Tractor Hitch

I have a 1953 Farmall Super C tri-cycle tractor with the Fast Hitch option. A somewhat rare option for that year. My grandpa gave me the tractor after he died, and I am trying to restore it. The generator is in bad condition, along with the old wiring. The tractor hasnt moved under its own power in about two years. The tractor has no lights (a idiot tried to restore it years ago, but did a $hitty job, making it worse off than before) and none of the gauges work. We put a switch instead of a key on it, and it has a new 6 volt coil. (thats how we got it moving two yeasr ago, but now it wont start no more) I figure a 12 volt system will make it easier to work on, but take away from its show look. (I dont plan on restoring it that much anyway, I dont have much money) It needs rebuilt, new gauges, new wiring, new genrator/alternator, and a new hydrulic pump.
What is your opinion on whether I should convert it? Dont say to scrap it because it was my grandpas before it was mine and he gone
