I just got a 95 model dixie. IT CUTS GREAT. My question: As it is set up right now, the deck, at its highest point, is cutting about 3.75 to 4 inches. So I've only been able to lower it one or two at the most notches (on the wratchet foot lever). Tomorrow I am cutting fescue. How do I adjust the deck set up so that I can mow from say 4.5 inches and down instead of what I described above. And, how do I keep my pitch correct? THank you very much.
