Abstract: A mobile soil aerating device including a machine frame, a drive, at least one penetration tool hingedly coupled with the machine frame, said penetration tool being adapted to be driven into the soil and to be pulled out again, said penetration tool being pivotable with respect to the machine frame during a penetration phase in which the penetration tool, prior to penetration, being in an initial position at a predetermined penetration angle, and wherein, at least after having pulled the penetration tool from the ground, at least one element engaging the penetration tool and coupled to the machine frame exerts a restoring moment on the penetration tool in order to pivot the penetration tool back to the initial position.

Abstract: A mobile soil aeration device including a machine frame, a drive, at least one guide arm that can be moved up and down by the drive and that is pivotably arranged on the machine frame, at least one articulated piercing tool that is coupled to the guide arm, said piercing tool can be lowered into the soil and withdrawn therefrom, a tool holder for the piercing tool, that is mounted about a first pivotable axis in the guide arm that can be displaced up and down by the drive in order to allow the piercing tool to pivot in relation to the guide arm when engaging with the soil.

Abstract: The invention relates to a movable soil aeration device (1) comprising a machine frame (2), a main input shaft (12) for connection to a drive, an output shaft (14), preferably a crankshaft, coupled to the main input shaft (12) via a reduction gearing (3), which output shaft is adapted to move at least one piercing tool (4) up and down. Said piercing tool (4) is adapted to be pushed into the soil (44) and to be pulled therefrom. The invention is characterized in that different transmission ratios can be set at the reduction gearing (3).

Abstract: A mobile soil working device, comprising a machine frame, a drive for at least one piercing tool, a guiding element, moveably guided on the machine frame, for at least one piercing tool, a tool holder for the piercing tool, which holder is mounted around a first pivot axis in the guiding element is provided. It is provided that the overall center of gravity of the tool holder and the at least one piercing tool is arranged in relation to the first pivot axis in such a way that the moment of inertia of the tool holder and the piercing tool that counteracts the restoring moment is at least partially reduced or compensated or overcompensated in such a way that the moment of inertia acting around the first pivot axis forms at least part of the restoring moment.
