I had a cub 60" mower that I got in a trade with another cub owner. I thought that it would be just the ticket as I really like to use the 3 pt hitch and do not like to hook up a belly mower.
Used it behind my 5254. What a nightmare. If you used it on any kind of a hill, it would try to swing the tractor around and tip it over. I also had to install the front weight bracket and 8 weights to be able to pick the mower up off the ground.
This was one of my reasons for upgrading to the sc2400. I know have the 60" belly mower and really like it. The new mower is a lot easier to remove and put back on.
Be sure to checkout how much the rear mower will weigh.
Hope this helps, and good luck.
