The cultivator has cutting tools attached to one end of a support arm whose other end is swivelably mounted on a frame (6). frame is associated with a vertically acting drive rod (8) and a double-armed adjustment lever (12) which swivels about the attachment axis (10) of the tool holder (4). The downwardly projecting arm of the lever has a stop (18) aligned with an area of tool holder under the link axis (10). The upwardly projecting arm (16) is associated with an adjustment device (20) for determining the angular position of the l relative to the support arm and thus through the stop, the insert angle of the tool relative to the ground. The tool holder is biased by a spring unit against the stop and exits when plunging in the ground through the resistance which occurs against the travel direction against spring force.
