they are called groomers. and their intention is to level the surface of the snow and to aerate it to become more moisture induced. With more moisture within the snow, the snow will then create more of a hard pack base on it.
those groomers seem like big heavy machines, but truthfully they exert such little pressure onto the snow due to their big tracks that sometimes they are rendered unable at times.
