That's the first time I have ever heard that other ZTR manufacturers do not install wheel suspension options with the reason being Ferris owns the patent. With Hustler, Scag, Dixie Chopper.....and Bad Boy ZTR's having their own suspension offerings I find it hard to believe that Gravely couldn't design a suspension system that would not infringe on any patent Ferris may have. That's like saying Ford cannot implement a hybrid model car because Toyota holds the patent with the Prius. I tend to agree with user Ric that the reason others don't offer suspension systems is that it is more gimmick than it is functional. Besides, I would guess that the overall design of a ZTR mower lends itself to a better cut with a solid chassis and a floating deck. The BEST way to get a smoother ride on any brand ZTR is to get a good quality full suspension seat(that is after all the only area of a ZTR(the seat) that a operator would notice any difference in the ride.....NOT because the left front tire absorbs a bump. If most other components on the ZTR's you are comparing are similar I would demo them and make sure they have a full suspension seat if mowing for extended periods and ride is important. Like mentioned, dealer choice is as important as specs & price which won't vary much between brands(all of the ZTR's mentioned in this poll are very good machines).
