John Deere 240 Belt Size FAQ
What should you watch when fitting a 95.5 in (2,426 mm) deck belt on the John Deere 240?
A 95.5 in (2,426 mm) deck belt leaves little room for sloppy routing. This is a longer mower belt run, so twist, idler alignment and the belt keeper positions matter. A belt can be the right length and still fail if it is routed wrong. Before blaming the new belt, compare the belt path to the routing decal and make sure it sits on the correct side of.
Can you replace the John Deere 240 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 John Deere 240 deck and drive belt lengths close?
The deck belt is 95.5 in (2,426 mm) and the drive belt is 74 in (1,880 mm), about 21.5 in (546 mm) different. That is enough to treat them as separate belts when ordering
Why does the John Deere 240 deck size matter before buying a belt?
The deck size captured is 48 in deck. That matters because the same tractor model can use different belt routing on different decks. Match the 48 in deck deck before relying on 95.5 in (2,426 mm)
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 John Deere parts catalog before ordering a replacement belt.
