(3) Replacement Blades for 145708 159705 170698 176084 46" Deck Fits Craftsman Fits Poulan Fits Husqvarna Wizard.

What It Is

This is a set of three replacement blades for 46-inch cutting decks, designed for Craftsman, Poulan, Husqvarna, and Wizard lawn tractors. They are for mulching or bagging grass on residential properties.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 46 inches (the blade length is typically 20.5 inches from tip to tip). These blades replace OEM part numbers 145708, 159705, 170698, and 176084. They fit many Craftsman (e.g., 917 series), Poulan Pro, Husqvarna, and Wizard models with a 46-inch deck and a 5-point star center hole. Check your current blade’s part number and center hole shape—these won’t fit decks with a 7-point star or a different hole pattern. Verify your deck’s spindle orientation; these are universal, but some decks require offset or gator-style blades.

Key Things to Know

• Quality: At $42.99 for three, these are aftermarket blades, not OEM. They are likely made from hardened steel but may not hold an edge as long as factory blades.
• Installation: Moderate difficulty—requires a socket wrench, torque wrench (set to 70–90 ft-lbs), and possibly a blade removal tool. Always disconnect the spark plug and block the deck.
• Common gotchas: The blades may be slightly thinner than OEM, causing balance issues. Always balance them before installing. Also, verify the bolt size (usually 5/8-inch) matches your spindle.
• Lift: These blades have a moderate lift, good for dry grass but may clog in wet conditions. Not ideal for heavy mulching.

Should You Buy It

If you need a quick, affordable set of blades for a standard 46-inch Craftsman or Husqvarna deck and you’re comfortable with aftermarket parts, these are a solid choice. They’re not for heavy-duty commercial use or wet grass, but for regular residential mowing, the price and rating justify the purchase.
