Anyone know where the breather for the hydraulics is on a DB 880 selectomatic? I had a post about water in the hydraulic fluid and was told to change the fluid and the rest of te water would propably evaporate out the breather. But I can't find one on my tractor. Also I my temp gauge doen't work. I want to replace it, but I am not sure if a standard gauge will stand up to the weather, or do I have to find a gauge specifically for tractors.
