Abstract
An ice scruffing device for scruffing a covering of ice on a ground surface to improve the ability of the ice to retain de-icing chemicals on its surface. Paddles are mounted radially about a drum that is mounted substantially parallel to the ground surface and transverse to the direction of travel of a prime mover of the ice scruffing device. Each paddle bears a plurality of impactors. The impactors are made of flexible wire cable, with a strike element arranged at the end of the cable. As the drum rotates, the strike elements strike the ice on the ground surface at high velocity, thereby creating random, discrete indentations, cracks, pit-marks in the surface.
