Hello from a happy gray market tractor owner, I have a sd2643 it's the same as a ford 1900-1910. The set of switches on the rh side on mine are not wired to anything except the large knob op front it's for the 3pt. Lift. The large handle by your right leg would operate the 3pt lift if the electric switch was not on it.the valve that moves the lift is moved by two elect. Moters that the joy stick switch works. You can post questions on the ford new holland forum and buy parts manuals for.
