I need a routing diagram for my Scotts riding lawnmower by John Deere; it is a 17.5 hp 42 in cut with one belt for the platform and one belt for the drive.

Hi,
Try my hompage to see what is available at:
OPE by Crigby (http://opebycrigby.tripod.com/)
Or:
http://opebycrigby.tripod.com/decks/jdpdf/scottsdeckbelt.pdf
For the how-to bulletin on the deck and the motion drive belt page:
John Deere motion drive by crigby (http://opebycrigby.tripod.com/drive/jddrive.html)
And use the scroll donwn to the Sabre models.
Peace.
Clarke
PS The homepage link is also in my sig.
