Yes.

Take a look at the [b:654c4848f0]John Deere Model "H" Diagrams[/b:654c4848f0] below.

Nice diagram, pretty much universal for any tractor from that era with a magneto ignition system. So the "switch" on the starter would be mechanically activated from the operator's platform. Why is wire 7A shown as being a dotted line in the diagram I wonder?

I believe it's just the 6 volt systems that are positive ground. Just about every 6 volt system I have seen is positive ground. The only exception I know of is my Ferguson TO 20. I'm sure there are a few others. SAE standards since about 1957 required negative ground. I don't know if they included 6 volt systems in that requirement.
