8TEN LawnRAZOR Mower Blade for Scag Ferris 48111 482879 1520842 Husqvarna 539101733 61 inch Deck (Toothed) 3 Pack

What It Is

The 8TEN LawnRAZOR toothed blade is a heavy-duty, 61-inch deck replacement blade designed for high-end commercial zero-turn mowers like Scag, Ferris, and Husqvarna. Its serrated edge excels at mulching and shredding tough grass, leaves, and light debris.

Fitment & Compatibility

• Deck size: Fits only 61-inch cutting decks (not 60 or 72-inch).
• OEM cross-references: Replaces Scag 48111, 482879, 1520842; Husqvarna 539101733; Ferris/Fox 5411574. Confirm your model uses a 5/8-inch center hole and 2.75-inch blade length from hole center to tip.
• Brands: Works on Scag Turf Tiger, Wildcat, Ferris IS3100Z/IS3200Z, and Husqvarna P-ZT61 series. Not compatible with most residential 42–54-inch decks.
• Check before buying: Measure your existing blade length and center hole size. Verify your spindle pattern (this is a 3-hole blade with 8.5-inch bolt circle). Do not assume fit based on brand alone—some 61-inch decks use different blade patterns.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a torque wrench and blade removal tool. Tighten to 70–90 ft-lbs. The toothed edge faces upward (toward the deck) on most models—double-check.
• Quality: 8TEN blades are 0.25-inch thick hardened steel, comparable to OEM Scag/Husqvarna. They balance well out of the box, but always check with a blade balancer.
• Gotcha: The toothed design creates more drag and noise than standard blades. It also dulls faster in sandy soil or rocky terrain. Expect to sharpen or replace every 15–25 hours of heavy use.
• 3-pack value: At ~$13 per blade, it’s roughly half the price of OEM. Good for commercial operators who rotate blades often.

Should You Buy It

If you own a 61-inch Scag, Ferris, or Husqvarna zero-turn and need aggressive mulching or leaf-shredding performance, this is a solid, budget-friendly alternative to OEM blades. Avoid it if you primarily bag or mow clean, manicured lawns—the toothed edge will leave a rougher cut.
