I have made my decision on which mower to buy. I was picking between the JD737 and the Ex Mark 52" 23hp Kaw. I am considering picking up the Ex Mark in the morning. It is obvious that for the most part, everyone likes the Ex Mark the best. I want to know of any known issues of the Ex Mark that I have not heard yet. I want to know of any bad experiences w/dealers or w/the manufacture. Any problems w/the mower, deck, or any thing else I should look out for. All the help is very appreciated.
