Anyone bought one of these? I'm considering adding or trading in my super z with another mower. Been looking at the x-one and the only difference I can see is the wheel motors. I don't have any lawns that I can go 15+ mph and most likely will only put 1500 or so hours on a machine before I trade it. This all depends on when the "wear and tear" repairs begin. I don't like down time for repairs since I only run 1 mower now. If I had 2 my plan may change. Since there is such a price difference between the x-one and super z wonder if the x-one will hold up and last as well as teh super z. I'm not picky on mowers. I've run an exmark lazer hp and hustler super z and liked both equally well. I seem to compare more now to get the best value for my dollar.
