Abstract

An arrangement for mechanical measurement and for regulation of a pulling force of a tractor, has a bending-elastic element whose bending is sensed by a sensing device which acts on a lifting device for a three-point linkage of the tractor, wherein the bending-elastic element is formed as a pin which is hollow and supports one link of the linkage between two housing-fixed bearing points, and the sensing device has a gauge stick which extends inside the pin substantially between both housing-fixed bearing points.
