The first snow with enough ground accumulation for the snow blower to work is probably the best time to fire up the device and make sure everything is working. Even if the blower may be over kill and not the most efficient way of clearing the snow. Better find out the blower needs a new cog or widget when it’s only 1 inch of accumulation than when it’s 6 inches.
It’s the fake psychic prediction methodology.
A shotgun approach.
