Kubota L2250DT
I just purchased a Kubota B1750HST with 1250 hr. I noticed that the oil is over full,so I took and oil sample and it came back that there was water in the oil. No antifreeze the anti freeze in the radiator is full and green. he ran the test twice to make sure but it came back just water.does anyone know where it might be coming from?

Did it sit a long time? Possible there was heavy condensation that got inside the oil pan for some reason?

It didn't look like it was pressure wash. The motor is pretty dirty still. The air cleaner is missing the cover that goes over the front of the filter.

I am not sure I bought it from a car dealer. It is a 1992 and only have 1250,so I don't think it was used a lot. Has a trailer ball mounted to the bucket and the back blade. So I wonder if it was used at some kind of a boat storage place. If that's the case than it was probably only use for short periods of time.

get the oil changed, run it, but watch it close. My last tractor had about a inch of extra oil on the dip stick when I bought it. All sorts of stuff was running through my mind. Changed oil and filter and it does not use or add any oil between changes. Water runs down the steering column and freezes. Water will also travel down the gear shift and end up in the gear case, but you have HST, . Kubota has a good rep on their motors. Google it but no problems come to mind. Car Dealer may be the problem.

I think I would change the oil and filter and then monitor the oil and coolant closely. IF the oil level increases or the coolant decreases then look at a possible head gasket problem.

Used car dealers have been known to top up all fluids and run engines a little to make it look like they are good.

Being you are in cold country and it is winter, could it just be condensation showing up. Machine left idling a while, setting outside maybe in the rain with the oil stick not quite seated in horizontal rain or snow or washing. **** some of the old 327 Chevys I used to have grew a whitish beard on the oil breather in the winter. No big deal I would think. Just fill it againon a nice and level surface and full to the top of the oil mark on the stick then run it a while.
Honestly I would think if you had enough water to make it raise enough to notice on the stick it would look like a milkshake. Good old innards of a Milky Way candy bar. If it's just oil looking like oil there cant be all that much water in there. Since you didn't change the oil initially you don't know how much the mechanic dumped in there. Also, how many engines take EXACT quarts? Not many and how many mechanics are all that fussy about how perfect they get those levels? You know, toss in the rest of the bottle and get on to the next job. Keep an eye on it and I'll bet you will find out it was nothing.;)

The situation you described is very common in the Marine industry and it is referred to as the engine "Making Oil". In reality it is not making oil but picking up moisture over time and it gets worse the longer the engine goes without running and the higher the humidity is in your area. The enemy of combustion engines is moisture and running the engine on a regular basis is the best long term cure for preventing the making oil problem. You could run the engine for a while and the moisture will gradually go away, but the water also degrades the quality of your oil and its lubricity, so I would change the oil and your oil filter; another place that gathers water and moisture, and run the engine for a while to see if the oil level remains constant. If it does not, then you have other problems.
The person or persons who sold you the Kubota should have changed the oil and the filter before they sold it to you if it had set a long time. If you have further problems I would go back to them and explain that the oil had water in it. I would also check and probably replace any hydraulic fluids and filters if you decide to keep it. I would also take a look at your fuel filter, another place that gathers water and gunk when the engine is not run for a long time.

Noting your comment that the tractor history involved a "boat place" perhaps it was driven into the water too far.
I never go deeper than the lower part of the rim, I.e about 8" of water depth. Waves can suddenly increase the water depth and who know where it could get int the crankcase.
I agree with other who suggest draining and watching after refilling.
Just cracking the drain plug after the tractor has been sitting will reveal any water in the crankcase as it sits on the bottom of the engine.
