Well by luck or not I was behind because of a rain out and I called my dealer to see if he had any demos. A Ferris IS3000 came in and he let me use it for a couple days. I am a Walker operator in real life but man was I impressed by the suspension of the Ferris. The mower i had was a 25HP Kawi which isn't my first choice but it was what the demo came with. I can say that the suspension system is UNREAL. It works as advertised. I have some very rough lawns that beat me to death on a Walker and this mower sailed over them. We had tremendous growth because of alot of rain and the mower did a nice job of cutting. For an all out production mower this thing did fine by me. It also climbed hills like a goat. It did better than the Walker on some of my challenging properties. I have it for another day (Friday) and this is the big test. Steep riverside hills. I am still going to demo the Exmark and the Hustler within the next few weeks but so far this guy is a tough competitor. I know it beats the heck out of a Scag and a Yazoo/Kees in all respects.
