Image Number 5 for United States Patent #8136269.
A bottom of a snowplow defines a front, plowing surface and an inverted shelf disposed directly behind the plowing surface, and the shelf defines a first side abutting against a rear of the plowing surface and a second side of the shelf extending away from the rear of the plowing surface. A backblade-and-snowplow system comprises a bent, rigid blade defining a top and back and at least one hole in the top of the blade corresponding to a hole defined in the second side of the shelf. At least one fastening mechanism is passed through the corresponding hole defined in the second side of the shelf and the hole defined in the top of the blade to secure the blade to the shelf. At least one L-shaped bracket defines a top edge secured along the top and back of the blade and a first side of the bracket positioned flush with the first side of the shelf. The first side of the bracket further defines at least one hole suitable for receipt of a corresponding fastening device that passes through the first side of the shelf and the hole of the first side of the bracket to secure the blade to the shelf such that a substantial entirety of the blade is disposed directly behind the plowing surface of the snowplow.
