<p>The agricultural roller is drawn by a tractor and comprises at least two side sections fitted on a frame provided with wheels and pivotable between a transport position and a working position. In the latter position, the roller axis extends at right-angles to the direction of traction. The roller side sections are fitted on an outrigger which (at one end) is pivotable around an axis extending in the roller traction direction, and which fits on the frame. The side sections rest on the frame in the transport position and are brought to the outrigger by a rotary joint.</p> |
