8TEN LawnRAZOR Mower Blade Set for Craftsman AYP 54 inch Deck 187254 Husqvarna 532187254 532187256 (Notched High Lift)

What It Is

The 8TEN LawnRAZOR Mower Blade Set is a set of three notched high-lift blades designed for 54-inch cutting decks on Craftsman and AYP (American Yard Products) riding mowers, as well as some Husqvarna models. These blades are built for heavy lifting and superior grass discharge, ideal for bagging or side-discharge in dense or tall grass.

Fitment & Compatibility

Before buying, verify your mower has a 54-inch deck—this set is specifically for that size. Compatible brands include Craftsman (models like 917.27 series), AYP, and Husqvarna (e.g., YTH24V54). Cross-reference with OEM part numbers 532187254 and 532187256. Measure your existing blades: each blade should be 20.5 inches long, with a 5-point star center hole and a 0.25-inch thickness. The notched design fits spindles that accept a center bolt (usually 5/16-24 thread). Check your deck’s spindle pattern—some older decks may require a different offset or hole shape. If your mower uses a different OEM number (e.g., 532187257), these won’t fit.

Key Things to Know

• Quality: 8TEN blades are heat-treated and coated for rust resistance, but they’re not as thick as OEM blades—expect slightly shorter life in rocky or sandy soil.
• Installation: Easy DIY swap with a socket and torque wrench (tighten to 70-90 ft-lbs). Use thread locker on the bolt to prevent loosening.
• Common Gotcha: The high-lift design creates more upward airflow, which can cause the deck to clog in wet grass or if the blades are dull. Sharpen after 10-15 hours of use.
• Balance: Blades come pre-balanced, but always check with a balancer before installing to avoid vibration.

Should You Buy It

Buy this if you have a 54-inch Craftsman or AYP mower and need a budget-friendly upgrade from standard blades for better bagging or side-discharge in tall grass. It’s a solid value for DIY homeowners, but skip it if you mow over rocks or debris often—opt for thicker OEM or mulching blades instead.
