Abstract
A mine clearing rake comprising a rake assembly with alternately disposed large and small teeth which are arranged to form a broad 'V' and are rigidly supported laterally by horizontally disposed bars and rods to provide a maximum proportion of open space rearwardly and are supported rearwardly by a rigid reinforcing frame assembly which is attached to the bottom edge of the moldboard of a propelling vehicle, such as a tank, and have four additional points of support and/or attachment to the moldboard. An extension grid assembly is also mounted above the rake assembly to prevent unearthed mines from rolling over the mine clearing rake. A skid shoe assembly is attached to the reinforcing frame assembly and protrudes through the rake assembly so that the skid shoe rests upon the surface of the minefield during operation of the mine clearing rake.
