Abstract
A soil working method and device, in which a drilling rod, to which is fitted at least one drilling tool, is rotated about a rotation axis with a speed using a rotary drive. The drilling rod is simultaneously lowered into a soil area in the direction of the rotation axis using a feed drive and with a feed rate. The drilling rod speed is determined and a control device decreases the feed rate when the drilling rod speed is reduced.
