The snowmobile engine is very similar to the engine on a private motorboat. Heavier station wagons tend to use a four stroke engine, while lighter recreational vehicles use a two-stroke engine. The tracks of the snowmobile are made of lighter rubber, which can increase mobility and speed, while the tracks of the tank are made of rigid materials, because they must withstand impact and explosion when carrying heavy objects.

The body structure is simple, reliable and durable, all of which are caterpillar type. Most of them are rubber caterpillar reinforced with metal wire. The caterpillar is wide and the climbing slope is large, which is the basic feature of the existing snow truck.
