I was going to go the 8 volts route on an SC and DC CASE. After research on YT and a local tractor salvage parts store owner who had several people there who had been there for years, said no on the 8 volt system. Too many changes to be made with little improvement. Said one needs amps, not volts. These Guys talked from experience. Yes, it is hard to find a good 6 volt battery. I converted both tractors to 1/0 cables. From battery to starter button, and button to starter. Also put in cut -out switches, so there is no drain, as these antiques tend to set a lot. That way they are OFF! Also when displayed at county fair, they are off. Some kids gets on there and pulls the ignition switch ondead battery! I was having starting problems for a long time with both tractors. Replaced coils, wires,plugs, rotors, distributor capswent through it all. Then had starters checked and rebuilt if needed. Then had carbs cleaned and rebuilt. Not much change in starting! Actually worse on one of them. The problem was the starter buttons! These are momentary switches. Replaced them, now both start good. I tore those old switched apart. Simple spring loaded contacts inside. Burnt! That was the problem in the first place. Keep fresh fuel in them. Add a quart of that super fuel they use in small engines, 4 cycle,also add fuel stabilizer( StarTron) , and keep trickle chargers on the 6 volts. Not sure if the super fuel helps, but actually I had best luck on 6 volt batteries from local farm supply store and also from a Wal mart battery. Hope this sheds new light and good luck. By the way, should one still use lead additive in these old tractors? Its hard to find. Maybe if one was farming with them, maybe not just for show and parade.

Today's Featured Article - What Oil Should I Use? - by Francis Robinson. I keep seein this question pop up over and over again in discussion groups all over the web. As with many things there are often several right answers and a few wrong ones. Some purist I'm sure will disagree to no end with what I will tell you but most of us out here in the real world don't really care do we ? Some of them only bring their noses down out of the air long enough to look down them anyway. If you are like me you are only doing this old tractor stuff because you enjoy it. You
