Husqvarna 532187256 54-Inch Cut Mower Blade For Husqvarna/Poulan/Roper/Craftsman/Weed Eater

What It Is

This is a 54-inch cut lawn mower blade (OEM part 532187256) designed for zero-turn and riding mowers with a 54-inch cutting deck. It is sold as a single blade; you need multiple blades for a full set (typically three for a 54-inch deck).

Fitment & Compatibility

Before buying, confirm:

• Deck size: Your mower must have a 54-inch cutting deck. This blade is not for 42-inch, 48-inch, or 60-inch decks.
• Model/brand: Fits Husqvarna, Poulan, Roper, Craftsman, and Weed Eater mowers with a 54-inch deck. Double-check your model number against the OEM part number 532187256.
• Measurements: Blade length is 20.5 inches, center hole is 1 inch diameter, and the blade is 0.1875 inches thick. Measure your current blade to verify.
• OEM vs aftermarket: This is an OEM Husqvarna part, so it matches factory specs. Aftermarket alternatives may be cheaper but often differ in balance or thickness.

Key Things to Know

• Quality: OEM blades are heat-treated and balanced from the factory. They hold an edge well but dull faster on sandy or rocky soil.
• Installation difficulty: Easy – remove the old blade, clean the spindle, and torque the bolt to 70-90 ft-lbs. Use a blade removal tool or a block of wood to prevent spinning.
• Common gotchas:
  • Do not reuse the old bolt or washer; replace them if worn.
  • Install with the cutting edge facing the direction of rotation (usually marked “this side up”).
  • Check spindle bearings for play before installing – worn spindles will ruin a new blade quickly.

Should You Buy It

If you need a direct replacement for a Husqvarna 54-inch deck mower and want a guaranteed fit with factory durability, this is a solid choice. It’s not the cheapest option, but it avoids the fitment headaches of generic blades. Skip it if you have a different deck size or prefer a mulching or high-lift blade.
