John Deere L105 Belt Size FAQ
Why can the correct John Deere L105 deck belt still slip?
The deck belt length found is 104 in (2,642 mm). Even with the right length, a weak idler spring, worn pulley groove or wrong belt path can make it slip. The part number and routing matter together
Why does 0.5 in (13 mm) belt width matter on the John Deere L105?
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 L105?
The captured values separate the belt jobs: deck belt part number M144202 and drive belt part number GX20006. 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.
