Hi, welcome to TBN and Kioti ownership. Congrats on your Kioti purchase too!
First thing would be to tell us is if you bought a new or used DK55, if it's a manual/shuttle shift or HST model, what year it was manufactured, etc. Is it a cab model or open station; if used how many hours on the clock. Did you trade something to buy it - if so what?
What do you plan to use it for primarily? Do you have any attachments, and if not what do you plan on getting?
We can also give you more info once we know more about what you have....
Do you have it yet? Can you post some pics?
For a detailed description try the Kioti.com website. Here is a link to the DK-55 open station model: DK55 Utility Tractor | Kioti Tractors
