Though certainly not Original, it is normal. Changing to 12v (especially with an alternator) is desirable in that it makes jumping it simple. It also makes jumping polarity - to - and + to + obvious.
A cub will start using 4 flashlight batteries (just kidding) so conversion to make it start better is nonsense. If it is charging leave it alone and enjoy, they are great tractors.

its been changed, several reasons for doing that first a 6v system cranks more slowly than a 12v, if your not old enough to be used to the sound you will think there is a problem, and if all the connections are not clean, brite and tight with 0 or 1 ga cable on the battery, there will be a problem especially in cold weather, as mentioned with a cub in proper tune, it takes very little effort to start it but another advantage of 12 v systems is being able to use modern lites and other electrical stuff on the tractor, some put electronic ignitions on them if its a distributor style ignition, but i feel most of those are done by people who dont realize how simple points are to work with, us older people grew up with point systems and there just not a big deal, but you do have to get them installed right, or you'll have a no start problem
