I have a 2010 exmark lazer z advantage series with a 60" deck and a 27 H.P kohler engine with 441 hours. Runs good with no known problems and still has some warranty. Mower was purchased 02/19/11. I am firm at 5825.00. If you have questions or are serious you can reach me at 727-992-4711. Scaling down the size of my business is the reason for sale. (West central Florida) I have a twin to it with 290 hours for 6100.00. hours will increase on this one as I still use it some.
