Another option for cold starting assistance is to go to a auto performance supplier like "Jegs.com" These guys who drag race like to keep the oil hot between pass's. You can purchase a heating pad type of thing that will attach to the oil pan and warm the oil. They are available in different wattage and can be removed easily before you go out on the track. No reason it would not work on a tractor to pre warm the oil for about a hour or so before start up.
