In a self-propelled soil aeration device comprising a machine frame (18), a plurality of upwardly and downwardly movable piercing tools (2) which are arranged next to each other transversely to the direction of travel and which define the width of a working path on the soil (2), at least two rear wheels (6) which run laterally alongside the working path, and at least one front wheel (5) which is arranged in front of the piercing tools (2) as seen in the direction of travel, it is provided that a supporting device extending transversely to the direction of travel is arranged in front of the piercing tools (2), as seen in the direction of travel, and is vertically adjustable with respect to the soil (3) such that in a working position, the rear wheels (6) are raised and the machine frame (18) is supported on the supporting device and the at least one front wheel (5) so that neither the front or rear wheels (6), nor the supporting device travel over the soil (3) already worked by the piercing tools (2), and that in a transport position, the supporting device is raised and the machine frame (18) is supported by the rear wheels (6) and the at least one front wheel (5).

L'invention concerne un aérateur de sol automoteur comprenant un bâti de machine (18), plusieurs outils de piquage (2) qui peuvent monter et descendre, lesquels sont disposés transversalement par rapport au sens de déplacement et déterminent la largeur d'une bande de traitement sur le sol (3), au moins deux roues arrière (6) qui tournent latéralement à côté de la bande de traitement et au moins une roue avant (5) qui est disposée dans le sens du déplacement devant les outils de piquage (2). Selon l'invention, un dispositif support qui s'étend transversalement par rapport au sens du déplacement est disposé devant les outils de piquage (2) dans le sens du déplacement et il est réglable en hauteur par rapport au sol (3) de telle sorte que dans une position de travail, les roues arrière (6) sont soulevées et le bâti de la machine (18) s'appuie sur le dispositif support et sur ladite roue avant (5) de sorte que ni les roues avant ou arrière (6), ni le dispositif support ne passent sur le sol (3) déjà traité par les outils de piquage (2), et que dans une position de transport, le dispositif support est soulevé et le bâti de la machine (18) est porté par les roues arrière (6) et ladite roue avant (5).
