I just had my local Hustler rep Ken Frye bring by a couple of Super Z mowers for me to Demo. One had the 28HP EFI the other was the regular 27HP Kohler with the colecction system on it. They are super fast well built mowers, that do a great job cutting grass. Ken was very informative, and was very happy to answer all my questions. I do have a few other mowers to demo before I make my final decission, but Hustler definitly gets a big thumbs up !
