CA 2561754
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.
