John Deere LT180 Belt Size FAQ
Is a close belt length good enough for the John Deere LT180 deck?
The deck belt length found is 99 in (2,515 mm). Close is not the same as correct. A belt that is slightly short can overload bearings, while one slightly long can slip or fail to engage the blades cleanly
Why does 0.5 in (13 mm) belt width matter on the John Deere LT180?
The captured deck belt width is 0.5 in (13 mm). Pulley grooves are cut for a matching belt profile. Wrong width can cause squeal, heat, poor blade speed or fast belt wear
Why are there separate belt part numbers for the John Deere LT180?
The captured values separate the belt jobs: deck belt part number M150960 and drive belt part number M144044. Treat each number as position-specific and confirm it against the parts diagram before 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 John Deere parts catalog before ordering a replacement belt.
