OK, so my son who is more mechanically inclined then most his age, took apart our snapper mower model 21335p to change the belt and left it for a couple weeks ago. Well he forgot how it goes back together. If someone has a picture I could look. It would be great. There is a pully left over.lol.. A close up rear view over the area where the belts and pullies are I think would work. Hope he learned his lesson this time.
