8TEN LawnRAZOR Mower Blade Set for AYP Husqvarna Poulan LT125 38 inch Deck 143978 532143978 532121263 (High-Lift)

What It Is

The 8TEN LawnRAZOR High-Lift Mower Blade Set is an aftermarket replacement designed for 38-inch cutting decks on AYP (American Yard Products) tractors, including Husqvarna, Poulan, and Craftsman models. Its high-lift design increases airflow for superior grass discharge and bagging performance in mulching or side-discharge setups.

Fitment & Compatibility

Before buying, verify these three points:

• Deck size: Fits only 38-inch decks – measure your deck width to confirm.
• Model compatibility: Works with AYP/Husqvarna/Poulan models like LT125, LT155, and similar. Cross-references OEM part numbers 143978, 532143978, and 532121263.
• Blade dimensions: Each blade is 18.5 inches long, with a 1-inch center hole and a 0.5-inch offset. Ensure your spindle pattern matches (typically 5-point star or oval).
• Aftermarket note: Not OEM, but meets or exceeds OEM specs. Check your owner’s manual for exact blade length and hole size to avoid fitment issues.

Key Things to Know

• High-lift performance: Excellent for bagging and wet grass, but may require more engine power and can leave a rougher cut in dry, sparse conditions.
• Installation difficulty: Easy for DIYers – just remove the old blade, install with the lift side up, and torque to 30-40 ft-lbs. Use a blade removal tool for safety.
• Common gotcha: These blades are sharp and balanced out of the box, but always re-check balance before installation to prevent vibration and spindle wear.
• Durability: Heat-treated steel with a corrosion-resistant coating – lasts a full season under normal use, but avoid hitting rocks or roots.

Should You Buy It

Yes, if you own a 38-inch AYP/Husqvarna/Poulan tractor and prioritize bagging or thick grass cutting. The high-lift design boosts discharge, but skip it if you mainly mulch or cut dry lawns (a standard or mulching blade would be smoother). At $33.95 with a 4.8-star rating, it’s a solid value for the performance.
