I normally upgrade equipment every 2 yrs or 600hrs, this is the only reason I'm selling the Super Z. it is a 2003 Super Z w/27 Kohler 60" deck. 600+hrs on machine. I am mostly a solo operation so I have to take care of my equipment and this mower is no exception. Monthly oil change, yearly Hydro fluid and filter change, always greased weekly. This mower has the H/D canister airfilter, Quikchute OCDC, reciever hitch, anti blowout baffles, holds 13 gal of fuel, has the heat shield installed correcting the scorching issue. You can run double blades with no problem and can run many different blade combos as well. $6700.00 PM me with questions or for pics. I am near Nashville Tn.
