I have a 1957 TO35, it came from the factory with a 12 volt system,
If you tractor has been changed from 6 volt to 12 volt,
you might want to check the serial number, it might not be a 1959 model?
I buy the battery with the largest cca that will fit in the battery box, normally I buy from autozone, have had good luck with their batteries,
US made batteries,
I also changed the battery cables to size 1 cables, the larger the cable the more power/current to start the tractor on a cold morning,
