" I put my meter on it, it indicates 6.55 volts,"
A volt meter will tell you if you have a bad battery, but as you just discovered, it will not tell you if you have a good battery.
You can string a few flashlight batteries together & get 6.5 volts, but that won't start your tractor.
It's the current (amps) that count.
Normally, a fully charged battery will show 6.35 volts after the surface charge wears off (about 24 hours).
See tip # 50 for the best way to test a battery.
