ABSTRACT:
An ice and snow clearing device includes a brush, a heating element, a scraper and means for electrically powering the heating element. The sweeping member brushes snow or ice from the surface that is to be cleared. The scraper is connected to the rear of the brush to remove snow or ice remaining in the path of the brush. The heating element softens snow or ice remaining on the surface after operation of the brush to facilitate removal by the scraper.
