Abstract (en)
[origin: EP2106679A1] The self-propelled soil aeration machine, to insert and withdraw a probe (4) into the soil (8), has a return unit (30) for the probe holder (6) to bring it back to the start position. It lies parallel to and at a gap from the plane through a swing axis (14) and the probe holder and probe. The return force is offset at the probe holder so that the lever moving around the swing axis is increased to the maximum probe holder deflection in relation to the start position. The return unit is a spring, integrated into a guide arm linked to the machine frame (2) and the probe holder.
