I have owned different types of garden equipment and I have to say the best one I have found is the John Deere GT-245. This is my second one I have owned and nothing else that I have had matches up to it. I have owned Cub Cadet GT2544 and a John Deere GT275.
My in-laws had purchased JD and I didn't want to follow suit with them but after owning a JD GT245 the power of a 20hp Kaw. motor and 54" mowing deck and the quality the GT245 has I feel that for a older tractor that is the one to beat.
