I have owned this mower for 20 months. It has 103.6hrs. The belt comes off frequently. I heard there was recall on the tensioner but I have not contacted the dealer about it yet. I had a control arm sensor come unmounted and I had to stick it back on. Where the control arms rub on the body, the cast aluminum arm is being worn away quite fast. The port side front wheel had some play in it so that every time I hit a small bump there was a metal-to-metal 'whack'. I had to install a spacer. I have the Kawasaki engine and it has performed well. I blow the engine off with a compressor after each use, and clean the underside of the mower deck. Store it inside at night and do not wash it with water. That's about all I know.
