The Air Jet Shovel includes skids to glide over grooves in sidewalks, driveways and decks. Over time through use the skids will automatically wear down to the optimum height for the leaf blower that you are using. When the skids are at their optimum height the shovel blade edge will be in contact with a surface when the user is holding the leaf blower at a normal height. When approaching a groove in a surface, the user may lower the leaf blower which in turn raises the shovel blade edge above the surface so that shovel glides over the groove while supported by the skids. This prevents the shovel blade edge from catching on the groove. Watch the You Tube video “Customize AJS Skids for Gliding Over Grooves in Sidewalks and Driveways” at
