04771200 Lawn Mower Blades for 52" Deck - Fits Gravely ZT X ZT XL, Ariens IKON X XL XD & Edge Zero Turn Mowers, Replace OEM 04771200 00450300 70716200

What It Is

This is a set of three replacement blades for 52-inch cutting decks on Gravely ZT X and ZT XL series zero-turn mowers, as well as Ariens IKON X, XL, XD, and Edge models. Designed for medium-to-heavy residential mowing and light commercial use.

Fitment & Compatibility

• Deck size must be exactly 52 inches – measure your deck before ordering. These blades will not fit 48", 54", or 60" decks.
• Direct OEM replacements for Gravely/Ariens part numbers 04771200, 00450300, and 70716200. Cross-check your current blade’s part number.
• Blade dimensions: 18.5 inches long, 2.5 inches wide, 0.203 inches thick, with a 1-inch center hole and a 7/16-inch offset. Measure your old blade to confirm.
• Fits models including: Gravely ZT X 52, ZT XL 52; Ariens IKON X 52, IKON XL 52, IKON XD 52, Edge 52. Verify your specific model year on the manufacturer’s site.
• Aftermarket set – not OEM, but matches OEM specs. Check that blade thickness and hole alignment match your spindle assembly.

Key Things to Know

• Installation difficulty: Easy – requires a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque to 70–90 ft-lbs.
• Quality: High-carbon steel with a hardened edge. Reviews note good balance and sharpness out of the box, but some report uneven wear after heavy use.
• Common gotcha: These blades are “high-lift” – they produce strong airflow for bagging but may cause more dust/debris in dry conditions. Not ideal for mulching without a kit.
• Lift angle: 30-degree lift. If your deck has a different angle, mulching or discharge performance may suffer.

Should You Buy It

Yes, if you own a 52-inch Gravely ZT X/XL or Ariens IKON/Edge and need a budget-friendly, drop-in replacement. Avoid if you need OEM-specific blade balance for commercial use or prefer a mulching blade design. For residential mowing and occasional bagging, this is a solid value at $36.59.
