Arrangement of a mowing head, an output shaft for receiving a mowing head and a fastening device for fixing the mowing head on the output shaft, and work apparatus with such an arrangement

An assembly, comprising:

• a mowing head (3),
• an output shaft (8) for receiving the mowing head (3), and
• a fastening device (10) for fixing the mowing head (3) on the output shaft (8),
• wherein the output shaft (8) can be driven to rotate about an axis of rotation (9),
• wherein the assembly (2) has an anti-rotation lock (11) and an axial lock (16),
• wherein the mowing head (3) is held corotatingly on the output shaft (8) by the anti-rotation lock (11),
• wherein the axial lock (16), in a blocking position (30), positively secures the mowing head (3) on the output shaft (8) against relative movement along the axis of rotation (9) of the output shaft (8) and, in an inoperative position (31), releases the mowing head (3) for detachment from the output shaft (8), and
• wherein the fastening device (10) comprises an actuating element (24) accessible to an operator, the axial lock (16) being switchable into the blocking position (30) and into the inoperative position (31) by means of the actuating element (24).
