Smooth – used for cleaning fresh fluffy snowdrifts of small height. Depending on the material of manufacture, work with wet snow is allowed.
Serrated – copes with snow of any structure. Serrated augers are capable of grinding even pieces of ice.
Structurally, there are three types of fencing systems:

Single-stage – the simplest design, it is one auger, which, rotating at high speed, simultaneously collects snow and feeds it into the chute. It is installed on non-self-propelled devices.
Two-stage. In addition to the auger, it is based on a rotating rotor (impeller) with 3-4 blades that crush the snow and feed it into the ejection system.
Three-stage – has the highest productivity and efficiency, as it is able to cope with large snowdrifts in a short period of time. Working mechanisms: central auger for crushing snow mass and feeding it into the discharge funnel, and two side augers for raking.
Material of the body and augers
The frame of snow blowers can be made of various metals, such as aluminum.

plastic, which significantly reduces the weight of the structure.

Instead of plastic, metal is germany mobile database used, but very rarely, since no load is applied to the body itself even during active operation.

When manufacturing the discharge chute, both sheet metal and plastic with sufficient strength characteristics are used.

The manufacturer selects the material depending on the expected load, that is, the speed of ejection and the volume of passing snow mass.

Plastic is cheaper, but when working in severe frost conditions it can simply crack and then break completely.

The auger is the most loaded part of the snow blower, it can be:

Plastic – has a smooth surface and can only work with fluffy snow.
Metal. For cleaning fresh and wet snow, rubber-clad versions are used.
The rubber one is made entirely of specialized rubber.
