I am going to buy a ZTR within the next 3 weeks. I've narrowed down my search to buying a Hustler. But I am trying to determine if it is worth spending the extra to get the Super Z over the Z. I am a residential owner with 6.25 acres of somewhat flat, somewhat rough terain. No house or struture yet on the property, but will over the next 3 years. Plan on building a walk out so I will be building in some hills and such. Please let me know if the Super Z is over kill or not. I only want to buy one mower to last me years and want the least amount of problems as possible. Any input is welcome.
