If the problem is water contamination drain and flush as best you can. After thorough draining running 5 gallons of a "cheap" oil through the system as a secondary flush is not a bad idea if you can afford the luxury. Refill with a service oil that has some ability to resist water. That would be almost ANYTHING that is NOT a GL1 product. Modern gear and tractor transmission oils are formulated with the express purpose of protecting against that problem. Pure mineral oils lack that protection.
If your tractor is stored in an environment that lends itself to condensate formation you would be well advised to use an oil that is formulated to fight the problem as best it can. In the long run physical chemistry will prevail - all you can do is extend the drain and fill interval as best you can by using high performance lubricants.
