ABSTRACT:
A laterally yieldable or "bendable" hitch pole is provided for the steering mechanism of a trailing vehicle to minimize or prevent breakage of the hitch pole during sharp turns negotiated by the draft vehicle, especially during backing of the trailer. The invention is especially applicable to trailers having steering mechanisms of the Ackerman type. The hitch pole is typically swingable between right and left stops and breakage or other damage occurs when the pole encounters one or the other of the stops and turning forces are still applied. The invention provides a two-piece hitch pole having its end-to-end parts connected in such manner as to enable "bending" of the hitch pole in those situations with subsequent recovery of the pole to its normal attitude.
