Husqvarna OEM403107 46-Inch Mulch Blade Kit - 2 Pack

What It Is

This is a genuine Husqvarna OEM 46-inch mulch blade kit (two blades) designed to replace worn blades on select Husqvarna and compatible riding mowers. It’s intended for mulching—chopping clippings fine to return nutrients to the lawn—rather than bagging or side-discharge.

Fitment & Compatibility

• Deck size: 46-inch cutting deck only. Measure your deck width to confirm—this kit won’t fit 42-inch or 54-inch decks.
• Model fit: Works with Husqvarna YTH, TS, and GT series (e.g., YTH22V46, TS146X). Also fits some Craftsman, Poulan Pro, and AYP-branded mowers with a 46-inch deck and the same spindle pattern.
• Check blade length and center hole: Each blade is ~20.5 inches long with a 1-inch center hole and 5-point star pattern. Measure your old blade’s length and hole shape before buying—non-standard patterns won’t match.
• OEM vs aftermarket: OEM403107 is genuine Husqvarna. Aftermarket blades may be cheaper but often lack the same steel thickness or balance. For exact fit, stick with OEM.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool (or a block of wood to hold the blade). Torque bolts to 70-90 ft-lbs. No special skills needed.
• Mulching performance: These blades have a higher lift and curved design to recirculate clippings. Works best with a mulch plug installed (sold separately if your mower didn’t come with one).
• Common gotcha: Don’t mix with standard lift blades—using mulch blades for bagging reduces airflow and may clog. Also, sharpen or replace annually; dull blades tear grass and cause brown tips.
• Quality: OEM steel holds an edge longer than budget aftermarket options. The 2-pack covers one full deck swap.

Should You Buy It

Buy this if you own a 46-inch Husqvarna (or compatible) riding mower and want reliable OEM mulching blades that fit without guesswork. It’s a solid choice for average lawn size (1-2 acres) where mulching is your primary mowing method. Skip it if you need bagging blades or have a non-46-inch deck—wrong fit or wrong function.
