If you switch to 12 volts and keep the 6 volt starter they really crank fasttttttt which can improve starting, although it can sometimes be a bit tougher on starter drives and gears.
On smaller tractors with good heavy batteries and 0 or 00 gauge cables and a well tuned good engine and the right oil, they can start okay at the stock 6 volts.

My 6 volt tractors started at 6 volts in cold temps and that was kind of neat....
The genny is fine if originality is an issue but an alternator is cheap and reliable and pumps more amps even at lowwwwwwwww RPM. I prefer the 3 wire GM 10SI family they are cheap and readily available.
If you swap polarity due to an alternator dont forget the ammeter leads and ignition coil leads need swapped.
