Implement with drive motor and rotary blade, especially grass mower

摘要

The rotary blade is connected to and disconnected from the drive motor by a coupling. A safety bracket (8) and pivoting adjusting lever (16) are for opening the coupling. A locking element (23) operated by the safety bracket mechanically engages with the adjusting lever by a catch, and is in the form of a longitudinally adjustable pawl. One end (23<1>) of the locking element has an opening into which fits a pin (22) fixed to the safety bracket preferably with no play. The locking element is slide-mounted in a guide element (27).
