ABSTRACT:
A steering connection assembly is provided that interconnects a towed implement with a tow vehicle. The steering connection assembly includes a tongue member having a forward end pivotally connected at the tow vehicle so as to rotate about a first vertical axis, and a rearward end fixed relative to the frame of the agricultural implement. A drive linkage has a forward end pivotally connected at the tow vehicle so as to rotate about a second vertical axis. A steering linkage interconnects the rearward end of the drive linkage to a series of caster wheel assemblies in support of the frame of the implement. In response to a turn of the tow vehicle, the drive linkage communicates a turn signal via rotation about the second vertical axis so as to cause the steering linkage to steer the caster wheel assembly in the turn direction of the tow vehicle.
