Abstract
A snow tiller for ski slopes having rotating cutter bars with outstanding teeth. The cutter bar is installed beneath a cover which directs the snow rearwardly to a snow smoothing comb. The cover is adjustable in geometry to provide either greater or less angle of entry of the snow beneath the snow comb, and the change of angle is coordinated with changes in depth of snow cutting by the cutter bar teeth.
