The SnoCobra ski system essentially converts your ATV or side-by-side into a snowmobile, allowing you to use your machine in the winter on snowmobile trails if allowed by the state. Using an ATV or side-by-side on snowmobile trails without skis and rear tracks is prohibited in most states because wheels can gouge and rut trails, which makes the SnoCobra ski system a great option.

Trail use and snowmobile definitions vary by state. Check with your local, regional and state organizations to verify that SnoCobra skis with rear tracks installed on your machine meet the
definition of a snowmobile. Your local ATV, off-road and snowmobile clubs are also great resources to find trail maps and areas open for use.

Every Season Products promotes safe and lawful operation of machines for the enjoyment of all outdoor enthusiasts. Never ride on posted land without permission and always use care and consideration of the environment.

The table below clarifies the definition of a snowmobile by state. Check with your state for trail fees or licensing before riding in your area.
