I'm looking at the possibility of getting a 2009 IS 1500 with a 21 HP Kawasaki with 290 hrs. It's in great shape but I'm more concerned about the machine as a whole and its performance. I have only 1.5 acres but I've been told by someone who has demo'd one that it left tufts of grass after the cut. Since I haven't tested one I'm looking for feedback.
