The invention relates to a smoothing and balancing device (10) for ground surfaces, comprising a screed (11) having an essentially flat base area (12), a shaft extractor (20) attached to the screed (11), by means of which the smoothing and balancing device (10) can be pulled in the pulling direction (ZR) across the ground surface, and a drive motor (31) having a vibration device (32) that can be driven by this drive motor (30), wherein a control unit (50) is provided in pulling direction (ZR) behind the screed (11), which comprises a base plate (54) attached to the screed (11), as well as means for the height and/or incline measurement (52, 53). The base plate (54) particularly can be attached to the screed (11) by means of a loose bearing (55). Means for an acoustic and/or optical warning signal may also be provided such that the warning signal is activated if a predetermined height and/or incline threshold value has been exceeded. |
