Abstract

See full text

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