superbobi 04771200 Lawn Mower Blades Replacement for ARIENS IKON X, XL, XD & Edge, Gravely ZT X & XL Series, Fit for 52" Deck Zero Turn Mower Blades Replace 00450300 70716200, 3-Pack

What It Is

This is a 3-pack of aftermarket replacement blades for 52" zero-turn mowers, specifically designed for ARIENS IKON X, XL, XD, and Edge models, as well as Gravely ZT X and XL series. These blades are meant to replace worn OEM blades to restore cutting performance.

Fitment & Compatibility

• Deck size must be exactly 52" – these blades will not fit 48", 54", or 60" decks.
• OEM cross-reference numbers: Replaces 00450300 and 70716200. Also supersedes 04771200.
• Blade dimensions: 21.25" length, 2.5" width, 0.25" thickness, with a 5-point star center hole (not a standard oval or diamond). Measure your current blade’s center hole shape before buying.
• Compatible models: ARIENS IKON X, XL, XD, Edge (2018+), Gravely ZT X, ZT XL (2018+). Double-check your model year – older or non-52" variants may not match.

Key Things to Know

• Aftermarket quality: These are hardened steel blades, but may be slightly thinner or lighter than OEM. Expect similar lifespan in residential use, but may dull faster in heavy commercial cutting.
• Installation difficulty: Easy – requires a socket wrench and blade removal tool. No special skills needed. Torque to 70-90 ft-lbs.
• Common gotcha: The 5-point star center hole is specific to ARIENS/Gravely 52" decks. These will not fit standard 5/8" or 7/8" round-hole spindles. If your old blade has a different hole shape, these won’t work.
• Sharpness: Blades come sharp but not razor-edged. Minor burrs are normal – a quick file touch-up is fine.

Should You Buy It

If you own a 52" ARIENS IKON X/XL/XD/Edge or Gravely ZT X/XL (2018 or newer) and want a budget-friendly 3-pack that matches OEM specs, this is a solid choice. Avoid if you have a different deck size, an older model with non-star center holes, or need commercial-grade durability for daily mowing.
