    pj, I was looking through my SZ manual and saw that there was an extra idler pulley on the new 60" XR-7 decks where there is not one on the (54",66", and 72") XR-7 decks. Figures (4-18) and (4-19) in the manual. It would make since if there was maybe one on the 54" also, but I was just wondering if you knew why the extra pulley is only on the 60" deck.

    I don't know.
    But I will e-mail this post to the guys that designed the deck and see what they have to say.

    Here is the answer / explanation, direct from the guys that designed the deck.
    The extra idler is there because as the overlap between blades went from 1.25 to 0.75 the deck got shorter front to rear and the belt wrap around the pulleys got less. So we added another idler to increase the belt wrap to an acceptable degree.
