Well, I took you advice and started test driving... Exmark was a little jerky, the Scag Tiger Cat 61" was much smoother but for the same price the Hustler Z4 was a nicer unit and the better ride. I certainly stepped up on my thinking after running around for a little while. I haven't ridden the Bad Boy yet but that is the next stop. I am certainly going up in price as well. Any advice on a Cub Cadet Commercial Tank 60?
