John Deere LT155 Belt Size FAQ
What should you watch when fitting a 95 in (2,413 mm) deck belt on the John Deere LT155?
A 95 in (2,413 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 each.
Can you replace the John Deere LT155 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
How do you avoid mixing up the John Deere LT155 deck and drive belts?
Use the belt position first: deck belt part number M144202 and drive belt part number M126009. A deck belt number does not automatically fit the drive system, even when an aftermarket listing makes the cross-reference look close
Is the captured John Deere LT155 drive belt part number enough to buy from?
The captured drive belt number is M126009. That is useful for OEM lookup, but the drive belt length and width were not fully captured here. It is weak data for guessing an aftermarket belt by size alone
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.
