Cub Cadet 1250 Belt Size FAQ
Why can the correct Cub Cadet 1250 drive belt still not pull properly?
The drive belt length found is 78 in (1,981 mm). If the tractor still slips, the belt may be routed wrong, the idler may be weak, or the pulley faces may be polished. Length alone does not fix a worn drive system
Why does 0.38 in (10 mm) belt width matter on the Cub Cadet 1250?
The captured drive belt width is 0.38 in (10 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
Mistakes do happen. Belt specs can change by year, mower deck, pulley layout, serial range and regional parts catalog. Please check the operator manual, belt routing decal, old belt label and official cubcadet.com before ordering a replacement belt.
