Claim 11:
12. A method for controlling an agricultural utility vehicle comprising:
applying material, by a distributor linkage, the distributor linkage extending transversely to a direction of travel, and comprising a center part and two lateral extension arms which are connected to the center part by joints and having a plurality of linkage sections connected by additional joints which are configured to be folded in relative to one another in a transport position and folded out in a working position,
wherein the center part is arranged movably along a vertical axis for height adjustability of the distributor linkage,
wherein at least one hydraulic device is assigned to each of the extension arms, whereby a respective one of the extension arms is configured to be pivoted about a horizontal axis, wherein at least three sensors are assigned to the distributor linkage,
wherein a first sensor is configured to determine a first distance, the first distance being between the center part and the ground;
wherein a second sensor is configured to determine a second distance, the second distance being between a first lateral extension arm and the ground;
wherein a third sensor is configured to determine a third distance, the third distance being between a second lateral extension arm and the ground;
wherein the control system comprises a processor which is configured such that measurement signals of the sensors are processed as actual values so as to generate an actuating signal for the hydraulic device for adaptation to a target distance, and
wherein pivoting of the extension arms is based on the target distance which is formed by the current actual value of the center part, and
wherein the processor is configured to:
calculate a mean value from the actual values representative of the second distance and the third distance; and
compare the mean value with the current actual value of the center part.
