I have a CK4010. I know it's not a DK but to chime in on Kioti the brand, I have been very happy. I have had it for only about 2 years and the only problems I have had with it were self induced and doing things I shouldn't. I think that most folks that are not brand blind and know a thing or two about tractors feel that Kioti is a great brand. There are no glaring trends with maintenance just occasional issues that are even sometimes operator induced (although some owners are reluctant to admit it). Even though the dealer network is not as large as JD or Kubota, it is still a large network. Kioti, like Kubota builds all components on their tractors (with the exception of the largest class of tractors). I hope that this helps.
