In order to pivot the entire scoop laterally, a further piston and cylinder unit is integrally provided for lateral pivoting of the entire scoop about a central pivot axis in the attachment head, the further piston and cylinder unit is connected at one end with a pivot point, preferably one of the pivot axes of one of the scoop sections, and at the other end with a lever. The lever is connected at one end with a pivot point, preferably the other respective one of the pivot axes on the other respective scoop section and the other end of the lever is connected via a link with a projection on the attachment head.
