Abstract: A method for spreading a spraying liquid onto arable agricultural land by way of several switching elements arranged on an agricultural sprayer and controllable in an open-loop and/or closed-loop manner and in the manner of a pulse width modulation, where the spraying liquid is spread as required onto the arable agricultural land; where a first opening duration associated with a first switching element and at least one further opening duration associated with a further switching element is determined; where spreading the spraying liquid is influenced at least in part by way of the respective opening duration; where at least one upper and/or lower limit opening duration associated with the switching elements is used; and where the first and further determined opening duration is compared with the upper and/or lower limit opening duration.

Abstract: A control or regulating system for an agricultural working machine is provided, the system comprising a plurality of actuating elements that can be controlled individually or in groups, at least one control unit for receiving and/or sending switching commands to control the actuating elements, wherein the switching commands have at least one setting parameter setting and/or configuring the actuating elements, and at least one signal line to connect at least two actuating elements to the control unit for signal transmission. The switching commands are combined into at least one common group switching command that is transmitted via the at least one signal line, and the actuating elements are set and/or configured by the at least one group switching command. In turn, the efficiency and dependability of previous control or regulating systems is improved in a simple manner.

Abstract: A method for spreading a spraying liquid onto arable agricultural land by way of several spreading devices associated with a field sprayer; and arranged along a spraying boom, where the spraying liquid; is applied with a needs-based spreading quantity that is associated with the respective spreading devices where at least one first operating parameter associated with at least one first spreading device; and at least one second operating parameter associated with at least one second spreading device is determined, and where a difference between the operating parameters is ascertained and/or detected, and where the first and/or second operating parameter is adjusted if the difference is outside an acceptance range, where the difference is within the acceptance range after adjustment.

Abstract: Control and/or regulating system (200) for an agricultural working machine (100)—in particular, a distribution machine for spreading material over an agricultural area—comprising a plurality of actuating elements (103) that can be controlled individually and/or in groups, at least one control unit associated with the actuating elements (103), which control unit is designed to receive and/or send switching commands for the purpose of controlling the actuating elements (103), wherein the switching commands have at least one setting parameter (22, 23) suitable for setting and/or configuring the actuating elements (103), and at least one signal line, by way of which the at least two actuating elements (103) are connected to the control unit for the purpose of signal transmission.
