How do I replace the belt on a John Deere GX 75 Mower? (belt not broken)

Hi,
Well, I tried several ways to get this info to you! I could not get it to convert to a pdf, and I could not get it to "zip" small enough because of 2 dozen pictures. So I simply put up a site on Tripod and put it there. Brand new, less than an hour old as I write. Just use the File, Save As.. menu options, or print. Could only find the GX/SX85 machines, but the difference is Kawasaki versus Briggs engines.
