What It Is

A set of three high-lift 42-inch mower blades designed to replace OEM parts on Craftsman, Poulan Pro, Husqvarna, and AYP (American Yard Products) lawn tractors with 42-inch cutting decks. High-lift blades create stronger airflow for superior grass clipping discharge and bagging performance, ideal for thick or damp grass.

Fitment & Compatibility

• Deck size: Only for 42-inch cutting decks. Measure your deck width to confirm (blade length is approximately 21 inches each).
• Model compatibility: Fits Craftsman LT1000, LT2000, Poulan Pro, Husqvarna, and AYP tractors with a 42-inch stamped deck. Also replaces OEM part numbers 532138971, 138498, 138971, 532138498, and 138971X431.
• Center hole & spindle: Standard 5-point star center hole (common on AYP spindles). Check your spindle shape before buying—will not fit round-hole or other star patterns.
• Aftermarket vs OEM: These are aftermarket blades; they match OEM specs but may differ slightly in thickness or coating. Verify your existing blade’s length, hole pattern, and offset by comparing side-by-side.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and possibly a blade removal tool. Torque blade bolts to 70–90 ft-lbs.
• Lift & discharge: High-lift design increases bagging efficiency but may hurl debris farther. Not recommended for mulching without a conversion kit.
• Durability: Typically made of heat-treated steel; expect 1–2 seasons of normal use before sharpening or replacement.
• Gotchas: High-lift blades can strain the engine if grass is very wet or tall—avoid overloading the deck. Check blade balance after installation to prevent vibration.

Should You Buy It

Buy these if you own a 42-inch AYP-style Craftsman, Poulan Pro, or Husqvarna tractor and want better bagging or discharge performance than standard blades. They’re a budget-friendly, well-rated option that fits common models, but verify your spindle’s star pattern and blade length before purchase. Not ideal for mulching-only users.
