MaxPower 561741B 3 Blade Set for Many 52 in. Craftsman, Husqvarna, Poulan Mowers Replaces OEM #'s 870801, 574870801, 575240701

What It Is

This is a set of three 52-inch mower blades designed for high-end residential and light commercial use, replacing OEM blade sets on many Craftsman, Husqvarna, and Poulan zero-turn and lawn tractor models. It’s meant for mulching, bagging, or side-discharge cutting on decks requiring a three-blade configuration.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This set fits 52-inch cutting decks only. Measure your deck width—if it’s 46, 48, or 54 inches, this set won’t work.
• Blade measurements: Each blade is 17.5 inches long, 2.75 inches wide, with a 0.25-inch thickness and a 5-point star center hole. Measure your current blade length and hole pattern to confirm match.
• OEM cross-reference: Replaces OEM #s 870801, 574870801, and 575240701. If your mower uses these numbers, it’s a direct swap. Common compatible models include Craftsman 917.27xxxx, Husqvarna YTH24V48, and Poulan Pro PPB52.
• Brand fit: Works on many, but not all, 52-inch decks from these brands. Check your owner’s manual or current blade part number against the OEM list. Aftermarket sets may have slight weight or balance differences from OEM.

Key Things to Know

• Quality: Made from heat-treated, tempered steel. Most users report good durability for residential use, but some note they dull faster than OEM on rocky or sandy soil.
• Installation difficulty: Easy—remove the old blades, install new ones with the “wind” side (raised edge) facing up toward the deck. Torque bolts to 70-80 ft-lbs. No special tools needed beyond a socket wrench.
• Common gotchas: The star hole pattern is specific—if your mower uses a round hole or different center design, these won’t fit. Also, verify you need three blades; some 52-inch decks use two.
• Balance: Each blade is individually balanced, but it’s good practice to check with a blade balancer after mounting to avoid vibration.

Should You Buy It

If you own a 52-inch Craftsman, Husqvarna, or Poulan mower that uses one of the listed OEM part numbers, this is a reliable, cost-effective replacement. It’s best for homeowners mowing standard lawns—avoid if you need heavy-duty commercial blades for very rough terrain or frequent wet grass.
