8TEN LawnRAZOR Blade for Toro Z Master 5000 4000 6000 7000 Grandstand 60 HD HDX 140-1240 (Toothed Mulching) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade is a toothed mulching blade designed for Toro Z Master and Grandstand zero-turn mowers. It’s built to shred clippings finely for clean mulching and bagging on larger commercial or heavy-duty residential decks.

Fitment & Compatibility

Before buying, confirm your deck size and model. This 3-pack fits Toro Z Master 4000, 5000, 6000, and 7000 series, plus Grandstand 60 HD and HDX models with 60-inch decks. It replaces OEM part 140-1240. Measure your blade length (typically 20.5 inches), center hole (usually 5/8-inch), and thickness (0.25 inches). Check that your spindle pattern matches—these are for three-hole star or oval configurations. Not compatible with 48-inch or 52-inch decks or older Toro models without a 140-1240 fit.

Key Things to Know

• Quality: 8TEN blades are heat-treated, coated steel—durable but not OEM. Expect good mulching, but edge retention may be shorter than Toro factory blades.
• Installation: Easy with a socket wrench; no special tools needed. Torque to 80-100 ft-lbs. Use thread locker on spindle bolts if not already applied.
• Gotchas: The toothed design can create more drag, potentially reducing runtime on electric or small-engine mowers. Balance each blade before installing—unbalanced blades cause vibration. Check for deck clearance if you’ve added a mulch plug or bagger.
• Pack: Three blades for a 60-inch deck (two outer, one center). Verify your deck uses three blades—some 60-inch models use two.

Should You Buy It

Buy these if you need a budget-friendly mulching blade for a compatible Toro Z Master or Grandstand 60-inch deck and don’t mind slightly shorter edge life than OEM. They’re a solid value for high-volume mulching where fine clippings matter more than longevity.
