I asked my dealer ( Rodicks Farm Machinery) last year about how many hours i should get out of my ck30 , he said i should get between 6-7 thousand... Hes been selling kioti for 22 years and has customers in the 8000 hour mark.. Hopefully with the new synthetics it will go well beyond that as well.. I also have a new dealer close to me now whos been selling Kioti for 2 years, he told me he has commercial customers putting a thousand hours a year on their machines.. I would say with proper care you should get a long life out of the Daedong Diesels.. The highway departments here in Albany are using the Kioits now for the past 2 years as well, they must be racking up some serious hours with all the mowing they do as well..
