Abstract

An open-loop or closed-loop control system for an agricultural utility vehicle includes a distributor linkage for dispensing fertilizer, plant protection agent, or seed, and has a center part and two lateral extension arms connected by joints to the center part with a plurality of linkage sections (4) which can be folded relative to one another in a transport position and folded out relative to each other in a working position. The control system also has at least one sensor and a data processing unit configured such that signals of the sensor are processed so as to generate a control signal for the hydraulic device, and the hydraulic device can be controlled in order to set damping of vibrations occurring on the distributor linkage in a direction of travel.
