We have a John Deere 6830 premium and some times when runing with some of load (not necessarly much) and going up in a slighty hill (also not much) which it should be capable of doing without problem. Sometimes it starts beeping and apears a message in the screen that says it laks of power and advices us to reduce speed and load. For example a case it have happened to me recently with the trailer with only 3 straw bales going up in bite of hil in the road it happened. When we start the tractor there is a bite of white smoke coming out of the exaust. And also when you turn of the tractor and after a few minutes you want to start it we can't or we have to try several times. We hace gone to the local mechanic and they doesn't know whats going on. Do you know what could be happening?
