What It Is

This is a 57-inch replacement drive belt for zero-turn mowers, specifically designed for Ariens Ikon X and Ikon XD (42" and 52" decks) and Gravely ZTX 52 models. It transfers power from the engine to the hydrostatic transmissions, controlling forward/reverse movement.

Fitment & Compatibility

• Exact models: Ariens Ikon X 42" (915174, 915230, 915236), Ikon XD 52" (915250, 915256, 915257), Gravely ZTX 52 (915172). Check your mower’s model number (stamped under seat or on frame).
• OEM cross-reference: Replaces Ariens/Gravely part 07200718. If your original belt has this number, it’s a direct swap.
• Measurements: 57 inches outside length, 1/2 inch width. Measure your old belt end-to-end (unflexed) to confirm—variations in deck size or pulley wear can change fit.
• Deck size note: The 42" and 52" decks use the same drive belt length, but the 52" deck may have different pulley alignment. If your mower is 52", verify belt routing matches your model’s diagram.

Key Things to Know

• Aramid cord construction: Stronger than standard rubber belts, resists stretching and heat better—good for heavy-duty use.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt guard, then route around pulleys and tensioners. A belt tool or long screwdriver helps.
• Common gotcha: The belt must be routed behind the idler pulley on some models—check your mower’s manual or a routing diagram before finalizing.
• No OEM branding: This is an aftermarket belt, not an Ariens/Gravely original. Quality is high (4.3 stars from 12,782 reviews), but some users report slightly tighter fit than OEM—expect to adjust tension.

Should You Buy It

If you own an Ariens Ikon X, Ikon XD, or Gravely ZTX 52 and need a reliable, affordable drive belt replacement, this is a solid pick. The aramid cord adds durability over standard belts, and the price is about half of OEM. It’s not a perfect fit for every variant—double-check your model number and belt routing—but for most users, it’s a no-fuss upgrade that’ll get you mowing again.
