As BM said, if you are running pneumatic tires, lowering the pressure will help get rid of a lot of the bumpiness, especially on rough surfaces, but less so on harsh bumps like potholes or mismatched pavement slabs.
As I remember it, there are some adjustments possible on the shocks the 6x6 chairs use on the rear suspension, it MIGHT help to play with those, especially if you are light. I think there are settings for pre-load and damping, and if those are to high the ride will be bumpy as the suspension won't move when you hit a bump. OTOH if they are to soft the chair will tend to wallow, as it bounces around on the suspension, and will bottom out on big bumps. IOW you will probably have to play with it some to get it right, but having it right will help...
