Abstract available in
FIG. 1 is a perspective view of a snowmobile tract showing my new design, it being understood that the tread pattern is repeated uniformly throughout the length of the track as shown schematically by solid lines; and,
FIG. 2 is an enlarged top plan view of the tread pattern thereof.
The track has been broken away in FIG. 1 to indicate indeterminate length.
