<p>The implement has a vibration generator with a vibrating piston (42) which is mounted in linearly displaceable manner in a casing so as to be spaced from a working unit (5). The piston is driven in oscillating manner for generating vibrations. The vibrations can be transmitted to the working unit through the casing. The vibrating piston has two piston surfaces, where one surface is subject to an alternating pressure. An independent claim is also included for a method for introducing a working unit into the ground.</p> |
