Snowcat

A snowcat is an enclosed-cab, truck-sized, fully tracked vehicle designed to move on snow.

Snowcats used for snow grooming are also called 'piste machines', 'trail groomers' (in North American English) or 'piste bashers' (in British English) because of their use in preparing ski trails ("pistes") or snowmobile trails. Most snowcats, such as the ones produced by Bombardier or Aktiv in the past, have two sets of tracks, fitted with a Christie suspension or a Vickers suspension. Others, like the Tucker Sno-Cat and Hägglunds Bandvagn 206 vehicles, have a complex arrangement of four or more tracks.
