without knowing more, I will give the following:
If it has three cells (three caps on the cell coverings that either pry or screw off, it is a six volt. If it has two big square covers, covering 3 openings each it is a 12 volt.
The reality is that it came from the factory as a 6 volt if it is a gas tractor, and 12 volt if diesel. Both of these were positive ground systems (not the same as modern cars)
If you know the difference between an alternator, and a generator by looking at it, you can be assured it will have 12v negative ground (99% chance)if it is an alternator.
If it has a genreator, it will have an external device attached near it, or in the wiring to it for control (either a cutout relay, or a voltage regulator) We can help dramatically if we know what you have with certainty. Google images of Delco farmall Generators. The fifth image I found was typical. Then look at delco SI 10 alternator images. they do not look the same. Give us a photo, or tell us what you have. Putting the wrong battery in it the wrong way always lets the smoke out of the parts. JimN

Today's Featured Article - Converting from 6 Volt to 12 Volt - by Chris Pratt. It's a common problem for old machines especially when the weather starts to dip below 40 and the tractor isn't fired up as often. You are probably used to the 12 volt Diehard, charged with 200 amp alternator of your 3/4 ton that always is ready and always starts. It's this type of experience that brings about the many queries we get for 12-volt conversion kits. Since only a few kits are available (we sell kits for the ... [Read Article]
