Demoed a kubota ZD 326 this weekend on my 6 acre homestead. Have been using a kubota tractor for over 25 years. My yard is a good test track with less than smooth terrain, hills and trees. I was surprised how rough it rode compared to the tractor, like riding a brick. Are there better seats that help isolate this pounding. How does the Ferris suspension change the ride feel compared to all the other solid frames?
