I'm the proud new owner of a 2016 2025r with only 29 hours that was in a garage since new (tractor is like new). Question, where should the oil level be on the sight glass for the transmission? When the machine is off (and cold), the whole sight glass is covered with oil. When it's running, the level drops down to almost the bottom. The book says when it's cold, the oil level should be at the 3/4 mark. Anyone have experience with this?
