The side sections (29,47) extend in the traction direction of the tool in the transport position and in the work position, they extend at right-angles to the traction direction. An inner side section frame (21) is fitted on each side of the frame (1). The inner side section is rotatable around an inner section rotary axis (10) extending at 45 deg. to the direction of traction of the tool in a horizontal plane in a position when the tool is connected to a towing vehicle. The inner section rotary axes (10) intersect each other at a point located along the tool centre line in the towing direction. |
