(under the class definition) Apparatus in which a mounting mechanism is provided for connecting an earth working element to, and ahead of, a self-propelled vehicle.
(1) Note. Basic subject matter for this subclass, and those indented hereunder, is the mounting means (e.g., a frame and adjusting linkage) intermediate a tool and a vehicle. The tool, the vehicle, or a control system for the adjusting linkage may be claimed as well, but this is not necessary for classification herein.
(2) Note. The earth working element is in front of the vehicle in its direction of travel when the element is in use. Included in this subclass, and those indented hereunder, are patents disclosing a tool attached to the rear of a vehicle, but wherein the vehicle moves in its normally reverse direction when using the tool.
(3) Note. A significant portion of the earth working element must be located ahead of a transverse line corresponding to the axis of the front wheels, or forward track idlers, of the vehicle. However, a tool comprising a transversely elongated blade, such as a bulldozer, may be angled (i.e., pivoted within a horizontal plane about a generally vertical axis) so that a portion of the blade is to the rear of said transverse line and outside the perimeter of the vehicle.
