My blade control is getting a little loose and was wondering if anyone has tackled this repair. It seems there is a lever between the handle and the actual valve , I wonder if this is the problem. I believe the same control is on other dozers like the 39EX-22 and up to the 65.
Trying to help a fellow farmer with a D61PX has same issue, a lot of free play in valve control. Were you able to fix it up? I have looked at the parts diagram but don't have a feel for how the control mechanism runs the valves.
