We are all free to do what we want but we are also free to give advice. One moderate sized 12 volt will crank it just fine unless you use it in real cold weather. Up until a few years ago I ran two bangers year round, mainly a 630 but also a 51 A. They had two 6's years ago and started very well, but I was always messing with corroded cables. After I switched to one 12 in both tractors the cable corrosion trouble was reduced by 75 percent. There is something about that cross cable between the two batteries that spells trouble. When the 630 was the loader tractor it would start dependably at -20 with one 800 amp battery. I have had lower amp batteries, like 650 amps in the 630 and it would sometimes start at -20 but if there was a hickup I would be out of luck. But that's at -20 for Pete's sake. The 51 A doesn't start quite as well as the 630, maybe because of the 12V coil. I would expect a hot mag to start it better than the distributor but I have no evidence to prove it. Both tractors are fair weather tractors now so I don't have to worry about using a big battery anymore.

He was the one with the threshing machine, a JI Case on steel wheels, and he pulled it to our farm with a JI Case standard tractor also on steel. In those days, steel wheeled implements were common. The roads were general gravel, so the lugs cutting into them wasn't a problem. George would set up the thresher, s
