There is also at least one side blade element which abuts the central blade element end to end. Additionally, other side blade elements may be releasably fixed outwardly from the side blade adjacent to the central blade. Preferably, the blade elements also have upwardly extending flanges adjacent to their lateral edges so that they may be fixed to adjoining blade elements by releasable connecting members such as lock pins. Preferably, the blade elements are also concave in shape as viewed from their upper surface and terminate at their lower ends in an angled cutting edge.
