MaxPower 561746B 3 Blade Set for Many 61 in. Cut Craftsman, Husqvarna, Poulan Mowers Replaces OEM # 539113312, 510417901

What It Is

This is a 3-blade set designed for 61-inch cut zero-turn and riding mowers, commonly used on Craftsman, Husqvarna, and Poulan Pro models. It replaces OEM part numbers 539113312 and 510417901, and is intended for residential or light commercial mowing.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 61 inches (measured blade tip to tip). This set fits many Husqvarna, Craftsman, and Poulan Pro models with that deck size, but not all—check your model number against MaxPower’s online fitment list. The blades are 20.5 inches long, 2.25 inches wide, with a 1-inch center hole and 0.5-inch offset. They are a direct replacement for OEM blades, but aftermarket blades may have slightly different balance or thickness. Always verify blade length, hole diameter, and offset match your original blades by measuring them.

Key Things to Know

• Quality: Made from heat-treated steel with a hardened edge; generally durable for typical residential use, but may dull faster than premium OEM blades on heavy or rocky terrain.
• Installation: Moderate difficulty—requires lifting the mower, removing old blades with a socket wrench, and torquing new blades to 70-90 ft-lbs. Use a blade removal tool or block the deck for safety.
• Balance: Blades come pre-balanced, but it’s wise to check balance yourself before installing. An unbalanced blade causes vibration and poor cut quality.
• Gotchas: These are not universal—some 61-inch decks use different blade offsets or lengths. Double-check that your deck uses three identical blades (some use a different center blade). If your mower has a washout port, ensure the blade design doesn’t block it.

Should You Buy It

If you have a compatible 61-inch Craftsman, Husqvarna, or Poulan Pro mower and want a cost-effective replacement for worn OEM blades, this set is a solid choice. It’s best for homeowners who mow weekly on typical lawns and don’t need the absolute longest edge life. For rough, rocky, or commercial use, consider OEM or premium aftermarket blades.
