The arrangement has a retaining groove arranged in a shovel carrier. Longitudinally extending projections are arranged at side walls of the groove for forming undercuts. Each of shovels is pressed against the projections by a plate-shaped element (46) that is arranged between a shovel base lower side and a groove ground of the groove. The element includes seams (86) arranged below the blade for pressing the shovel in the groove. The element is fully covered in a longitudinal direction of the groove and partially covers a shovel base (50).
