  • Patent number: 4482166
    Abstract: A hitching guide including a guide block movable between a lowered hitching position and a raised hitched position. The guide block includes forwardly converging sides disposed to contact and laterally align the draft tongue in aligned relationship with a hitch pin. As the draft tongue moves to the hitching position, the forward end of the draft tongue contacts the converging sides and the aperture of the draft tongue is disposed immediately adjacent the hitch pin. As the hitch pin engages the aperture in the draft tongue and the draft tongue moves to the hitched position, the forward end of the draft tongue moves to a spaced relationship with respect to the converging sides. The forwardly converging sides are vertically spaced from the hitch pin such that the draft tongue is free to pivot laterally beyond the converging sides when the draft tongue is in the hitched position.
