8TEN LawnRAZOR Blade Set for AYP Husqvarna Poulan 54 inch Deck 187256 187254 574292401 532187254 (Notched High Lift)

What It Is

The 8TEN LawnRAZOR Blade Set is a set of three notched high-lift blades designed for 54-inch cutting decks on select AYP/Husqvarna/Poulan lawn tractors. These blades create increased airflow for superior grass lift and bagging performance, making them ideal for mulching or collecting clippings in thick or damp grass.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 54 inches and that your mower uses three blades. These blades replace OEM part numbers 187256, 187254, 574292401, and 532187254. They fit most AYP-built models including Husqvarna, Poulan Pro, Craftsman, and McCulloch tractors from the 2000s onward. Measure your existing blade length (should be roughly 20.5 inches), center hole diameter (typically 7/8-inch or 1-inch), and notch pattern—this set uses a notched design for center bolt clearance. Check your owner’s manual or current blade part number for compatibility if unsure.

Key Things to Buy

• Quality: Made from heat-treated carbon steel with a protective coating; many users report they last as long as OEM blades despite the lower price.
• Installation: Straightforward swap—use a socket wrench to remove the center bolt. No special tools required, but a torque wrench is recommended (tighten to 70-90 ft-lbs).
• Gotcha: The high-lift design creates more drag, which may slightly reduce engine RPM or fuel efficiency on older or lower-horsepower tractors.
• Gotcha: Ensure the notch aligns with your spindle’s bolt head; if your deck uses a different bolt pattern, these won’t fit.

Should You Buy It

If you own a 54-inch AYP/Husqvarna/Poulan tractor and want reliable, sharp blades that improve bagging and mulching without paying OEM prices, this set is a solid choice. It’s best for homeowners who mow frequently and need consistent lift in varied grass conditions.
