8TEN LawnRAZOR Blade for Ariens Gravely Ikon-X Edge ZTX ZT-XL 52 52" Decks 04771200 (Toothed Mulching) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade (04771200) is a toothed mulching blade designed for 52" Ariens Gravely Ikon-X, Edge, ZTX, and ZT-XL zero-turn mowers. It’s built to chop clippings finer for better nutrient recycling, ideal for lawn care enthusiasts who want a clean, mulched finish without bagging.

Fitment & Compatibility

• Deck size: Fits only 52" decks—do not use on 48" or 60" models.
• OEM cross-reference: Replaces Ariens/Gravely part 04771200. Check your deck’s spindle pattern; these are 5-point star center holes.
• Measurements: Blade length is 18.5" (center to tip), width 2.5", thickness 0.2". Confirm your existing blade matches these dimensions.
• Model check: Compatible with Ikon-X, Edge, ZTX, ZT-XL series—but verify your specific serial number via Ariens/Gravely’s parts lookup to avoid spindle bolt differences.

Key Things to Know

• Quality: Heat-treated steel with a coating for rust resistance; holds edge well on grass but dulls faster on sandy or debris-heavy lawns.
• Installation: Easy swap with a socket wrench—torque spindle bolts to 70-80 ft-lbs. Use thread locker if bolts are reused.
• Common gotcha: The toothed edge can catch on thick wet grass if deck is too low; set cutting height to 2.5" or higher for best mulching.
• 3-pack value: Cheaper per blade than OEM singles, but you’ll need to sharpen more often—about every 10-15 hours of use.

Should You Buy It

Yes, if you own a 52" Ariens/Gravely zero-turn and want affordable, effective mulching without bagging. Avoid if you mow tall, wet, or debris-heavy grass—standard lift blades will perform better. For clean, dry lawns, this is a solid upgrade over OEM.
