The grading vehicle has a grading blade which is guided displaceably on the frame of the vehicle transverse to the longitudinal direction of the vehicle. In order to obtain automatic readjustment of the guidance of the blade upon the occurrence of wear and play in the guidance, the blade is displaceable, by means of two guide ledges which extend horizontally on the blade and are spaced vertically from each other, between upper and lower slide pieces, the lower slide pieces being movable vertically and being pushed by spring force against the lower guide ledge of the blade.
