Wondering this myself, since I just took receipt of my B7800, 402 FEL, 60" MMM, 60" Front Blade and a Woods BH 70X. All this is in my garage and my car now sits in the cold. (Added a Modine Hot Dawg heater 75k BTUs to the garage to keep the orange from turning Blue).
Outside 5 car garage is to full of other things to get any vehicles/tractor in. Started -7F other day block-heater NOT plugged in. Beside if problems or some reason need to shut down away from house want to know it will start by self if cold soaked.
