ABSTRACT:
A convertible hitch for mobile equipment includes a first hitch plate attached to the mobile equipment and having a king pin protruding from a central portion thereof, and a second hitch plate with a central aperture mounted on a wheel and axle assembly which includes a tow bar member. A ball joint is provided between the second hitch plate and the wheel and axle assembly to provide for relative movement therebetween. The king pin protruding from the first hitch plate includes a circumferential groove which is engageable with a securing mechanism of a releasable fifth wheel, so that the mobile equipment can be transported on the highway by a conventional highway vehicle, such as a semitrailer truck. The king pin of the first hitch plate is also receivable in the central aperture of the second hitch plate, so that the first and second hitch plates can be removably fastened to one another to in turn attach the wheel and axle assembly to the mobile equipment. When the first and second hitch plates are fastened to one another, the tow bar of the wheel and axle assembly may be connected to the tow bar coupling of a conventional field vehicle for towing of the mobile equipment in the field.
