ABSTRACT:
An all-terrain vehicle includes a vehicle body with ground-engaging tracks and boom members pivotally mounted at each end of the vehicle which support generally cylindrical, cleated roller assemblies, the roller assemblies being characterized by having a plurality of fingers eccentrically mounted for extension and retraction with respect to the housing as the housing is rotated. Either roller assembly can be independently operated to perform digging and clearing operations as well as to permit lifting or lowering of the vehicle and at the same time cooperate in advancing the vehicle over uneven or hilly terrain.
