A regulating and/or control system for an agricultural machine includes a distributor linkage for spreading material, such as fertilizer, plant protection products, or seeds, the distributor linkage being pivotable about at least one axis of rotation extending in the direction of travel, with at least one first sensor device for determining the inclination of the distributor linkage; and a data processing device for processing the sensor signals. The system further includes at least one second sensor device for determining the centrifugal force FF and/or the centrifugal acceleration aF acting upon the first sensor device when the machine is turning corners, where the data processing device is configured such that an inclination measurement error of the first sensor device can be corrected based on the sensor signals of the second sensor device.
