Abstract (en)
[origin: EP1477633A2] A drilling tool (11) e.g. drilling screw or worm is fitted to a drilling rod (10) that is rotated about a rotation axis by a rotary drive (20). A feed drive (30) lowers the drilling rod into a soil area (1) as the drilling rod rotates. A control device (40) reduces the feed rate of the feed drive when a decrease in the speed of the drilling rod is determined. An independent claim is also included for a soil working device.
