The original subject was "David Brown 990a Hydraulic bypass valve issues please help".
our 990 3point arms wont lower. WE have the control valve out and cleaning it up. Numbers 16 in the diagram in the thread above wont come out. The book we have
calls this part the lowering valve or plunger. We've sprayed knocker loose, gripped it with vise grips.. even heated it. Are we out of luck if this plunger
does not move.
