What It Is

This is a 1/2-inch wide, 117-inch long replacement deck belt for 42-inch cutting decks on select Cub Cadet, Craftsman, Troy-Bilt, and Ultima zero-turn mowers. It drives the blades from the engine pulley to the deck spindles.

Fitment & Compatibility

Before buying, verify your mower model against the listed numbers: CMXGZAM501081, 490-501-C081, 490-501-M081, or 754P06134. This belt fits Cub Cadet ZT1-42, KH Z510, and Mustang Z42, plus Craftsman and Troy-Bilt equivalents with a 42-inch deck. Measure your old belt: it must be exactly 117 inches long and 1/2 inch wide. OEM part numbers include 754-06134 and 754P06134. Aftermarket versions may vary slightly in tension; check pulley alignment and belt routing diagram for your specific model before installation.

Key Things to Know

• Quality: OEM-spec construction with Kevlar cords for durability. Should last 2-3 seasons with normal residential use.
• Installation: Moderate difficulty. Requires removing the deck or belt guard, routing around pulleys per your mower’s diagram (often a serpentine pattern). A belt tensioner tool or breaker bar may be needed to release tension.
• Common gotcha: If your mower vibrates or blades stop engaging after replacement, you likely routed the belt incorrectly or missed a pulley. Double-check the diagram.
• Deck size: Only for 42-inch decks. Using on a different deck size will cause poor cutting or belt damage.

Should You Buy It

Yes, if you need a direct-fit, OEM-spec replacement for a 42-inch zero-turn deck from Cub Cadet, Craftsman, or Troy-Bilt. The price is fair for the build quality, and the high rating reflects reliable performance. Avoid it if your deck is a different size or your model isn’t listed—measure first.
