I have begun looking for another ZTR for my lawn business and am looking mainly at the diesels because I like them. I presently have exmark 48" WB and an Everride warrior 60" ZTR both of which I might add are very good units. So far I have demoed the Kubota zd28 60", Exmark lazer xs w/31hp vanguard engine, and ferris IS4500 w/28hp cat 60". I would really like to demo the john deere 997 with 31hp yanmar but no one has one available. So far the exmark has proved to be the best plenty of power best clipping dispersal and awesome ride. If anyone has demoed any other diesels besides hustler I would like to here your thoughts. I used to have a hustler Super Z and it was the worst mower I personally have ever owned. I live in the north east where damp or wet cool grasses such as rye, blue, and fescue are my main grasses.
