04771200 18" Lawn Mower Blades Replacement for 52" Deck, Width 2-1/4 inches, Center Hole 5/8 inches, Compatible with Ariens EDGE, IKON X, IKON XD and Gravely ZT X, ZT XL Zero Turn Mowers (3 Pack)

What It Is

This is a 3-pack of 18-inch replacement blades designed for 52-inch zero-turn mower decks. They fit specific Ariens and Gravely models, including the EDGE, IKON X, IKON XD, Gravely ZT X, and ZT XL series.

Fitment & Compatibility

Before buying, confirm these three measurements:

• Blade length: Exactly 18 inches (not 18.5 or 17.75).
• Width: 2-1/4 inches.
• Center hole: 5/8 inches (common on Ariens/Gravely spindles).

This is an aftermarket blade, not OEM Ariens (part 04771200) or Gravely. Check your deck model number—it must be a 52-inch deck. These will not fit 48-inch, 54-inch, or 60-inch decks. Also verify your mower’s spindle nut size (often 15/16″ or 1-1/8″) to ensure you have the right socket.

Key Things to Know

• Quality: Made from heat-treated carbon steel. Expect a reasonable lifespan, but may dull faster than OEM blades in heavy or sandy conditions.
• Installation: Straightforward if you have a jack or ramps. Torque spindle nuts to 70–90 ft-lbs. Reuse OEM washers/spacers if included.
• Balance: Out of the box, check blade balance with a simple balancer. Unbalanced blades cause vibration and wear spindles.
• Deck clearance: Ensure blade tips don’t hit the deck shell. Measure from spindle center to deck edge—must be at least 9 inches.

Should You Buy It

If you own a 52-inch Ariens EDGE, IKON X/XD, or Gravely ZT X/XL and want a budget-friendly 3-pack for routine blade swaps, this is a solid choice. It’s not for heavy commercial use or decks with odd spindle spacing. Verify your measurements first—fitment is narrow.
