04771200 Lawn Mower Blades Replace Fits Gravely ZT X, ZT XL Series | Ariens IKON X, XL 52" Zero Turn Lawn Mower Blade for 52" Deck Zero Turn Mower Blades Replace 00450300 70716200, 3-Pack

What It Is

This 3-pack of 52-inch zero-turn mower blades replaces OEM part numbers 00450300 and 70716200. They are designed for Gravely ZT X and ZT XL series mowers, as well as Ariens IKON X and XL models with a 52-inch deck.

Fitment & Compatibility

Before buying, verify your mower has a 52-inch cutting deck—this set will not fit 42-inch, 48-inch, 60-inch, or other deck sizes. Confirm your model is one of these:

• Gravely ZT X, ZT XL (52" deck)
• Ariens IKON X, XL (52" deck)

Measure the blade length (should be 52-inch deck blades, typically ~20.5 inches each) and check the center hole diameter (usually 5/8-inch or 7/16-inch—measure yours to be sure). Also verify the blade thickness matches your OEM spec (often 0.1875-inch). If your deck uses a different blade pattern or offset, these may not fit.

Key Things to Buy

• Quality vs OEM: These are aftermarket blades. They may be slightly thinner or have a different edge grind than factory Gravely/Ariens blades, which can affect cut quality and longevity.
• Installation difficulty: Easy for most DIYers—jack up the mower safely, remove the blade bolt (use a block of wood to hold the blade), and swap. Torque bolts to 70–90 ft-lbs.
• Common gotchas: Always check blade orientation (cutting edge faces direction of rotation). Use a thread-locker on bolts. Replace all three blades at once to maintain balance.
• Price vs value: At $32.55 for three blades (about $10.85 each), this is significantly cheaper than OEM (often $25–$35 each). Expect shorter life if you mow heavy grass or debris.

Should You Buy It

Buy this set if you own a Gravely ZT X/XL or Ariens IKON X/XL with a 52-inch deck, are comfortable with basic blade replacement, and want a budget-friendly option for occasional mowing. Skip it if you need OEM-grade durability for commercial use or have a different deck size.
