Cub Cadet RZT S42 Belt Size FAQ
Why can the correct Cub Cadet RZT S42 deck belt still slip?
The deck belt length found is 95 in (2,413 mm). Even with the right length, a weak idler spring, worn pulley groove or wrong belt path can make it slip. The part number and routing matter together
Why does 0.62 in (16 mm) belt width matter on the Cub Cadet RZT S42?
The captured deck belt width is 0.62 in (16 mm). Pulley grooves are cut for a matching belt profile. Wrong width can cause squeal, heat, poor blade speed or fast belt wear
Official information note
