-lift blades balance bagging performance with mulching and side-discharge capability, making them a versatile choice for typical residential lawn care.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and that the blade measures 20.5 inches long with a 1-inch center hole and a 0.25-inch thick body. These blades are direct replacements for OEM part numbers 532405380, 403107, 405380, 532403107, and PP21011. They fit Husqvarna models like YTH22V46, Z246, YT46LS, YTH20K46, YTH21K46, YTH22K46, and YTA22V46, plus many Craftsman, Poulan, and other tractors using the same 46-inch deck pattern. To verify, measure your current blade length, center hole diameter, and mounting pattern (usually a five-point star or oval hole). Cross-check your mower’s model number against the OEM numbers listed.

Key Things to Buy

• Quality: These are aftermarket blades, typically made from hardened steel. They may not last as long as OEM blades if you hit rocks or roots frequently, but for regular grass cutting on a well-maintained lawn, they perform well.
• Installation: Blade installation is straightforward—use a socket wrench and a block of wood to prevent the blade from spinning. Torque the blade bolt to 70–90 ft-lbs. Always disconnect the spark plug first.
• Balance: Aftermarket blades sometimes require balancing before use. Use a blade balancer to check; if one side dips, file the heavy side slightly. Unbalanced blades cause vibration and premature spindle wear.
• Gotchas: Medium-lift blades may not lift wet or tall grass as effectively as high-lift blades, so avoid cutting when grass is damp. Also, ensure your deck is level to get an even cut.

Should You Buy It

If you need a budget-friendly replacement for a 46-inch Husqvarna or compatible tractor and primarily cut dry, average-height grass, these blades are a solid choice. They offer decent lift for bagging and mulching without the aggressive suction of high-lift blades, making them a good all-around option for residential use. For heavy-duty or commercial cutting, consider OEM or high-lift alternatives.
