Greetings, I'm dealing with a 1982 JD 570A grader, love the machine - however... Was spreading my 4th load of RAP as road base when suddenly the 'shift blade to left' stopped working. (T-handle) It stopped when I had the blade almost all the way to the right. It still shifts right, but I can't get it to back left to center position.
Hydraulics sound like it might be trying to move but not budging. I thoroughly cleared/cleaned slide channels from material that had packed in, and tried to bury toe and slightly roll forward while shifting left but no go?
Anyone seen this? I still need to confirm hydraulic fluid if full, but I did check it last week.
Any help would be appreciated if this might be semi common issue.
My old Gallon didn't have this feature so was never a issue.
