  • Snow-removal device
    Patent number: 6003916
    Abstract: A snow-removal, such as a snow shovel, snow plow and the like, includes a heated blade. The snow-removal device might also provide a selection of temperature settings for the heated blade. The snow-removal device at least fluidizes the snow when the blade slices into it, whereby the fluidized snow lubricates the interface region between the blade and the snow, diminishing the physical effort required.
