ABSTRACT:
A hitch and drawbar assembly (10) arranged so that bolts (38) securing the hitch (17) to the drawbar (18) have substantially only tension forces applied thereto in transmitting a pulling force from the vehicle (11) to the hitch. The drawbar of the assembly is pivotally mounted to the frame (12) of the vehicle by suitable pins (15,16) and a support (21) is provided for retaining the drawbar in a desired, generally horizontal, slightly downwardly rearwardly inclined disposition. The support is arranged to permit slight movement of the drawbar longitudinally while maintaining the drawbar against pivotal movement so as to assure the transmission of pulling forces from the vehicle frame to the drawbar substantially solely through the pins. The drawbar may be thusly supported to a casing portion (20) of the vehicle as such mounting assures the prevention of transmission of pulling forces on the casing portion.
