My 4701 lives here where it can be even colder than yours. I use mine all year, in the winter mainly for snow removal and hauling firewood. Will yours be used in winter or stored?
I would check the antifreeze, first. If the tractor won't be used, I would opt to remove the battery and store it indoors. Check tire pressure if tractor will be used...cold air will condense air in tires and they will read lower than you might want. If stored for the winter, I doubt that would matter.
