All 6V and 12V John Deere's of the two Cylinder variety had positive ground
set ups.

Was looking at some old tractor stuff online and was reminded of something I
have know for years but have never, at least in my failing memory, seen a
plausible explanation as to why most 6 volt tractors have positive grounds
whereas 12 volt tractors have negative ground.  At first I thought it could
be because 6 volts had generators, however, our first 12 volt tractors had
generators and later models had alternators so that doesn't seem to be the
reason. Any and all answers would be great.
