Abstract
A method for determining a physical parameter of an adjustable upper link of a three-point hitch during a working operation thereof includes providing a lower link of the three-point hitch and an implement attachable to the upper and lower links of the three-point hitch. The method includes generating calibration data prior to the working operation of the three-point hitch, where the calibration data defines a relationship of a length of the upper link to an upper link angle defined between the upper link and a reference line. Moreover, the calibration data is used to determine a physical parameter of the adjustable upper link during the working operation.
