Grasscool Ikon XD 52 inch Mower Blades Replace Ariens 04771200 for Gravely ZT HD ZTX XL Apex Edge X XL 52" Zero Turn Mower

What It Is

This is a set of three 52-inch mower blades designed for zero-turn mowers. They are an aftermarket replacement for the Ariens 04771200 OEM blade set, intended for heavy-duty commercial or residential cutting on Gravely and Ariens 52-inch decks.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch cutting deck and uses three blades (not two or four). These blades are direct replacements for:

• OEM part: Ariens 04771200
• Fits models: Gravely ZT HD, ZTX, XL; Ariens Apex, Edge, Edge X, Edge XL (all 52" zero-turn models)

Measurements to verify:

• Overall length: 17.5 inches (center hole to tip)
• Center hole diameter: 15/16 inch (oval or round)
• Thickness: 0.203 inch (standard for high-lift blades)

Check your current blade’s part number or measure your blade length and hole size. These will NOT fit 48-inch or 60-inch decks.

Key Things to Know

• Quality: Grasscool blades are heat-treated and coated for rust resistance. They are comparable to OEM in thickness but may require balancing before install.
• Installation: Use a torque wrench to tighten to 70-80 ft-lbs. The blade bolt is reverse-threaded on some Gravely models—check your manual.
• Lift: These are high-lift blades, meaning they create more suction for bagging or mulching but may cause more wear in dusty conditions.
• Common gotcha: The center hole is slightly oval on some aftermarket sets. It will fit the spindle, but you may need to clean burrs with a file if tight.

Should You Buy It

If you own a Gravely or Ariens 52" zero-turn and want a budget-friendly alternative to OEM blades without sacrificing cut quality, these are a solid choice. They’re best for users who mow regularly and don’t mind minor prep (balancing). Avoid if you need a low-lift blade for sandy soil or if your deck uses a different spindle bolt pattern.
