For the hafts (11a, 14) of the loosening bodies (15, 16) of so-called subsoilers, guards are provided on the tools against damage caused by stones or such like obstacles located in the soil. In these guards, the respective lower haft part (11a) is connected bendably counter to the direction of travel (F) via a bolt (6) and shearing pin (7) to an upper, that is to say frame-side haft part (30), the latter being designed as a torsion-resistant closed box section (32, 33, 34). <IMAGE>
