ABSTRACT:
The invention comprises a snow removal accessory usable with a power-driven snow thrower and includes a circular convex disc which will slide freely over snow accumulation and mounting means on the disc which suspend the snow thrower device a predetermined distance below the level of the disc so as to control the depth of cut available to the snow-thrower device and prevent its sinking to an unworkable level in deep snow. The invention permits lightweight, low-volume snow-throwing devices to be used in deep snow by cutting successively deeper into the snow on successive cuts.
