Abstract:
An ice scarifying tool replaces the grass cutting blade of a conventional rotary-type power lawn mower, so that, as the mower is operated over icy surface and the tool rotates in a plane substantially parallel to an icy ground surface, depending fingers chip and scarify the surface to provide improved traction thereon. The tool comprises a support plate which may be in the shape of a substantially rectangular elongate bar, a disc or a cruciform. Coiled ice scarifying fingers are attached to the plate. An ice scarifying tip at the distal end of each finger extends groundward from the support plate. A bag attachment or auxiliary blower may be provided for removal of the chipped ice, or it may be removed by power sweeper or plow.
