If your Cub Cadet zero-turn mower is slipping, squealing, or just won't move like it used to, chances are the transmission drive belt needs replacing. This is the genuine OEM Cub Cadet belt, part number 954-04043B. It replaces older numbers like 954-04043A, 954-04043, and some MTD versions too.
It fits a bunch of popular RZT models: RZT-17, RZT-22, RZT-42, RZT-50, and RZT-54. Always check your mower's manual or the old belt's number to be 100% sure. Swapping the belt is a pretty standard repair—you'll need to relieve tension, route the new belt exactly as the old one was, and retension. Having the right OEM belt ensures proper fit and performance, so your mower gets back to cutting clean and smooth. Don't let a worn belt ruin your lawn day!
