8TEN LawnRAZOR Blade Set 574870801 for Husqvarna 52 Inch Deck GT 52XLS GTH 27V52LS 26V52LS 3052TDF (High-Lift) 3 Pack

What It Is

This is a set of three high-lift replacement blades for 52-inch cutting decks, designed for Husqvarna zero-turn and lawn tractors. The high-lift profile increases airflow for superior grass discharge and bagging performance, making it ideal for thick or tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch deck and uses three blades. This set fits Husqvarna models including GT 52XLS, GTH 27V52LS, 26V52LS, and 3052TDF. The OEM part number is 574870801. Measure your current blade length (should be ~20.5 inches), center hole diameter (usually 1 inch), and drive pin/star pattern. Aftermarket blades may vary slightly in thickness or balance—compare with your original blade before installing.

Key Things to Know

• High-lift vs. standard: These blades create more lift and suction, which improves bagging and side discharge but may increase engine load and noise. Not ideal for mulching unless you swap to mulch plugs.
• Installation: Use a torque wrench (40-50 ft-lbs) and apply anti-seize to the center bolt. High-lift blades require the sharp edge to face the direction of rotation—double-check before tightening.
• Balance check: Aftermarket blades can be slightly off-balance out of the box. Use a blade balancer or a nail in the wall to check; file the heavy end lightly if needed.
• Deck compatibility: Only fits 52-inch decks with a three-blade spindle configuration. Will not work on 48-inch, 54-inch, or older Husqvarna decks with different blade mount patterns.

Should You Buy It

If you own a compatible Husqvarna 52-inch deck and prioritize clean cuts, bagging efficiency, or cutting tall grass, this is a solid, affordable upgrade over standard OEM blades. For mulching or very light-duty use, a standard or mulching blade may be a better fit.
