I need to know the belt length for on my 620 thrower on my 12H. The Agco parts page lists the part number as 1035690M11. I have tried checking on the both of the pinned belt refernece pages on the board here as well as Googling the part number but to no avail. Anybody know the length I need? Near as I can figure it is about 64" long but thats just guestimating. Thanks for any help guys.
