Abstract
A method of controlling the combination of a tractor and an attached implement includes the calibration of a tractor/implement combination to allow for variations in prevailing slip-pull data at progressively increasing implement draft levels. The recorded data is then interpolated at a reference slip value and compared with a series of reference slip-pull curves. The slip-pull curve approximately most closely to the recorded pull value at the reference slip value is then selected for subsequent use in a control algorithm.
