ABSTRACT:
A clearing blade, as an attachment for a garden tractor or the like, is constructed as a double-walled construction thereby forming a box-like spreading funnel (5) between the wall members so that simultaneously with or after clearing snow, salt or other granular material may be spread by the same implement used for the clearing. Due to the rigid box-structure of the blade a sufficient strength is obtained even by materials of lesser strength than expensive, fracture resistant steels. Hence, such materials of lesser strength, e.g., synthetic materials, may be used for manufacturing the present blade by an injection molding or die-casting method.
