ABSTRACT:
A steering connection assembly that interconnects an implement train comprising first and second detachable implements towed by a draw bar of a tow vehicle is provided. The first implement is pivotally attached at the draw bar so as to rotate about a first vertical axis, and the second implement is pivotally attached to the first implement. The steering connection assembly includes a drive linkage pivotally connected at a draw bar so as to rotate about a second vertical axis. A steering linkage interconnects a rearward end of the drive linkage to a wheel assembly in support of the frame of the second towed implement. In response to a turn of the tow vehicle, a hitch coupling member generates a turn signal communicated via the drive linkage so as to cause the steering linkage to steer the wheel assembly of the second implement in a direction opposite a turn direction of the tow vehicle.
