  • Patent number: 9920496
    Abstract: Piste grooming vehicle and clearing blade for a piste grooming vehicle. The piste grooming vehicle has a clearing blade arranged at the front and includes a middle part and two side parts swivellably movable relative to the middle part, a setting arrangement for adjusting the middle part and/or the side parts and at least one manually operable actuating element arranged inside a cab for operating the setting arrangement. An electronic control unit is connected between the actuating element and the setting arrangement and operates the setting arrangement with a timed sequence of control commands for achieving at least one control function for the side parts and/or the middle part from an initial position to an end position preset by the control function.
