Abstract: The invention relates to a method for smoothing or leveling a ground surface, wherein a smoothing or leveling material is laid on a ground surface in that a box-like device filled with material is moved forwards, the material being allowed to exit a plate-adjustable rear opening in the box-like device and to come to lie in a strip, and a blade mounted on the box-like device after the opening spreads the material on the ground surface, the blade being capable of being raised and lowered together with the plate, the blade is raised and lowered with an adjustable reduction ratio relative to the plate, by means of a lever/parallelogram arrangement which connects the blade and the plate.
