The belt has come off my john deere tractor. (deck belt) , I need to find a diagram on how to put it back on correctly. I have looked on various sites and I am even more confused. It's a JD 655

Hi,
Number one, is it a Deere deck? Others make decks for this machine. Best thing you can doe is find the serial number tag and post that, deere will usually be 13 characters. Even deere makes a number of decks for the "55" series machines.
Peace,
Clarke
