8TEN LawnRAZOR Mower Blade Set for Husqvarna Dixon MZT 52 inch Deck 539112079 510417801 539117911 10782 (High-Lift)

What It Is

The 8TEN LawnRAZOR Mower Blade Set is a high-lift aftermarket blade set designed for 52-inch Husqvarna and Dixon zero-turn mowers. Built for heavy cutting, mulching, and bagging, these blades excel in tall or damp grass where standard blades struggle.

Fitment & Compatibility

• Deck size: 52 inches (set of three blades)
• OEM part numbers: 539112079, 510417801, 539117911, 10782
• Models: Husqvarna MZT52 (all variants), Dixon ZTR 52-inch decks (check your model’s OEM part list)
• Measurements: Each blade is 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset. Verify your existing blade dimensions match exactly before purchase.
• Aftermarket note: These are not OEM Husqvarna blades; they’re manufactured by 8TEN. Fitment is generally identical, but tolerances can vary slightly—measure your current blade thickness (0.25 inches) to confirm.

Key Things to Know

• Installation difficulty: Moderate. Requires lifting the mower, removing three bolts (usually 15/16-inch or 5/8-inch), and torquing to 70-90 ft-lbs. Use a blade removal tool to avoid spinning.
• Common gotcha: High-lift blades create more airflow for bagging but increase engine load and noise. If your deck is prone to clogging in wet grass, these help; if you only side-discharge, standard lift may be better.
• Quality: 8TEN blades are heat-treated and coated for rust resistance, but some users report they dull faster than OEM in sandy soil. Inspect after 10-15 hours of use.
• Balance check: Always balance new blades before mounting. 8TEN sets are often balanced, but verify with a blade balancer to prevent vibration damage.

Should You Buy It

Buy this set if you need reliable high-lift performance for bagging or mulching on a Husqvarna or Dixon 52-inch zero-turn and want to save roughly 30% over OEM blades. Skip it if you primarily side-discharge in light conditions or prefer the longer lifespan of factory blades.
