138971 42 inch 5-Star Blades for Craftsman LT1000 LT2000 YT3000 T110 Husqvarna YTH22V42 YTH18542 YTA18542 Poulan 42'' Deck Cut Lawn Tractor Zero-Turn Mower 127843 532138971 (Medium Lift) 2-Pack, Black

What It Is

This 2-pack of 42-inch 5-Star medium-lift blades is designed for 42-inch cutting decks on Craftsman, Husqvarna, and Poulan lawn tractors and zero-turn mowers. They replace OEM part 532138971 and are built for regular mulching and bagging on mid-sized residential yards.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches (measured blade tip to tip). These fit Craftsman LT1000, LT2000, YT3000, T110; Husqvarna YTH22V42, YTH18542, YTA18542; and Poulan 42-inch deck models. They are aftermarket replacements for OEM 127843 and 532138971. Check your spindle hole size—these use a standard 5-point star center hole. Measure your existing blade length and center hole shape to avoid returns. Not for 46-inch or 54-inch decks.

Key Things to Know

• Medium lift: Good for mulching and bagging, but less aggressive than high-lift blades—avoid for heavy wet grass or leaf collection.
• Installation: Easy bolt-on with a socket wrench; torque to 40-50 ft-lbs. Use thread locker if bolts are loose.
• Quality: Black powder coating resists rust, but edges dull faster than OEM premium blades. Check balance before installing.
• Gotcha: The 5-star center hole is specific—won’t fit round or oval hole spindles. Verify your spindle matches before ordering.

Should You Buy It

If you have a 42-inch Craftsman, Husqvarna, or Poulan tractor with a 5-star spindle and need a budget-friendly blade for regular mulching and bagging, this 2-pack is a solid value. Skip it if you cut heavy grass, need high-lift performance, or have a different deck size.
