I'm considering a new Hustler Super Z , or a used ZD-28 Kubota. Today the hustler rep brought by a demo for me to try out on my property, and I was very impressed with the cut, speed, and the hillside abilities, but the ride was a little rough even with the suspension seat. I have a pretty rough yard in several places, and it would really bounce me around at times. I guess the tire pressure could have been a little high, and caused some of the roughness, but I'm not sure. I will soon demo the ZD-28 Kubota at the owners property, but I won't be able to demo it on my property, because I don't have a way to transport it 45 miles just for a demo. If I buy it the owner would deliver it . In your opinion will the Kubota ride better or worse on rough terrain than the Super Z ? I know it longer, has a pivoting front axle, and it's also heavier.
