Compensating spring Compensating spring for the connection of the 3-point triangle structure to the frame, for the absorption of substantial undulations in the ground surface. 4. Counter-blade In order to prevent any blade failure at the point of attachment associated with repeated bending, the entire DBS range is equipped with counter-blades. 5. Flexible teeth Spring steel flexible teeth for the effective scarification of grassland. 6. Scrapers Scrapers arranged perpendicularly to the ground, in order to prevent any destruction of grass by the repetitive hopping associated with topsoiling. 7.
