If it has been sitting that long in a metal shed with little or no running,what you are seeing is condensation. A thorough draining of all compartments should clean it up.You can use a "clean up filter" for the hydraulics after draining any condensation. I would prelube the engine by pumping a quart of clean motor oil into the engine where the oil sender threads in and finish filling the engine. Get it running and up to temperature for a good hour or so, drain the oil and change the filter and fill it with break in oil and run it for at least 50 hours under varying loads (mowing, discing etc)if at all possible. After the 50 hours drain and refill it with your oil of choice, and a new filter,and a new hydraulic filter. I would also change out the antifreeze, and refill with a diesel rated coolant to prevent cavitation.

I like your idea of pumping oil into the sending unit and he will do that tomorrow.

I agree with MSM, I'm thinking that there is a small amount of light rust on the crank, so it should purge it's self clean, granted it will challenge the integrity of the original O/H a bit, bit it will still live a good life. After running it a while you will know if the water that you found was actually condensation. I have never heard or thought about 'pumping' oil in through an oil port, but it sounds like a good idea,,I'm thinking maybe loading a grease gun up with #30wt oil for the pump?? When water mixes with the oil it does make a "snotty"mess, while you have the oil pan off remove the valve cover too and using a "Suck Gun" (a blow gun that will suck up solvent and blow it out the end) blow down threw the push rod holes and flush off and out all that you can.
