I think you hit right on the head the turbo. Or, if you have an emergency stop check and see if it close. And last check the injector one bad one could cause lots of smoke out the stack. Good luck.

Don't forget to check the air filter (both outer and inner), plugged air filter will cause this. The turbo uses a waste gate, make sure the waste gate will move. The turbo on these Kubotas seldom fail unless there is some kind of lubrication problem (dirty, contaminated oil, or low oil pressure - low oil pressure will set a code). Waste gates have been know to stick especially on machines that do not get run very often.
