Abstract (en)
[origin: WO03025289A1] The invention relates to a ground surface cutting device comprising: a cutting motor (2) for rotationally driving a cutting tool (4); an advancing device (6) for displacing the cutting tool (4) with an advancing speed relative to the ground surface, and; a rotational speed measuring device for measuring an actual value for the rotational speed of the cutting tool (4) or of the cutting motor (2). The actual value is evaluated by a control device and is compared with a predetermined set value. The control device controls the advancing device (6) and changes the advancing speed based on a variation of the actual value from the set value.
