Convertible horse wagon

A four-wheeled horse wagon which is readily adaptable into a two-wheeled towing trailer comprising:

• main frame means for supporting a wagon load having two coaxially aligned wheel means operably mounted at a mid portion of the main frame for rollingly supporting said main frame;
• goose neck means operably mounted on a forward portion of said main frame means for providing clearance between said forward portion of said main frame means and a front end assembly means;
• front end assembly means for attachment to said goose neck means for steerably rollingly supporting the front end of said main frame means having a transversely extending front axle means for supporting wheels and having front wheels journaled at either end thereof in coaxial alignment with the central longitudinal axis of said front axle means, the front end assembly means being substantially as wide as said main frame means;
• draw bar means operably attached to said front end assembly means for attaching at least one horse to the horse wagon;
• ball hitch means, comprising a ball means and a socket means for mating, selectively disengagable attachment one with another, for providing limited universal pivotal attachment between said goose neck means and said front end assembly means to allow free pivotal movement of said front axle means about a tiltable generally vertical steering axis, said steering axis being defined by a line substantially perpendicular to said central longitudinal axis of said front axle means and substantially coincident with a center point of said ball means, for steering the horse wagon and to provide limited swiveling movement between said ball means and said socket means to prevent excessive loading on said draw bar in uneven terrain or surfaces of changing grade.
