Oh, by the way, when you change your hydraulic filter you can plug this vent hose temporarily and it will make changing the filter a little less messy. Instead of a gush of fluid coming out the fluid flow out of the reservoir (tank) will just be a trickle because there is no air coming in to displace the fluid. This gives you time to change the filter. And if you forget to unplug the air vent and you cycle the hydraulic cylinders, as in raising and lowering your Front End Loader, it will blow the dipstick out into a graceful arc in the air and land it several feet from the tractor in the dirt. Don't ask me how I know that.
