Cub Cadet 2518 Belt Size FAQ
What should you watch when fitting a 80 in (2,032 mm) deck belt on the Cub Cadet 2518?
A 80 in (2,032 mm) deck belt leaves little room for sloppy routing. This is a mid-length belt run, so routing and idler position still matter more than just matching a close-looking belt. Before blaming the new belt, compare the belt path to the routing decal and make sure it sits on the correct side of each keeper
Can you replace the Cub Cadet 2518 belt with the same length but different width?
The deck belt width found is 0.5 in (13 mm). That is the common 1/2-inch belt width range. Still match the OEM number because the belt angle, fabric wrap and effective length can differ. A belt with the wrong top width can ride too high or too low in the pulley even if the length looks right
Are the Cub Cadet 2518 deck and drive belt lengths close?
The deck belt is 80 in (2,032 mm) and the drive belt is 81 in (2,057 mm), about 1 in (25 mm) different. That is enough to treat them as separate belts when ordering
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.
