I have a john deere gt 262 lawn mower and am looking for a manual that shows the belt routing and how to replace. Is it free or do I have to pay for it.

Hi,
The manual is available for purchase from Deere, the fate of older machines. You can get the to the parts breakdown at JDParts, however.
I will add the link; if you want to "bookmark" you must do it on that first page. It will assume you are a dealer if you don't. Need a User Name and Password.
