John Deere 111 Belt Size FAQ
What should you watch when fitting a 104 in (2,642 mm) deck belt on the John Deere 111?
A 104 in (2,642 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 111 belt with the same length but different width?
The deck belt width found is 0.31 in (8 mm). That is a narrow belt, so do not casually swap in a 1/2-inch belt unless the parts diagram says it crosses over. Too-wide belts can ride high in the pulley. A belt with the wrong top width can ride too high or too low in the pulley even if the length looks right
Why are there separate belt part numbers for the John Deere 111?
The captured values separate the belt jobs: deck belt part number GY20072 and drive belt part number GX20006. Treat each number as position-specific and confirm it against the parts diagram before ordering
Is the captured John Deere 111 drive belt part number enough to buy from?
The captured drive belt number is GX20006. 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.
