Furthermore, a wider corridor of forces can be set because the actuator can be adjusted more finely using the deflector.
  • the deflector can be, for example, a cross member or the like, which has a first deflection point that is attached to the milling box. Furthermore, the diverter can have a second deflection point, which is fixed on the adjustment unit. In addition, the deflector can have a third locking point at which the actuator is fixed.

  • An advantage of this embodiment can be that the driving dynamics of a snow groomer to which the rear cutter is attached can be improved by means of the mutually independent side finisher units, since the individual adjustability of the position of the side finisher units can prevent the snow groomer from tilting if the surface is uneven.
  • the adjustment unit can be arranged on one side of the milling box and a second adjustment unit can be arranged on the milling box opposite the first adjustment unit.

  • the connecting elements that attach the holding plate to the milling box can reduce the load and wear of each connecting element by doubling them.
  • the predetermined track and the second predetermined track can be arranged, positioned and/or provided parallel, concentric and/or symmetrical to one another.
  • rotation or displacement of the holding plate to the milling box can be improved, since the second predetermined path blocks a degree of freedom in the displacement and thus the holding plate can only move along one direction of displacement to the milling box.
