Abstract
In the realm of snow grooming devices for ski hills, a unique snow tiller is disclosed. The snow tiller is pulled by a tracked vehicle and has a snow chamber which can be varied in size and dimension. The tiller is also equipped with a cutting drum which works the snow for a longer period of time when the snow chamber is enlarged. By varying the angle of the trailing bar mounted on a flexible membrane, which forms the outer bounds of the snow chamber, more or less snow is retained in the chamber depending upon snow conditions.
