If you do the conversion , do not get the coil that does not need the ballast resister(3 ohm coil). Get the 1.3 ohm 12volt coil and the proper ballast resister with it. Use the existing (or install) starting bypass wire so that you will get full voltage to the coil when starting.
The 3 ohm coils have a high resistance wire in it to increase the resistance to 3 ohms. The winding ratio is unchanged from the 1.3 ohm coil. As this coil has no way to bypass this additional resistance when starting , when cold the tractor will be much harder to start.
Also the heat generated by the ballast resister will now be generated inside the coil increasing resistance and shorting the life of the coil.
