Sometimes I have to leave a snowblower outside at a site long enough for it to get cold. I have electric start on it. I also have a Duralast jump starter 900. Can I rig that to operate the electric start motor on the blower?

The snowblower starter is probably 120V a/c
You would need an ac/dc booster pack with an Invertor built in

Get your self a little two stroke generator and leave it in the truck.
