8TEN LawnRAZOR Blade for Ariens Gravely Ikon X XD ZTX ZT XL 42 04794200 (Toothed Mulching) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade is a toothed mulching blade designed for select Ariens and Gravely zero-turn mowers with 42-inch decks. It replaces OEM part 04794200 and is sold as a 3-pack, intended for users who want finer grass clipping mulching rather than side discharge or bagging.

Fitment & Compatibility

• Deck size: 42-inch cutting deck only.
• Models: Ariens Ikon X, Ikon XD, ZTX, ZT XL series; Gravely ZT X, ZT XL, ZT XD series (verify your model’s deck part number).
• OEM replacement: Direct fit for Ariens/Gravely part 04794200.
• Measurements: Blade length is 18.5 inches (center hole to tip), center hole diameter 0.625 inches, blade thickness 0.1875 inches. Measure your existing blade to confirm.
• Check before buying: Confirm your deck is 42 inches and that your model uses the 04794200 OEM blade. Do not assume all 42-inch Ariens/Gravely decks use this blade—some use a different part number.

Key Things to Know

• Mulching performance: The toothed design cuts clippings finer than standard blades, reducing clumping, but may leave larger clumps in wet grass.
• Installation: Straightforward swap—use a torque wrench to 35-50 ft-lbs. The blades are pre-balanced, but you should still check balance on a balancer before mounting.
• Build quality: Some users report the blades are slightly thinner than OEM and may dull faster on sandy or rocky lawns. Inspect after each mowing season.
• No washer included: You’ll need to reuse your original mounting hardware or buy a new blade washer kit separately.

Should You Buy It

Buy this if you have a 42-inch Ariens or Gravely zero-turn and want to improve mulching quality without paying OEM prices. Skip it if you mow in consistently wet conditions or have a lot of debris—the toothed edge can dull quickly, and a standard lift blade may be more durable. The 3.5-star rating suggests decent value for the price, but not a premium upgrade.
