8TEN LawnRAZOR Blade Set for Husqvarna GT54 YT54LS 54 Inch Deck 581101101 (Mulching) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade Set is a three-piece mulching blade replacement designed for Husqvarna 54-inch cutting decks, specifically for models like the GT54 and YT54LS. It uses OEM part number 581101101 and is intended to chop clippings finely for nutrient recycling, not for side discharge or bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch deck and is a Husqvarna GT54, YT54LS, or compatible model using OEM part 581101101. Check the blade length (typically around 20.5 inches), center hole size (usually 1 inch), and thickness (0.25 inches common for heavy-duty use). Cross-reference with your owner’s manual or existing blade measurements. This set is aftermarket, so verify it matches the OEM pattern—especially the offset and lift angle—for proper cutting and deck clearance. Not for 48-inch or 60-inch decks.

Key Things to Know

• Quality: 8TEN LawnRAZOR blades are heat-treated and coated for durability, but may be slightly thinner than OEM; check for warping after first use.
• Installation: Easy to install with basic tools (socket wrench, torque to ~50-60 ft-lbs); use thread locker and ensure blades are balanced to avoid vibration.
• Gotchas: Mulching blades require higher engine RPM and sharper grass for best results; may clog in wet or tall grass. Replace in sets of three to maintain deck balance.
• Performance: Users report fine mulching and less clumping than OEM, but some note reduced lift in thick grass compared to high-lift blades.

Should You Buy It

If you own a Husqvarna GT54 or YT54LS and want affordable, high-rated mulching blades for a 54-inch deck, this set is a solid buy—especially given the 4.9-star rating and clear compatibility. It’s ideal for frequent mulchers who prioritize fine clippings over bagging, but skip it if you need dedicated bagging or side-discharge performance.
