Traction has been my biggest limitation. I have a 48" and don't think I would go any wider. With the scarifiers down, I can cut a nice little wedge, but it is easy to stop the tractor with too much cut. Stop, raise it a bit, go forward, rinse, repeat. On the surface, a 60" seems like it would help production, but in the end, I don't think it will be as effective.
