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

What It Is

This is a set of three 18-inch replacement blades designed for 52-inch cutting decks on Ariens IKON X/IKON XL Edge and Gravely ZT X/ZT XL zero-turn mowers. They are for routine blade swaps to maintain clean cuts on residential or commercial turf.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 52" decks. Will not work on 48", 54", or 60" decks.
• Brand/model: Confirmed compatible with Ariens IKON X (2019+) and IKON XL Edge, plus Gravely ZT X and ZT XL. Not for older IKON or non-XL models.
• Measurements: Each blade is 18" long, 2-1/4" wide, with a 5/8" center hole. Measure your existing blade length and hole diameter—if they match, these will fit. The blades are non-OEM aftermarket, so check the spindle pattern (likely 2-hole, offset) matches your current blades.

Key Things to Know

• Quality vs OEM: Aftermarket blades may be slightly thinner or less balanced than Ariens/Gravely factory blades. Expect acceptable cut quality for residential use, but may dull faster on heavy or sandy grass.
• Installation: Straightforward bolt-on with a socket wrench. Torque bolts to 40–50 ft-lbs. Use a blade balancer after installation to avoid vibration.
• Common gotcha: The 2-1/4" width is narrower than some OEM blades (often 2-1/2"). This can reduce airflow and leave a less uniform cut in wet or tall grass. Check if your deck uses a wider blade before buying.
• Pack size: Three blades cover one 52" deck (typically uses 3 blades). No extras.

Should You Buy It

Buy these if you need a budget-friendly, quick swap for your Ariens or Gravely 52" zero-turn and don’t require OEM-grade longevity or perfect cut quality for commercial use. Avoid if you mow heavy, damp grass frequently or want maximum blade life—spend a few dollars more on factory blades.
