MAXPRO Mower Mulching Blade Compatible with Husqvarna 46 Inch YTH22V46 Z246 RZ4623 Fits Craftsman Poulan Pro Replaces 532403107 CMXGZAM110146 (403107)

What It Is

This is a set of three mulching blades designed to replace the OEM part 532403107 (403107) on select Husqvarna, Craftsman, and Poulan Pro riding mowers with a 46-inch cutting deck. Mulching blades feature a curved, wing-like design that recuts grass clippings into fine particles to be returned to the lawn as natural fertilizer.

Fitment & Compatibility

• Deck size: Only fits 46-inch (46") mower decks. Measure your deck before ordering.
• Compatible models: Husqvarna YTH22V46, Z246, RZ4623; Craftsman T2200, T2300; Poulan Pro PR46ST, PP46ST. Check your model number against the product listing.
• OEM reference: Directly replaces Husqvarna/Craftsman part 532403107 (also CMXGZAM110146, 403107).
• Blade dimensions: Typically 20.5" long, 2.5" wide, 0.25" thick with a 1" center hole and 7-point star drive. Measure your old blade to confirm.
• Center hole: Must match your spindle’s star pattern. If your OEM blade has a different drive shape, this won’t fit.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish. Not as thick or durable as OEM or premium aftermarket blades—expect shorter sharpness life (20–30 hours of mowing).
• Installation: Moderate difficulty. You’ll need a torque wrench (tighten to 70–90 ft-lbs) and a blade removal tool. Always disconnect the spark plug first.
• Gotcha: Some users report the blades are slightly lighter than OEM, which can cause vibration at high RPM. Check balance before installing.
• Mulching performance: Works best in dry grass; wet or tall grass may clump. Not designed for bagging or side discharge—strictly mulching.

Should You Buy It

This blade set is a solid budget option if you need a quick, direct-fit replacement for a 46-inch Husqvarna or Craftsman mower and you primarily mulch in dry conditions. It’s not the longest-lasting choice, but at $29.99 with solid ratings, it’s fine for light-to-moderate use. For heavy-duty mowing or wet grass, consider OEM or a thicker aftermarket blade.
