Not getting all your history, like age, usage, you original owner or prior owner habits. Winter time is hard on engines, even in Georgia or Texas. Condensation is a problem in that you have a lot of iron to get hot to get the oil hot to drive out condensation which is always there on cold days. If you continuously run your tractor for short intervals you will have a buildup of moisture and gray to chocolate oil depending upon the level of contamination.
As stated, pumping the throttle on a diesel is not like on a gas engine. What you are actually doing is changing the amount of fuel getting to the injectors. White smoke is water vapor; blue is oil, and black is dirty injectors/engine overloaded. Water in the winter is condensation from running the tractor for short periods and not giving it time to warm up and drive out the moisture. Happens all the time. Yes you are puking diesel by letting it run and not doing any work with it, but in the long term it is cheap insurance. I do and I am not on here complaining as you are. Get the point?
Before you jump to any conclusions, get your tractor out and put a piece of cardboard in front of the radiator thus blocking the air across it and allowing the coolant to get hot. Crank it up and pull the throttle to max. Let it run like that sitting stationary at WOT rpm for 30 minutes monitoring the engine temp while doing that. What you want is to have the engine temp get up to around midrange and stay there long enough to heat everything up and drive out the moisture. Obviously you don't want to red line it.
PS makes some good diesel additives that can help with winter operation. WW and tractor supply stores stock them along with other additive mfgrs. There are the users and the denyers. I am a user and no way would I be a denyer as additives have proven themselves time and time again to me. Buttttt additives can help combustion and fuel hygiene and all that, but condensation in the engine has to be burned out.
If you do what I said and come back the next day and still have problems, I'd be looking for water in the fuel. But I'm not there so I can't first hand help you to analyze your particular situation.
