| 20090051180 | SNOW REMOVAL TOOL - A manual snow removal tool used for the pushing and pulling of snow. The configuration of the tool allows the user to move snow by pushing the snow using a pushing blade or by pulling the snow using a pulling blade depending on the orientation of the snow removal tool. The snow removal tool may also incorporate fulcrum skids to allow the tool to remove snow more easily from rough surfaces. The fulcrum skids allow the user to raise and lower the scraping edge of the snow plow over the surface being scraped. The fulcrum skids move more easily across rough surfaces than the scraping edge of a regular plow or shovel. The snow removal tool may also have non-abrasive ends attached to the pushing and pulling blades so that it may be used on sensitive surfaces such as the painted finish on an automobile. | 02-26-2009 |
