windy ridge · May 18, 2020

changed hydraulic fluid in a g450 yesterday.today I noticed hyd fluid dripping from the cotter pins sticking through the bottom of the tractor near the rear drain plug.wasnt leaking there before.what are these?any ideas why it would leak there?thanks

not familiar with that model but I would think it a drain for when the seal or seals leak. the cotter pin prevents plugging. the oil can run out. some times they are used in vent plugs also.

Maybe it got a piece of dirt in it.

I filled it to the top line of the dip stick.If it was overfilled is there a possibility it would run out of those holes?
