Having been there and done that, I know exactly the feeling that you have experienced. The good part is that you were not injured. I was thrown from the tractor and landed in soft dirt. I not sure what hurt more.... my pride or my body. I was able to right my tractor with my Oliver OC3 and my F250 4x4. Mine was a 8000 pound Minneapolis Moline, so yours shouldn't present much of a problem to upright. Once you have it back on all 4's, the only problem that I can see is the oil might have leaked past the rings into the upper part of the cylinders. If this has happened and you try to start it, you might cause a hydraulic lock problem and bend a connecting rod. If it were mine, I would pull the injectors and then crank it over. No need to mention to check all fluids first, you already know that. Actually, I would drain and refill the crankcase. Measure the amount that comes out and that will give you a better idea of how much you lost. It will not take into consideration how much is on the ground. Also keep this accident to yourself, you don't want the state EPA coming in to do a environmental hazardous waste clean up. Just dig out the soil and hide it somewhere. Considering that you went over in soft ground, I doubt that there will be any lasting scars on the machine. If it is still under warranty, you might not want to clue in the selling dealer as to what happened. That way, if you have a problem down the road, he can't blame in on the accident. Any good diesel mechanic can give you advise and help on the engine situation and you don't have to consult with the dealer. Removing the injectors shouldn't cost very much. About 2 hours or less total to R&R them. If the batter has spilled acid, then neutralize it with baking soda. Since the battery is relatively new, I would add new electrolyte to replace what has spilled. Wash everything well with dish washing soap and water.
