Although Washington never really sees the cold that many see, I found it pretty effective to use battery maintainers in both tractors and dump truck. You have to spin them fast to get the heat in the cylinders. I have drop cords off the barn ceiling where they park that attach easily. I also pull the fuel stop manually and crank it for about 5 seconds then release the lever to allow fuel to the cylinders while cranking.
