| 主权项 | 1. An aerating device for a ground, the device comprising: a frame; moving means arranged on the frame for the purpose of moving the aerating device in a direction of movement over a ground surface for working; a drive; and a rotor shaft provided with a plurality of knives, wherein the rotor shaft is arranged bearing-mounted between the frame and the drive, wherein the rotor shaft is operatively coupled to the drive for the purpose of rotating the rotor shaft, wherein the knives are inserted successively into the ground surface, wherein, during uncoupling of the rotor shaft from the drive, the rotor shaft with the knives is movable with respect to the frame in an axial direction of the rotor shaft away from the drive such that the rotor shaft lies clear at a distance from the drive. | ||
