Kubota Diesel Zero Turn Overheating - HELP

Posted by RTR on July 26, 2018 at 07:39:24 from (107.77.68.21):

We have this Kunitz diesel mower model ZD-21 that will overheat after approximately 15 minutes of use. I arrived to the site to inspect it and upon arrival it appeared to be empty of coolant in radiator and overflow bottle. We didn’t have coolant on site so I filled it with water (a little too much). They ran the machine after we left and said it overheated again. I found it in the shed this morning and it appeared empty in radiator and overflow tank again!!! I filled with water and told supervisor to run it while I went to bathroom. When I came out She said it shut down on her, was blowing black smoke and was overheated. I went immediately to look for leaks and only found it blew water out the overflow tube but no leaks anywhere else. Was definitely overheated and overflow bottle water level was higher and it was burping. Oil was also leaking out of the filler on the top of valve cover. Oil level in engine is perfect.

At a loss. What’s wrong!?!? Thermostat? Stopped up radiator? Head gasket?
