Winter storage question
Earlier this year I bought a well-used Kubota U17 for maintenance and projects around my property. This is the pacific northwest, so some time in October it's going to start raining and not stop raining until June. I doubt I'll be able to do much work with the excavator when the ground is as wet as it's going to be, so it's going to sit for months.
What should I do to prepare for long periods of inactivity? For gasoline engines I'd drain the gas or at least put in a good stabilizer, but this is literally the only diesel engine I've ever owned and I don't know what you're supposed to do to keep it happy. It'll be under a lean-to, so no direct rain, but it will have to deal with ambient humidity. Should I just go out there and throttle it up for a while every week or something?
