What It Is

This is a 6-pack of aftermarket 52-inch lawn mower blades designed for zero-turn mowers. They are compatible with Ariens IKON X, XL, and XD series, and Gravely ZT X and ZT XL series. Use them for regular blade replacements on 52-inch cutting decks.

Fitment & Compatibility

Before buying, verify three things:

• Deck size – These fit only 52-inch decks. Measure your deck or check the model sticker.
• Mounting pattern – Center hole diameter and bolt pattern must match your spindle. Measure your old blade’s center hole (typically 5/8” or 7/8”) and the distance between mounting holes.
• OEM cross-reference – They replace Ariens 00450300, 70716200, and Gravely 596-817. If your mower uses a different OEM number, measure your blade length (should be ~20.5 inches), width, and thickness.

Key Things to Know

• Quality – Aftermarket blades may be slightly thinner or less balanced than OEM. Check for warping or burrs before install.
• Installation – Use a torque wrench; tighten to 70-90 ft-lbs. Re-torque after 1 hour of use.
• Gotcha – These are sold as a 6-pack, but some 52-inch decks use 3 blades. You’ll have 3 spares.
• Performance – Expect similar cut quality to mid-tier OEM blades, but may dull faster in sandy or rocky soil.

Should You Buy It

If you own a 52-inch Ariens IKON or Gravely ZT series and want a budget-friendly 6-pack for multiple replacements, this is a solid choice. Skip if you need premium, long-life blades or have a different deck size.
