The one thing I do have a problem with is you saying you have cut this same property on a previously owed ztr at 13 mph without seeing the bouncing you are experiencing with the Super Z. That my friend is not possible, my new longer wheel base Super Z would not ride smoothly over this ground, but much better than a shorter wheel base ztr equipped with only a suspension seat.
Think of this ground in terms of water you are riding across in a boat, the chop on water which has the peaks of its waves spaced out at a certain distance may be extremely rough riding in, lets say an 18' boat. You can take the same boat and add only 3' to its length making it a 21' boat, which in return will allow the boat to reach across, and stay on top of the waves making for a much smoother ride. The reason I use this illustration comes from many years of operating boats in size from 10' to 52'... the shorter, lighter boat will beat your brains out, while the heavier, longer boat gives a much superior ride. Weight and length is the part of the equation that makes basically anything ride better.
I just had a conversation with a dealer who sells alot of these and he said he has had a few complaints about the ride from guy's who own both the XR7 and new Super, he said the complaint came from guy's who own like 30 or 40 Super Z's so he took note.
It seems to be flex forks are the norm on these mowers and that was the cure he told me.
Puppy you are wrong about added weight helping the ride, it's your enemy and a stiffer more heavily built frame will add to it,and added weight on hills will cause the mower to slide down more not give more traction.
