My X590 has only 15 hours on it. I did the necessary oil and filter change at 8 hours. It has been used only for light mowing...grass, no hard stuff. Never mowed when turf was wet. Has always had a Battery Tender attached when not in use. Is stored in dry garage under a breathable cover. Has been thoroughly cleaned after every use. The blades have never hit any rocks or hard objects and are still sharp. Have always used stabilized gas. Will be greased at end of season...late October. I would prefer not having to have my dealer pick it up to do an annual service. I have two very nice Harley Davidsons that each see only about 1000 highway miles per year. I have them serviced by the dealer every other year. I have found this to be very satisfactory. Would this probably be sufficient for the Deere X590.
