I ran the IS 2000Z for a period of time this afternoon and was impressed with the ride and cut. This mower moved entirely too slow for my mowing conditions, but I expected that. The dealer is going to bring me a 3100Z in the morning, he seems to think it will compare more with the Super Z. I found this very interesting, I asked him to get on my mower an run it down a long straight stretch that has a small ditch to cross. The ground is a little rough in this entire area. He told me he had run Hustlers before, I told him to open my mower up and see if he noticed any difference. I saw him hit the ditch at top speed in both directions (going and coming). He drove back to where I was standing and said there is something different about this Hustler. He asked me what the difference was and I stood up on the flex fork and made it move up and down. I told him the seat made a big difference also, he said, "that is a standard Michigan seat that we don't really need with our suspension." I said, "look at this", I then sat down in the seat and made it rock back and forth like a rocking chair. I picked the seat up so he could look at the flex base, he then said, "I knew there was something different, because that ditch would have jarred me out of the seat. The rocking mechanism takes a great deal of shock away from your body." He told me the 3100Z would run as fast as my Super Z, we will put them side by side tomorrow and find out. Everyone including the Ferris factory told me the 2000 was the smoothest riding mower in their line-up, but this salesman told me the 3100 would ride better because of being heavier. I definitely believe the 3100 will have an exceptionally good ride as well as cut. I think I can understand why people like the Ferris suspension, the four wheels moving independently improves the ride dramatically. They do seem to be a little on the expensive side, but I could see people paying the price difference for a smooth ride. I mentioned Bad Boy mowers and the Ferris salesman told me they were on their last leg, and a relatively new mower company could not survive in this economy. I did not tell him when I talked with the factory last week they were behind 750 mowers on the assembly line that day. It truly amazes me at the way rumors travel. He was telling me they sold 40 to 50 Ferris mowers every year, which is honestly pretty good considering they are a John Deere dealer. He said they ruined the JD zero turn mowers. I said, "JD had a good cutting zero turn mower, what were they thinking with all the changes." He came right out with no hesitation and said, "they are crazy, JD has a bad habit of trying something new by letting the customers find the problems." JD is the only company with deep enough pockets to play that game.
