Abstract
A method for controlling a hydraulic top link of a three-point linkage on a piece of accessory equipment coupled to a tractor includes providing the top link coupled between a first location on the tractor and a second location on the accessory equipment. The method includes defining an extension position of the top link as a distance between the first location and the second location, where the extension position is adjustable within a predetermined adjustment range. The method further includes determining a force acting on the top link and adjusting the extension position of the top link by a control unit as a function of the force acting on the top link.
