Bruce, don't think that I am doubting you because I am not. I just read on one of these forums a few days ago how much easier a tractor would start using bigger cables and that put me to wondering why.

Big cables are for 6 volt system where the amp draw is twice as high as 12 volts. I use the auto type battery cables on my tractor that have been switch to 12 volts and never had any problems

think of you trying to put out a fire, you got a garden hose and you are doing a fair job, then someone gives you a hose that is a little bit larger, like a 1" hose, (old one was standard 1/2")the amount of water is far greater, more flow. The pressure could have changed too.
In electricity, water flow is kinda like amperes, and water pressure is like voltage.
the two combined make the big picture. In electricity this term is Watts ( total power)
If your starter on your tractor needs, 100 watts of power to do its job (number made up) - the old 6 volts X 16+ amps would be the amount of total power, but if you changed to 12 volts, the amp load would have gone down to 8 or so. The larger cable you are thinking about are needed due to the larger amp flow ( think water flow) for the 6 volt. New cars have the same ol batteries but the starters are probally easier to turn over the engines might be easier to turn over so the amps could be less. the ol adage "bigger is better is true in elecrical terms......HTH
