The present invention is directed to levelling apparatus, typically as used on tractors, excavators and skid-steer vehicles, and references the levelling assembly and mounting options including directly to the existing blade of vehicles as well as other mounting arrangements. Preferred embodiments of a levelling apparatus include a blade body portion and body mounting portion connected by an arrangement of fixed and adjustable linkages, preferably hydraulic, to allow movement of the blade body portion (relative to the body mounting portion) in substantially an up and down direction, as well as rotational movement about an axis perpendicular to the general plane of an attached blade. |
