Sorry to hear of your problems with the new machine.
For a starting point, did you check to make sure everything was working before they loaded it onto your trailer?
And for clarity why did you buy in MD to ship to S. Carolina?
When speaking to the selling dealer I would ask that they cover you for expenses local to you to have a Kioti dealer, or other diesel tractor mechanic come to your place- or you transport to a local dealer to have your situation resolved to your satisfaction. The selling dealer installed your implements, and should have verified proper function prior to giving the machine to you for transport. Is there a possibility that the area in question was damaged when loaded onto the trailer? Even if the answer is yes, it would seem they are responsible for the problem and it's solution.
You deserve to have quick resolution to this without having to worry about possible damage to your new tractor.
What hydraulic fluid did you use to top off your system?
Good luck and hopefully a quick recovery to this issue.
Post back results, (and some clearer pics of the area in question), please.
Thanks, CM
