MF135 Lift arm stay up all the time.

james allen The tractor ended up with water in the hyd/trans. Changed oil 4 times. Now arms will not go down. Has a whining sound. Like it is stuck in constant pump? Any suggestions, James
C Willoughby You may have to split the tractor and check the pump. We had this happen before also withthe water. It actually froze the valve open causing it to be in lift mode continuously. If this is the problem, you should be able to free the valve and make sure it works smoothly. If there is corrosion on it, you may have to replace it.
james allen Thank you. You have to split the tractor to remove the pump? Looks like it may come out with out splitting?
