QWD 138971 Mower Blades 2 Pack for 42 Inch Deck, Replacement for 532138971 138498 127843 532127843, 5 Point Star High Lift Blades for Craftsman Husqvarna Poulan Riding Mowers

What It Is

The QWD 138971 2-pack is a set of aftermarket high-lift mower blades designed for 42-inch cutting decks on riding mowers. They replace OEM part numbers 532138971, 138498, 127843, and 532127843, and are intended for heavy-duty grass cutting and improved bagging or discharge performance.

Fitment & Compatibility

• Deck size: Only for 42-inch decks. Measure your deck width before buying.
• OEM cross-reference: Confirmed fit for Craftsman, Husqvarna, and Poulan riding mowers using the 138971/127843 pattern. Common models include Craftsman T1200, T1500, and Husqvarna YTH22V46.
• Blade dimensions: 20.5 inches long, 2.5 inches wide, 0.25 inches thick, with a 5-point star center hole (1-inch diameter). Measure your current blade’s length and center hole shape to verify.
• Brand note: Aftermarket, not OEM. Works as a direct replacement if your mower uses the star-pattern spindle mount. Check your spindle’s drive pin shape—some older models may use a different hole pattern.

Key Things to Know

• High-lift design increases airflow for better bagging and side discharge but may bog down in thick, wet grass. Not ideal for mulching without a conversion kit.
• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (set to 70-90 ft-lbs), and a blade removal tool or block of wood to prevent spinning. Always disconnect the spark plug first.
• Balance check: Aftermarket blades sometimes come unbalanced. Spin-test them on a blade balancer before installing to avoid vibration and spindle wear.
• Pack includes: Two blades only—no hardware. Reuse your existing bolts and washers, or buy new ones if worn.

Should You Buy It

Buy these if you need a budget-friendly, high-lift replacement for a 42-inch Craftsman, Husqvarna, or Poulan rider and prioritize bagging or discharge over mulching. They’re well-reviewed for fit and durability, but verify your spindle hole pattern first—star vs. oval can vary across models.
