Point 4: Protruding parts
Headlight and chute adjustment handle protrude beyond the width of the auger housing, so that every time you clear snow e.g. along a wall you have to take care of these parts. If you are lucky the wall is build from loose snow and the headlight is scratching decorative pattern into it. If the wall is massive, the headlight gets broken and the handle becomes bent. This could be easily changed in the factory by moving these parts more to the inner side.
