In contour farming operations, it is important that the path of an implement
precisely follows the path of the tractor that pulls it. An alternative
implement positioning method is proposed that avoids the use of steered
coulters or wheels: unequal drag forces from differential dig depths of the
implement's wings linearly slews the rig, changing its path. The
experimental rig, an AFM-880 cultivator, has a span of 10m and a
drawbar length of 5m. It was found that position could be arbitrarilly set
versus the nominal center by as much as 48 cm if the wing heights were
caused to differ by 30 cm. The calibrated simulation of the uncontrolled,
natural path of a trailed rig on a sinusoidal path was compared with the
path generated when the rig was actively steered differentially, showing a
significant reduction in path undercut, a prerequisite to garnering the full
benefits of controlled traffi
