04771200 Lawn Mower Blades 3 Pack, 18 Inch Blades for 52 Inch Deck, Zero Turn Mower Blades Replacement for Gravely ZT X ZT XL Ariens IKON X IKON XL

What It Is

This is a three-pack of 18-inch replacement blades designed for 52-inch zero-turn mowers. They fit Gravely ZT X/ZT XL and Ariens IKON X/IKON XL models, intended for residential or light commercial cutting.

Fitment & Compatibility

• Deck size: Must be 52 inches exactly—three 18-inch blades cover that width. Measure your current blade length end to end (hole center to tip) to confirm.
• Models: Gravely ZT X, ZT XL; Ariens IKON X, IKON XL. Check your model number (e.g., 915xxx) against the OEM part list. Not for older Gravely or Ariens models with different spindle spacing.
• OEM cross-reference: Replaces Gravely/Ariens part 04771200. If your mower uses a different OEM blade number (like 07200633 or 502053), these will not fit.
• Measurements: Center hole diameter is typically 5/8″ or 7/16″—verify yours. Blade thickness is 0.204″; if your spindle uses a thicker blade, these may wobble.

Key Things to Know

• Quality: Made from heat-treated carbon steel. Edge retention is decent for the price but not as durable as premium high-lift or mulching blades.
• Installation: Straightforward—remove old blades, clean spindle, install with washers and nut. Torque to 70-90 ft-lbs. Use anti-seize on bolts to prevent rust.
• Common gotcha: These are standard lift blades, not high-lift or mulching. If you bag grass frequently, you may need a different blade design for better airflow.
• Pack includes three blades only—no hardware (bolts, washers, nuts). Reuse existing hardware or buy a new set separately.

Should You Buy It

If you own a 52-inch Gravely ZT X/ZT XL or Ariens IKON X/IKON XL and need a budget-friendly, direct-fit replacement for regular cutting (not bagging or mulching), this three-pack is a solid value. For heavy commercial use or specialty cutting, spend more on OEM or premium blades.
