I'm supposed to start mowing 10acres in a few months and I already have a handful of account over 3 acres. I've been looking at a used 72" Exmark Z with a 27hp Daihtsu diesel, about 400 hrs on it. It's pretty rough for that kind of time. Anyone know about reliability on this model/engine? I could probably get that machine for under $5000. I'm also looking at an ex-golf course Toro 325D front mower 72" deck with a kubota diesel and over 3000hrs. The toro is in surprisingly good shape and the golf course was good about maintanence. From my experience you can't kill a kubota diesel regardless of hrs and this one starts quickly runs perfect and doesn't smoke. It seems much better built than a Z and is almost as maneuverable. The guy is asking just over $2000 for the Toro. Need to make a decision soon, please help!
