If your tractor is in good shape, tuned well, with good (and HEAVY) cables, good connections, and has a good starter and generator, a 6-volt battery will start it. If your tractor has been "tinkered with" by adding high compression pistons and an overbore kit, 6 volts may not do it satisfactorily. I have a Farmall H with a 6-volt system. I have no intention of changing it. I have a Farmall M and a Super M that have been "improved" to the point that a 6-volt battery (even with the good cables, new starter, etc.) will NOT turn either over easily when it's really cold, or when trying to re-start a hot engine. About 15 years ago, we put 8-volt batteries in both the M and SM. They spin over easier, the lights are brighter, and I've had NO problems with either of them due to this change. The generators have charged the 8 volt batteries just fine with NO changes to the regulators. The rpms simply had to be a little higher for charging to begin. The front bearing in the M generator only lasted 54 years, and went out recently. I'm in the process of converting it to 12 volts rather than rebuilding the generator. I'll keep it, in case anyone wants to put it back someday. In short, it's your decision. I wouldn't depend on changing batteries to cure other problems, but if other parts are in good shape and it won't spin the way you want it to, 8 volts will help.

Bad Vibes - by Curtis Von Fange. One of the strangest ways to communicate with our tractor is to ask it how it feels. "Ask it how it feels," you say? Yup, ask it how it feels. Now, as with the other articles in this series one has to be able to hear what 'ole blue' is trying to say in response. The nice thing about our old iron friends is that they are usually quite consistent in their response, rather unlike some people I know who might change what they say due to the weather or other mitigating circumstances. But since t
