Abstract: A snow grooming devise is provided with a carrier frame consisting of at least one transverse supporting member and two longitudinal supporting members so that it is adapted to be attached to a vehicle with the aid of a coupling means. A vertically adjustable snow propeller and a smoothing board are mounted on the carrier frame. The carrier frame is mounted on said coupling means such that it is adapted to be pivoted about an essentially horizontal longitudinal axis and an essentially horizontal transverse axis. The snow propeller is dragged by the front ends of the longitudinal supporting members and is pivotably mounted thereon and the transverse supporting member is associated with the coupling means so as to support the carrier frame.
