The invention relates to an aerator device. One end of the blade shaft of said device bears a v-belt pulley that projects above the chassis. In order to operate, the v-belt pulley that drives the blade shaft is supported on the chassis by means of an end shield and is provided with a coupling part, which interacts with a counter-coupling of the blade shaft. The coupling is configured as a spur-gear coupling and can be tightened by a threaded bolt that is guided through a central bore of the shaft section, the latter bearing the power-take off v-belt pulley and the coupling gear. The other end of the blade shaft is mounted into an end shield, which is detachably fixed by screws to the chassis.
