- working machines are used to treat and/or process agricultural land. Such working machines can be carried and/or pulled by a tractor or be self-propelled. Such working machines include, for example, distribution machines that are used to spread solid, in particular granular, and/or liquid material. This includes, inter alia, sowing and/or fertilizer machines for depositing seeds and/or fertilizer or field sprayers for applying sprays, such as weed control agents, plant protection agents and/or fertilizers. In addition to spreading machines, such agricultural working machines also include soil cultivation machines and/or plant treatment devices, in particular cultivators.

- This results in a particularly high throughput of switching commands through the at least one signal line if settings and/or parameters of individual control elements have to be adapted to the needs of the usable area and/or the environmental conditions, in particular to the driving speed of the work machine.
- a dynamic adjustment of the application quantity of spraying agent by means of a field sprayer for example when driving in or out of and/or during cornering, is problematic here.

- the duty cycle of the control element 103 with the identifier X36 is adjusted to 50% and the duty cycle of the control element 103 with the identifier X41 is adjusted to 100%.
- the control element 103 with the identifier X36 thus has a lower output quantity of the material, in particular spray agent, than the control element 103 with the identifier X41.
- the respective duty cycle of the actuating elements 103 with the identifiers X37 to X40 is adapted to an intermediate value interpolated by the open-loop and/or closed-loop control system 200, in particular by the computer unit and/or control unit. If, as shown in this exemplary embodiment, the starting value 22a, in particular the first duty cycle, is smaller than the end value 22b, in particular the second duty cycle, the intermediate values are assigned to the actuating elements 103 with an identifier lying between the first and second identifier 21a, 21b X1 - X44 are assigned in the ascending order of the identifiers X1 - X44, with the intermediate values being in ascending order.
- the fourth group switching command 20 includes a second setting parameter 23 with a start value 22a and end value 22b, in particular a pulse frequency of 40 Hz.
- the fourth group switching command 20 also includes a first identifier 21a with X15 and a second identifier 21b with X20.
- the respective pulse frequencies 12 of the actuating elements 103 with the identifiers X15 to X20 are adjusted to 40 Hz, in particular set and/or parameterized.
- the frequency of the opening and closing operations of the actuating elements 103 actuated here is therefore increased compared to the other actuating elements 103 .
- the adjusted settings and/or parameters of a respective control element 103 are maintained until they are adjusted again by a subsequent group switching command 20.
- FIG. 7 shows an exemplary flow chart of a method for operating an agricultural working machine 100 according to the invention with a control and/or regulation system 200.
