If the battery is dead, there will be no power to excite the alternator, so it cannot create electricity.
True that the gassers can be push/pull started with the rear-pump transmissions, but you do need electricity to make it happen. with the diesels, you just need the shutoff lever up. With the diesel also however, you need electricity to excite the alternator so that it will charge, so a little battery power will be necessary.

Even if the battery was dead, roll starting it would turn the alternator fast enough to generate enough electric to make a spark. It would take a lot more generated electric to heat the GP in a diesel with a dead battery.
