The problem with not changing the oil in a tractor that's only run 25 hours a year, is that the oil is contaminated by water from condensation inside the engine block--assuming the tractor isn't kept in heated, humidity controlled storage anyway. That water gets mixed into the oil upon start-up and gets pumped around the engine, which probably then gets shutoff before the oil gets hot enough to "burn off" the water in the oil as vapor. You can figure out what happens when you mix water, time, and internal engine components.
