The frame of a seed drill can be connected to a tractor by means of two linkages extending in a V-shaped manner relative to one another in the working position. The ends of the linkages (12) located at the rear in the direction of travel are connected to vertically movable frame carriers connected to one another in an articulated manner. To prevent the linkages from rotating about their longitudinal mid-axis, they are equipped with ball joints (37) allowing all-round movement and received in a carrier part (34) which can be connected to a tractor by means of a coupling bolt (13) via a fork-shaped horizontally pivotable joint part. <IMAGE> |
