lights

Another question on my 57 620. Lights all of a sudden quit working. switch works as far as starting etc. and lights worked fine until they didn't. Any suggestions for trouble shooting. all wires seem to be hooked up etc.

You can check if you have power to them with a test light or multimeter if you do it may be a ground issue.
If no power to them trace wires back and see where you are losing power.

You might consider using a test light to ensure current from each ignition switch terminal to the head lights and tail light.

Take a look at the photo below of the terminals on the ignition switch.

Hope this helps.

If tractor is equipped with fenders then check fender to axle & light to fender ground connections
