Hey Fellas, Whats the third aux hydro line that i see on some machines used for?
Sometimes high flow auxiliary, sometimes a low pressure return to tank, like for a hammer.
could also be for motor case drain Mark
most likely a case drain, but specifically what make and model of machine are you looking at? :drinkup
I dont have a specific model in mind. Seen them on bobcat s300s. Gehls ect. The line seems to always be smaller than the other 2 though
on a bobcat it's a case drain line that goes direct to tank. on later bobcats with the coupler block, it serves more as a pressure release "vent" for the spring loaded couplers. :drinkup
