The present invention relates to a rear finisher for smoothing an outer surface, which is attached in the forward direction behind a device for outdoor preparation and particularly for snow piste preparation. In order to allow a uniform appearance of the piste surface, the rear finisher has a guide device, which is applied so that the material to be prepared is guided in front of the bottom of the rear finisher and subsequently smoothed thereby. Furthermore, the present invention relates to a method for smoothing an outdoor surface, in which the outer surface to be smoothed is smoothed by two different oscillating means guided one after another on the outdoor surface.

A device for generating a circular oscillation or a directional oscillation is provided. The device provides a circular oscillation, or, if two parallel main shafts rotating synchronously in opposite directions are coupled, a directional oscillation, each main shaft having unbalance weights and a coupling between the unbalance weights and the oscillation amplitude of the exciter force per main shaft being continuously adjustable between a minimum value and a maximum value using an adjustment unit via the relative rotation of the unbalance weights toward or away from one another. The device includes unbalance weights that are mounted on the main shaft so they are rotatable thereon, and the coupling comprises a transmission medium connected rotationally fixed to the main shaft, which is composed so that it acts as a driver on the unbalance weights and also causes a pivoting of the unbalance weights in opposite directions upon the adjustment of the oscillation amplitude of the exciter force.

The invention relates to an apparatus for snow surface preparation for attachment to a tractor, comprising a vibration plate and a hydraulically driven exciter device for driving the vibration plate, with the exciter device being connectable to a working hydraulic system of the tractor and being driven by the same in such a way that a closed hydraulic circulation is produced between exciter device and working hydraulic system. In order to reduce the risk of overload of the exciter device, a control device is provided which monitors at least one operating parameter of the hydraulic circulation and functionally disconnects the exciter device from the working hydraulic system depending on a predetermined limit value for the at least one operating parameter. The invention further relates to a method for controlling a hydraulic circulation between a working hydraulic system of a tractor and a hydraulically driven exciter device for a vibration plate of an apparatus for preparing the snow surface which can be attached to the tractor.
