摘要：

The device can be raised from ground contact by the tractor hydraulic system. The frame carries a large number of narrow soil working implements e.g. harrows etc. which can be arranged in working or transport positions so that the device is narrower in its transport status than in its operative status. It has the component parts mounted onto the system by means of guide devices which allow the component arms to be pivoted relative to the main frame. Three guides lie behind one another in the transport status and extend lateral to the direction of travel of the device.
