I like my Cub Cadet Zero Turn, except the rigid frame on uneven ground. I am currently exploring making the front axel pivot. The rigid frame is very dangerous and can cause the operator to loose control of the mower on uneven land. I don't understand why build a good piece of equipment and not do a pivotal front axel. I have operated a Dairy Farm for 46 years and all types of equipment for over 60 years. Without experience operating equipment the ordinary person would be subject to injury. As I have had my mower to loose traction and take off on it's own out of control several times. Luckily I have had a good landing spot. If you have any ideas on how to convert my mower to a pivot front axel please share with me.
