ABSTRACT:
The mowing implement of a mowing apparatus, rotating about a vertical axis, is driven over a transmission comprising a freewheel mechanism and driving pins. A drive shaft is connected with the freewheel mechanism so that there cannot be any mutual rotation therebetween. In a basic orientation parallel to the axis of rotation of the mowing implement, these driving pins produce a driving connection between the freewheel mechanism and the mowing implement for driving the latter. In the event of a stoppage of the drive shaft, the driving pins, together with the freewheel mechanism, carry out a lifting motion, which interrupts the driving connection between the mowing implement and the freewheel mechanism. During their lifting motion, the driving pins activate a braking device in the region of the interior of the transmission housing above the freewheel mechanism. This braking device rapidly brings the mowing implement, which continues to run, to a stop.
