  • the Nachhoffmschar 3 is the same length as the ploughshare 1 is formed, arranged parallel to this and is laterally the same extent as the ploughshare 1 before. If the snow plow is tilted, for example, as in FIG. 13b shown, pivoted to the left, the Nachhoffmschar 3 is laterally to the left by the dimension a less far ahead than the ploughshare 1. On the opposite side, however, is the Nachhoffmschar 3 by the dimension a further laterally to the right before the ploughshare 1. This has the disadvantage that the detected by the Nachhoffmschar 3 snow residues are not laterally promoted far enough outward to prevent over driving through the wheels 4 of the vehicle. On the opposite side, where the Nachhoffmschar 3 further protrudes laterally outward, however, it comes to high loads on the end of the Nachhoffmschar 3 due to snow masses that have not been detected by the leading ploughshare 1.
  • the invention has for its object to provide a snow plow of the type mentioned, with which the Räumense improved and excessive loads in the end portions of the Nachhoffmschar can be avoided. This object is achieved by a snow plow with the features of claim 1. Advantageous embodiments of the invention are described in the further claims.
  • the Nach Hurmschar is guided laterally displaceable on the ploughshare holding device. Furthermore, a displacement drive is provided with which the lateral position of the Nachhoffmschar is variable relative to the ploughshare.
