Abstract

A method is provided for controlling the operation of an attachment that is coupled to a tractor via a top link and two bottom links of a powerlift. The method includes selecting a point of action from at least one of a pull point as a geometric intersection of imaginary extensions of both bottom links and a pole point as a geometric intersection of imaginary extensions of the top link and a bottom link. The method also includes determining a position of the selected point of action, and signaling the determined position of the point of action by a display unit or adjusting the determined position depending on a comparison with a setpoint setting.
