Repairs Drive Belt - LX289

I am new to this forum and seeking information on the replacement of a Drive Belt on a John Deere LX289.
I have owned this Lawn Tractor since buying it new in 2004 and never had to replace the Drive Belt.

I have searched on line and U-Tube for description of the process but found nothing.
If any members have replaced a Drive Belt on a John Deere LX289 unit I would love to discuss the process.

Thanks
George
