A while back my friend Bob M and I discussed this very issue. My thought was when using 12 volts on a 6 volt starter (since it spins so fast and engages harder anyway) to lessen such a hard shock on the starter drive (which can be a bit tough on them) you dont really want such a high CCA battery, say use a 500 versus a big heavy honkin 1000 like you would on a 12 volt system and a 12 volt starter. He thought use a big battery but maybe use slightly smaller gauge battery cables when applying 12 volts on a 6 votl starter to reduce some of the higher kick in torque which can be tough on drives.
THIS IS STRICTLY A GUESS AND A SOMEWHAT EDUCATED OPINION but on a Super C with a 6 volt starter Id say a 500 to maybe 650 CCA 12 volt battery will spin her as fast and long as you should ever need and in my opinion a big heavy honkin 1000 CCA is nottttttttttttt needed and could be real tough on a starter drive (Heck even a 500 CCA will cause her to enage fast n harder then normal and still spin real fast)

The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
