John Deere LX173 Belt Size FAQ
Is a close belt length good enough for the John Deere LX173 deck?
The deck belt length found is 66 in (1,676 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 LX173?
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
Are the John Deere LX173 deck and drive belt lengths close?
The deck belt is 66 in (1,676 mm) and the drive belt is 89 in (2,261 mm), about 23 in (584 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 John Deere parts catalog before ordering a replacement belt.
