MOST of our snowfalls are pretty light, and the smaller snow throwers / snow blowers with rubber paddles actually work better at cleaning down to the pavement. Occasionally there is a deep snow, or it gets packed hard by the plows, where a 2 stage machine with metal impellers is better. Like chainsaws, one could justify having a few different types for different conditions.I would think you would want a two stage snowblower with caterpillar tracks judging from your location.
EGO has a whole line of battery powered Outdoor Power (you know what). They have been around for several years with Li-Ion products. Cold weather performance is an interesting issue for battery powered stuff. With my chainsaws I quickly learned that there was nothing to warm the bar oil!It does not in those pictures say if it uses lithium ion batteries. We have discussed prior the differing low temperature limits published for batteries Husqvarna vs Oregon.

Starting to see 120V stuff. Not sure if it is 'better' or just 'different'. Battery weight is always an issue with hand held equipment - less of an issue with wheeled equipment, like lawnmowers, snow throwers, tillers, etc.If they come out with a larger chainsaw that I can plug both my batteries into chances are I would get one.
