Abstract

See full text

An example snow blower machine includes a first stage snow mover and a second stage snow mover. Snow is received at an inlet opening of the first stage and expels snow to the discharge opening. In a second stage, an impeller chamber receives snow from the first stage. The impeller chamber extends from a snow receiving end proximate the discharge opening to a distal end rearward of the discharge opening. To receive expelled snow from the first stage and deliver the snow to a second discharge opening, an impeller rotatable around an impeller axis at a hub is disposed in the impeller chamber. The impeller may be rotated by an impeller motor having a motor body that is at least partially disposed within the hub.
