I honestly can't tell you what the ride difference may be with the Ferris at the SZ's much higher speed, no way to test. I do know the Ferris gives what I would consider the best ride of any mower in its class. When the Ferris dealer cut against my older SZ with his new Ferris 3100; I left him so far in the distance he was totally shocked. We crossed a small ditch and he made the statement, "I had no idea a SZ was that fast, and you never slowed down when crossing the ditch." I showed him the flex forks and explained I only had 8 lbs of air pressure in the front tires. The tires can react and absorb shock faster than any mechanical suspension. I can tell you something else that made the SZ look much faster than it actually was when comparing to the 3100. I can promise the dealer had not adjusted the stops on the new Ferris, they are shipped from the factory to run at a top speed of 10 mph, and it is up to the dealer to adjust the stops to let it achieve its advertised 12 mph. I have never understood the reasoning behind this, and most dealers seem unaware of this needed procedure. I talked with the manufacturer and was told they shipped their 3100 at 10 mph and it was up to the dealer or end user to adjust for top speed. I don't understand this reasoning and never will. I told the factory most people were unaware of this, and they stated it was in their information, and up to the dealer to make the change. I know a dealer one state over that sells Hustler, Scag, and Bad Boy, with the Bad Boy and Hustler SZ being advertised as 15 mph mowers, and the Cheetah at 16 mph. He told me they raced the mowers against one another on occasion, and that the SZ was always the fastest. In all honesty I would have thought the Cheetah to be faster. These advertised speeds are based on integrated components, in other words what the book claims the speed should be, not actual timed speed. I asked an engineer with Hustler if they ever pulled a SZ off the line and physically checked the speed and I was told no. I then asked him how they could advertise a hard number from something they never tested. That is when I was told they use calculations based on components to list speed. I've tried to get my hands on a Scag Cheetah to run it in a side by side comparison. The impression I've gotten is Scag does not want their Cheetah tested against a Hustler Super Z. They know I will state in writing exactly the how the mowers compare, if the Cheetah rides better and cuts faster, that is what I will state, if the opposite is true, that will be what is stated.
