How do you install a John Deere F525 mower deck?

You have to first get the belt in place, but don't put it over the tightener. This is done easily enough if you slide the deck past all the connection points. Then allign the 2 main arms and pin them in, pin in the weight transfer cable, (connects to the left foot pedal,) and there is one additional connect on the back of the deck, a strange linkage deal. Then put the belt over the tightening pulley and engage it.
