I know a few people had this problem with their 2520 but I can't seem to find the real fix except that there is a spring and 2 balls to replace.
1 Has anyone ever fixed this themselves?
2 What are the part numbers to from John Deere

Thank you jgayman I ordered the parts above through my local dealer with also parts #M800448 John Deere SEAL and
#CH14926 John Deere PACKING. (Numbers 1 and nine)
I'm hoping this is all I would need.
Has anyone installed these apparently upgraded springs? Any install tips?

Do you have the 2720 technical manual? If not, you may want to purchase one before attempting this repair. Looking at the photos it appears the front drive is accessed from inside the center case. It doesn't seem like you can do anything without splitting the tractor. Maybe someone who has actually done it will comment.

Yes, I purchased a tech manual shortly after I purchased the tractor.
I have to do my homework on it before I tear into it.

Not yet, seems every time I get ready to start I need the tractor to do some work.

No, it will pop out (disengage) out of 4 wd but not enough to turn the dashboard light off
I can disengage out of 4wd with no problem
