MaxPower 561743B Blade Set for 48" Cut Poulan, Husqvarna, Craftsman Replaces OEM no. 539-113425, 48 Inch, Black

What It Is

This MaxPower 561743B blade set is a direct replacement for the OEM 539-113425 blade assembly, designed for 48-inch cutting decks on select Poulan, Husqvarna, and Craftsman lawn tractors. It’s a three-blade set intended for residential mowing on standard turf and grass.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Your deck must be exactly 48 inches. Measure from outer blade tip to outer blade tip if unsure.
• Brand & model: Fits most Poulan, Husqvarna, and Craftsman tractors with a 48-inch deck that originally used OEM 539-113425. Check your owner’s manual or existing blade part number.
• Blade dimensions: Each blade is 16.5 inches long, 2.25 inches wide, with a 5/8-inch center hole and a 0.25-inch thickness. Measure your old blade to verify.
• OEM vs aftermarket: This is an aftermarket part. It’s not identical in finish to OEM, but it matches critical dimensions and mounting pattern. If you need exact OEM appearance, stick with the original.

Key Things to Know

• Quality: Made from heat-treated steel. Users report it cuts well but may dull faster than premium OEM blades on rocky or sandy soil.
• Installation: Moderate difficulty. You’ll need a torque wrench (recommended 70–90 ft-lbs) and a blade removal tool. The blades are sharp—wear gloves.
• Balance: Check balance before installing. Some users report slight imbalance out of the box; a simple blade balancer can fix this.
• Common gotcha: The center hole fits most spindles, but confirm your spindle shaft is 5/8-inch diameter. If you have a different spindle size, this set won’t fit.

Should You Buy It

Buy this set if you need a budget-friendly, drop-in replacement for a 48-inch Poulan, Husqvarna, or Craftsman tractor and don’t require the exact OEM look or premium steel. It’s a solid choice for routine residential mowing on clean lawns. Skip it if you mow heavy weeds, rocks, or need maximum durability—then go with a thicker OEM or high-end aftermarket blade.
