Too look at it one way.. voltage is pressure, and current is flow. An 8 volt battery if charged correctly, will have 33.3% more pressure than a 6 volt battery. And would pull 33.3 % more current assuming your cables are still 6 volt (2/0) cables. SO... by simply making a small adjustment to the voltage regulator, you can.... spin the engine over faster.. meaning that it will develop more compression on a cold crank.. and, it will have enough voltage to have a hotter spark. SO... the engine should... start quicker, with less cranking time. IF your six volt tractor is perfectly tuned and in perfect condition, you will probably see no difference. If your six volt tractor has been down the field many times, you probably will see a difference, mainly on starting times.
Problems with this. most folks replace bad battery cables with small 12 volt cables that only have to carry smaller cranking currents. But with a six volt starter, you must have the very large cables still in place, even with a 12 volt system.
second, they dont adjust the voltage reg up to correctly address the 8 volt battery(9.46 volts), so your not really gaining anything as the battery is under charged, and could actually be worse in this undercharged condition than a six volt that is charged correctly(7.1 volts).

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
