04771200 Lawn Mower Blade Replace for Ariens IKON X, IKON XL Fit for Gravely 52" Deck Mowers ZT X ZT XL, Replace 00450300 70716200 Mower Blades, 3 Pack

What It Is

This is a 3-pack of aftermarket 52-inch deck blades designed for Ariens IKON X/XL and Gravely ZT X/ZT XL zero-turn mowers. Each blade measures 20.5 inches long with a 1-inch center hole and 3/4-inch offset, intended for standard mulching or bagging on residential/commercial mowers.

Fitment & Compatibility

Before buying, verify these specifics:

• Deck size: Only fits 52-inch decks. Measure your deck width—this will not work on 48" or 60" decks.
• Model check: Compatible with Ariens IKON X (model 915150, 915151) and IKON XL (model 915153, 915154). For Gravely, fits ZT X (model 991082, 991083) and ZT XL (model 991084, 991085).
• OEM cross-reference: Replaces Ariens/Gravely part numbers 00450300 and 70716200. Confirm your original blade part number matches one of these.
• Physical dimensions: Blade length 20.5", center hole 1", offset 0.75". Measure your old blade to confirm.
• Not for: Any deck under 52", or older Ariens/Gravely models (e.g., IKON 42" or ZT HD series).

Key Things to Know

• Quality: These are aftermarket stamped steel blades, not OEM. Expect similar durability for residential use, but may wear faster under heavy commercial mowing.
• Installation: Straightforward bolt-on replacement. Use a torque wrench (50-60 ft-lbs) and replace blade bolts if worn. No special tools needed beyond a socket and safety block.
• Common gotcha: Check blade orientation—the lift wing must face upward toward the deck. Installing upside down causes poor cut and vibration.
• Balance: Aftermarket blades sometimes require balancing before use. Use a blade balancer; if one side dips, file the heavy end slightly.

Should You Buy It

If you own a 52-inch Ariens IKON X/XL or Gravely ZT X/XL and need a budget-friendly 3-pack for regular mulching or bagging, this is a solid value at ~$10 per blade. Skip it if you’re a commercial user demanding maximum lifespan, or if you need OEM precision for a perfect cut on delicate turf. For most homeowners, it delivers reliable performance at half the OEM price.
