Swivel hitch adaptable for use with either a tractor drawbar or two-point hitch

摘要

The forward end of a draft tongue of a towed, power take-off driven implement carries a transmission including an upper right-angle gear box rigidly fixed to the tongue and a lower right-angle gear box swivelly mounted to the tongue for rotation about a vertical yaw axis. A swivel hitch includes a frame secured to the lower right-angle gear box and to an upright extending pivot member forming part of the swivel mounting of the lower right-angle gear box. A longitudinal pivot member is swivelly mounted to the hitch frame along a roll axis. In one embodiment, a vertical clevis is fixed to a forward end of the longitudinal pivot member and is pivotally connected to a drawbar adaptor for relative rotation about a horizontal transverse pitch axis, the latter being located close to the rear end of a drawbar received in a receptacle defined by the adaptor. In a second embodiment, a transverse arm is fixed to the forward end of the longitudinal pivot member and carries forwardly extending vertical clevises respectively at its opposite ends, the pair of clevises being adapted for connection to a pair of tractor draft links with the connection pins effecting the connection being located along a pitch axis.
