the invention relates to a zinkenstriegel - eindringtiefenmessvorrichtung 2.a continuous measurement of the depth of penetration of the striegelzinken and automatic regulation of the penetration depth in different soil conditions to enablehas the zinkenstriegel - eindringtiefenmessvorrichtung 2 a carrier 12.the carrier 12 is mounted to a traverse reference striegelzinken 13 and a abstandsmessvorrichtung 14 adjacent to the reference striegelzinken 13 to measure the distance to the surface of ainvestigating soil 10, and a sensor 16 for measuring the deflection of the reference striegelzinkens 13 is provided.so that the distance of the deflection and the depth of penetration of the reference striegelzinkens 13 in the processed soil 10 is identifiable.
