I need the deck belt diagram for a cub cadet model#3205 tractor with a 60" deck model# 190-291-100.

Hi,
I am really beginning to like the people at the end of this link. If they do business half as well as they maintain their reference sites, they are awesome. At any rate they have 3 great sites for info including the parts breakdown on your deck.

And I got to looking at it and it is as bad as and old Deere breakdown, shows enough belt to give it a part number. I will put up another gearbox/driveshaft deck picture for reference, also
Peace,
Clarke
