John Deere L118 Belt Size FAQ
Is a close belt length good enough for the John Deere L118 deck?
The deck belt length found is 104 in (2,642 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
What is the risk with the John Deere L118 drive belt part number?
The captured drive belt number is GX20006. If the length and width are missing, a cheap cross-reference can still be wrong even when it claims to replace the OEM belt
Official information note
