4. The working device according to claim 2 , wherein the arm is arranged on the first part and the locking opening is arranged on the second part.

5. The working device according to claim 1 , wherein the first part is supported by a spring loading the first part in the direction of an open position of the at least one lid.

6. The working device according to claim 1 , wherein the at least one propelling drive is switched off when the at least one lid is not completely closed.

7. The working device according to claim 6 , further comprising a drive device for at least one tool of the working device, wherein the drive device is switched off when the at least one lid is not completely closed.

8. The working device according to claim 1 , further comprising a drive device for at least one tool of the working device, wherein the drive device is switched off when the at least one lid is not completely closed.

9. The working device according to claim 1 , wherein the second part comprises at least one locking contour that, in the closed position of the at least one lid, locks on the housing and secures the at least one lid in the closed position.

10. The working device according to claim 1 , further comprising a sensor configured to detect at least one pivot position of the first part.

11. The working device according to claim 1 , wherein the pivot bearing comprises at least one receptacle arranged on the housing and comprising a circumference with an opening, wherein the bearing section is supported in the at least one receptacle and the bearing section is inserted into the receptacle through the opening.

12. The working device according to claim 11 , wherein the opening is arranged on a side of the at least one receptacle that is facing away from the second part of the at least one lid.

13. The working device according to claim 12 , further comprising a stop switch embodied as an actuating button arranged on the housing and at least partially covering the opening, wherein the actuating button is configured to be operated by an operator, wherein the at least one propelling drive and/or a drive device for at least one tool of the working device is switched off when the actuating button is pushed by the operator.

14. The working device according to claim 1 , wherein on the first part a stop is formed that is interacting with the housing and defines a completely open position of the at least one lid.

15. The working device according to claim 1 , wherein the at least one lid performs a travel stroke from a completely closed position into a completely open position across a pivot angle of approximately 70° to approximately 110°.

16. A self-propelled working device comprising:

at least one propelling drive;

a housing;

a pivot bearing arranged on the housing and comprising a pivot axis;

at least one operating element arranged on the housing;

at least one lid pivotably supported on the housing, wherein the at least one lid comprises a bearing section arranged in the pivot bearing so that the at least one lid is pivotable about the pivot axis;

wherein the at least one lid comprises a closed position and covers in the closed position the at least one operating element, wherein the at least one operating element is accessible in an open position of the at least one lid;

wherein the at least one lid comprises a first part and a second part connected to the first part, wherein the second part is connected to the first part by at least one detachable connection;

wherein, when pivoting the at least one lid from the closed position into the open position, the first part and the second part pivot together about the pivot axis of the pivot bearing;

wherein the second part of the at least one lid covers the at least one operating element;

wherein, when a constructively predetermined pulling force is applied to the second part, the at least one detachable connection separates and the second part detaches from the first part;

wherein the constructively predetermined pulling force at which the second part detaches from the first part is smaller than the weight force of the working device so that the working device cannot be lifted by gripping and lifting the second part of the at least one lid.

17. A self-propelled working device comprising:

at least one propelling drive;

a housing;

a pivot bearing arranged on the housing and comprising a pivot axis;

at least one operating element arranged on the housing;

at least one lid pivotably supported on the housing, wherein the at least one lid comprises a bearing section arranged in the pivot bearing so that the at least one lid is pivotable about the pivot axis;

wherein the at least one lid comprises a closed position and covers in the closed position the at least one operating element;

wherein the at least one lid comprises a first part and a second part connected to the first part, wherein the second part is connected to the first part by at least one detachable connection;
