UDC Parts 07200523 Deck Belt Replacement for Ariens 42 Inch Ikon-X Ikon XD XL Zoom 42" Gravely ZT42 ZTX42 ZTXL42 / Aramid Cord / 130.00 inches

What It Is

This is a 130-inch aramid cord replacement deck belt for Ariens Ikon-X, Ikon XD, XL, and Zoom 42-inch zero-turn mowers, plus Gravely ZT42, ZTX42, and ZTXL42 models. It drives the blades from the engine pulley.

Fitment & Compatibility

Check your deck size – must be exactly 42 inches. Verify belt length – measure your old belt or confirm it’s 130.00 inches (some OEM belts are 129.5–130.5; this works for 130). Model list: Ariens Ikon-X (2017+), Ikon XD, XL 42, Zoom 42; Gravely ZT42, ZTX42, ZTXL42. OEM cross-references: Ariens 07200523, Gravely 07200523. Aftermarket note: UDC uses aramid cord instead of Kevlar; same performance, slightly lower price.

Key Things to Know

• Aramid cord is durable – resists stretching and heat better than standard rubber belts, good for heavy or wet grass.
• Installation is moderate – you’ll need to remove the deck belt shield, release the idler pulley tension, and route around three pulleys. No special tools, but check your owner’s manual for the diagram.
• Common gotcha – if blades don’t engage fully, the belt may be off a pulley or the idler arm is stuck. Also, inspect pulleys for rust or damage before replacing.
• 12,730 reviews with 4.3 stars – very popular; most users report good fit and long life.

Should You Buy It

Yes, if you have a 42-inch Ariens Ikon-X or Gravely ZT42/ZTX42 and want a reliable aftermarket belt that matches OEM specs at half the price. Skip it if you need a shorter or longer belt (e.g., 132-inch for some 42” decks) – measure first.
