  • Publication number: 20040040184
    Abstract: The present invention is a lightweight, one-person-operating plow designed to remove new-fallen or otherwise soft snow or slush. It is inexpensive to manufacture, ship, market, and purchase. Its two units can be assembled and connected to any kind of vehicle in less than one minute. Disconnection and disassembly can be effected in like time. It can remove virtually all of the snow from the path being cleared very quickly; for example, a 100-foot driveway can be cleared in about fifteen seconds, and a 50-foot driveway in half that time. Very little physical effort by the user is required, and no damage is caused to the surface being plowed.
