[AT] JD 620 / charging six-volt batteries

[Gunnells, Bradley R]

Someone correct me if I'm wrong. But if you plan to use the 6v better tender you will need to put it on only 1 battery and disconnect the short cable that ties them together in series. If it's cold and snowing, connecting and disconnecting battery cables might not be the most enjoyable task. I'd opt for leaving everything together and just swapping he 12v unit between tractors.
