Guys I am putting the 620 on my 12H and I need some good pictures of how the belt tightener assembly all goes together on it. I have the cast arm on the pulley shaft allready but I need to see where all the little flat strap pieces go and where they each bolt on. I had the pictures of it beforehand on my other computer but can't get them and Agcopartsbook doesn't show it clear enough to help. I have a 620 with the belt that goes forward to the thrower from the engine with the piece that attaches to the foot pedal instead of the style with the under tractor drive. Thanks for any help.
