What It Is

This is a 1/2” x 117” V-belt designed for 42-inch zero-turn mower decks, specifically replacing OEM belts for Cub Cadet RZT models and compatible with Simplicity, Snapper, MTD, Craftsman, and Hustler machines. It drives the deck blades from the engine pulley.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and requires a 1/2” wide, 117” long belt. This belt replaces OEM numbers A115, Simplicity 1719911SM, Snapper 1719911SM, Cub Cadet 754-06134, 754P06134, 954-0197, and CMXGZAM501081. It fits many Cub Cadet RZT 42, RZT S 42, and RZT L 42 models, plus select MTD, Craftsman (ZTS 42), and Hustler (Raptor 42) zero-turns. Double-check your model number (e.g., 13APA1CT056) against the belt length—measure your old belt if possible. Aftermarket belt; not OEM, but matches OEM specs.

Key Things to Know

• Quality: Rated 4.5/5—users report good durability for residential use, but heavy commercial use may wear faster than OEM.
• Installation: Moderate difficulty. You’ll need to remove the deck, loosen tensioner pulley, and route belt per diagram (take a photo before removing old belt).
• Common gotcha: The belt must be exactly 117” – a fraction off can cause slipping or poor blade engagement. Measure old belt or check deck manual.
• Price: At $16.99, it’s about half the cost of OEM—good value for the performance.

Should You Buy It

Buy this if you need a reliable, budget-friendly replacement for a 42-inch zero-turn deck belt on a Cub Cadet RZT or compatible model, and you’re comfortable with a moderate DIY install. It’s not for commercial-grade use or odd-length decks—verify your belt length first.
