MaxPower 561742B 2 Blade 3-N-1 Style for 42 Inch Cut Replaces Craftsman/Husqvarna/Poulan OEM #'s 139775, 532139775, 594893101

What It Is

The MaxPower 561742B is a set of two 3-in-1 (mulch, bag, side-discharge) replacement blades for 42-inch cutting decks. Designed for Craftsman, Husqvarna, and Poulan lawn tractors, these blades handle light-to-medium residential mowing with standard grass conditions.

Fitment & Compatibility

• Deck size required: 42-inch cut – measure your deck’s blade span before buying.
• OEM cross-references: Replaces Craftsman 139775 / 532139775 and Poulan 594893101.
• Mounting hole: 5-point star center hole (common on these brands).
• Blade dimensions: 21.25” length, 2.5” width, 0.203” thickness, 0.75” center hole.
• Check your spindle: Verify your tractor’s spindle uses a star-shaped hole (not a round hole or keyed slot).
• Brands confirmed: Fits most Craftsman, Husqvarna, and Poulan tractors with a 42” deck and star-pattern spindle (e.g., Craftsman LT1000/2000 series, Husqvarna YTH22V46, Poulan PPB42T).

Key Things to Know

• Installation: Easy swap with a socket wrench – no special tools required. Torque blade bolts to 70–90 ft-lbs.
• Balance: Blades come pre-balanced, but always double-check with a balancer after installation to avoid vibration.
• Material: Heat-treated steel, not hardened for heavy-duty or rocky terrain – expect faster dulling in sandy or rough lawns.
• Common gotcha: The star hole can be tight on some spindles; lightly file the center if needed. Do not force it.

Should You Buy It

Buy these if you have a 42-inch Craftsman, Husqvarna, or Poulan tractor and want a budget-friendly, drop-in replacement for standard residential mowing. They’re a solid value for the price, but skip them if you need heavy-duty mulching, hit rocks often, or have a different deck size or spindle type.
