04771200 High Lift 52 Inch Mower Blades Compatible with ARIENS IKON XD 52 Blades, Gravely 52 Inch Mower Blades ZT X, ZT XL, Replace 00450300 03253800, 3 Pack

What It Is

The 04771200 High Lift 52 Inch Mower Blades are aftermarket replacement blades designed for Ariens Ikon XD 52 and Gravely ZT X/ZT XL zero-turn mowers with 52-inch decks. Their high-lift profile increases airflow for superior grass clipping discharge and bagging performance, making them ideal for thick or wet grass.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch cutting deck. These blades directly replace OEM part numbers 00450300 and 03253800. They fit Ariens Ikon XD 52 and Gravely ZT X, ZT XL models. Measure your existing blade: length should be 18 inches, center hole diameter 1 inch, and thickness 0.25 inches (approx. 6.35 mm). Check that your blade spindle pattern matches—these use a standard 5-point star center hole. Not compatible with 42-inch or 60-inch decks, or non-ZT models.

Key Things to Know

• Quality: Aftermarket blades; may not match OEM steel hardness or balance. Inspect for warping or burrs before installation.
• Installation: Use a torque wrench to tighten blade bolts to 70-90 ft-lbs. Left-hand threads on some spindles (check your manual). Always lift the deck and disconnect the spark plug.
• Gotchas: High-lift blades increase engine load and may reduce fuel efficiency. They can also throw debris further—keep bystanders clear.
• Pack: 3-pack covers a 3-blade deck. Verify your deck uses 3 blades (most 52-inch ZT models do).

Should You Buy It

Buy these if you need an affordable 3-pack of high-lift blades for a compatible Ariens or Gravely 52-inch zero-turn and prioritize bagging or discharge performance over OEM durability. Skip them if you mow in dusty or sandy conditions (high lift wears faster) or require precise factory balance.
