I have two 35's each with its own set of hyd problems. one the hyd drifts down immediately after depressing the clutch the other the lift arms will not go down.
yesterday while walking past the lift arm problem tractor I decided to press down on the lift arms. the arms went down (had to push hard) but I could hear "gurgling" inside the tractor. the engine had not been running. is there a clue there as to the problem ?
