12.8 would be considered 'fully charge' at room temperature( 70*F).
When you say 'over charging' what does the ammeter register ?

For a 12V 40 Amp alternator I'd say it's spot on. Anything less than 12.5V or more than 15V would be an issue. Why do you think it's overcharging?
My mistake. That was suppose to be 15.8v. There is no amp meter12.8 would be considered 'fully charge' at room temperature( 70*F).

The only thing controlling the voltage is the regulator. Being a 40 year old tractor did you buy new or used parts?I have replaced the alternator, New regulator,
If you can, check the voltage output at the alternator not the battery. Check the voltage at idle and full RPM's. Voltage should be similar or just slightly higher if the regulator is good.
Side note (you probably already know) - operating while overcharging will kill your new battery in short order.
