Like others said there are some advantages and disadvantages too. Many like the new 6V Optima battery in a 6V system too though many dealers won't stock them they can order them in. One disadvantage putting 12V on a old 6V starter that isn't converted with proper coils and armature for 12V is it the old 6V may then spin too fast and the starter drive won't work right as it should and if starter is worn out yes you finish it off into just junk. If you want more reliability and easier to find parts or to be able to boost it and a working machine a modern internal regulated 12V neg. ground alternator, 12V converted starter are the way to go. You'll have to put a 12V ignition coil on it too and reverse connections on coil and amp meter if going to negative ground and it was originally positive ground. You can probably price conversion kits on this site and other tractor supply places and then compare with what you can get done with local electric shop too. Like Gerald said connections and cables may be your only problem or just a better battery and a starter overhaul. Don't use the wimpy automotive supply cables on a tractor. Go with some HD cables or get some custom made locally at truck or battery shop or can even use HD welding cable with solder on or crimp on ends of copper and brass not those wanna be bolt on repair ends.
