Yes the machine will be a little tippy. Its a zero turn. I would highly recommend getting the weight kit. I think its 500lbs that bolts onto the back of the machine. I think it ends up hanging over about 3-4" so its not zero turn anymore but you will need it with the long arm. I too thought the machine was very tippy when I first got it coming from only using a conventional tail swing machine. But once I got used to it its really not bad at all.
I actually got into the show a day early and that is when I took most of these pictures. The show opens a day early for dealers and exhibitors, but I got in.
The show was very well attended in my opinion.
