I am in the market for another mower this spring. I have Dixie Chopper Flatlanders now and for the most part like them pretty well. I am very curious as to how the Super Z mowers perform?? Is it a problem running double blades on a super z. Do they have enough power to mow at speed with doubles. Is there a OCDC for these machines?? I wanted some feed back from people who use them now. I am really concerned as to how well they stripe as well. My choices are either the XT 3000-60, XT2800-60, or the Super Z-60. I just do not want an under powered machine. I like to run doubles and mow fast. Having enough power really is important to me. If any one has pictures of some lawns striped using a hustler Z please post them.
