I went to my dealers today and took a test run on the new M-72 37 hp Kawasaki Cub Tank. This is a 12 mph mower but at around 8 mph I could hardly stand the ride, I picked the deck up and it was still riding rougher than any mower I have ever operated. I got straight off the Tank and got on a new 15 mph Bobcat Predator Pro and the ride was much, much, much better, not even comparable. I did not like the feel of the controls on the Tank at all and the Bobcat was smooth as silk and so much easier to operate. If I even attempted to run the Tank the way I do my Hustler in a short period of time I would be looking for a spine surgeon. This is my formed opinion from what I experienced, does anyone have any idea what could make a mower ride this rough? The 37 Kawi is a very strong engine which I liked a lot.
