I am looking to buy a new mower, but would like to hear some opinions from those of you that do this for a living and know this stuff. Let me start by saying...I will be mowing approximately 3.5 acres. There are quite a few obstacles, so I think I am leaning toward a ZTR mower. There are some slopes, but nothing too steep. Also, the area is rocky, and I'm sure I will hit a few rocks from time to time, so I want something that will hold up. From what I have heard from others thusfar, I am leaning toward a Hustler FasTrak mower with a 52' deck. It comes with either a Honda or Kohler engine in 18 or 20 hp. I know this is a residential mower, not commercial, but again, I am not doing this for a living. What are your thoughts on this mower and these engines? Also, feel free to recommend others you think would be suitable to the task. I am looking to spend between $5,000 and $7,000. Thanks in advance.
