The mouldboard (1) is suitable for attachment to a grading apparatus for operations such as unsealed road maintenance. The mouldboard (1) comprises a body with separated first and second opposing edges (6a, 6b), a leading face and a rearward face. The opposing edges (6a, 6b) each comprise a grading edge or provision for the attachment of one or more grading edge components (3, 4) to adapt the opposing edges for a grading operation. The body further comprises mouldboard attachment means (2). The attachment means (2) include a pivotable connection portion (5) substantially equidistant from the opposing edges (6a, 6b) which allows connection of the mouldboard (1) to the grading apparatus. The pivotable connection portion (5) allows pivoting of the mouldboard (1) about an edge conversion axis substantially parallel to the opposing edges (6a, 6b) or a line bisecting the opposing edges (6a, 6b).
