I have an older craftsman riding mower and I need to replace the belt. I need a diagram to do this. It is a 8hp. 4speed with a 30 inch deck.

Hi,
This a rear engine rider. Look for the model number tag; I need to know the first three digits. 917, 502, etc.
Sounds as if it is old enough to have been made by any one of a few manufacturers.
Peace,
Clarke
