MaxPower 561739B 2 Blade Set for 46" Cut Craftsman, Husqvarna, Poulan Replaces OEM no. 405380, 594892801, 532405380, CMXGZAM110147

What It Is

This is a set of two 18.0-inch by 2.75-inch (cut to 17.5-inch effective cutting width) replacement blades for 46-inch cutting deck lawn tractors. Designed for mulching, bagging, or side-discharge use on Craftsman, Husqvarna, and Poulan models.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Your mower must have a 46-inch cutting deck. This set covers all three spindles, so you’ll need two sets (four blades total) for most 46-inch decks.
• OEM part numbers: Directly replaces Craftsman/Husqvarna/Poulan OEM numbers 405380, 594892801, 532405380, and CMXGZAM110147. Also fits many AYP, Murray, and MTD models with the same spindle pattern.
• Center hole: 0.75-inch diameter. Measure your spindle’s center hole—if it’s larger (e.g., 7/8-inch or 1-inch), these won’t fit.
• Blade thickness: 0.203 inches (standard for most residential tractors). Verify your old blade thickness matches within 0.01 inch.

Key Things to Know

• Quality: Heat-treated steel with a hardened edge. Lasts 2–3 seasons on a 1/2-acre lot with normal use. Not for commercial mowing.
• Installation difficulty: Easy—requires a socket wrench (5/8-inch or 3/4-inch, depending on your spindle nut). No special tools or blade balancer needed, but balancing is recommended.
• Common gotcha: These blades are straight (not offset or serrated). If your original blades had a different shape (e.g., high-lift or deep-dish), these may reduce bagging efficiency.
• Fitment note: Many 46-inch decks use three blades. This set only includes two—order two sets if you need three blades.

Should You Buy It

Buy this set if you have a 46-inch Craftsman, Husqvarna, or Poulan tractor with a standard spindle pattern and want a no-hassle, direct replacement that matches OEM specs at about half the price. Avoid if your deck uses offset or serrated blades, or if you need professional-grade durability for daily commercial use.
