NAA hydraulic problem

[jbeeje]

I hadn't used my 3 pt hitch since last fall, and the lever was in the fully raised position. I had used the tractor a couple of times on a pto elevator, but hadn't used the 3 pt. I was going to use the 3 pt rear blade yesterday, but the 3 pt seems to be stuck in the raised position. Could a valve be stuck, or what could be the problem here?

Yes the control valve could be sticking or if the arm have been in the up position for a long time they may have rusted that way and may take something heavy to get them to go down. Easy way is to pull the inspection plate off and work the control by hand
