I have a John Deere model 111 riding mower with a 28" cut. The drive tran (I believe that is what they call it) that powers the mower has slipped off.
1) How to I replace the belt (diagram ath lets me replace the belt)
2) The belt is old and probably needs replacement. What is the name/part number for this belt.
Thanks! Bill

Note that I should have said the drive train BELT has slipped off...

Here's the John Deer part look up:

I don't see a 28" deck in the list
the drive belt for the 30" is M82460
The drive belt for the 38" is M88184
