DRAW BAR SWIVEL HITCH |
摘要 |
A pull-type implement has operating components that are driven by a mechanic al drive line on the tongue of the implement. An upper gear box is fixed to the front end of the tongue and a lower gear box swivels relative to the upper gear box about an upright axis passing through the two gear boxes. A hitch that establishes a draft connection between the tongue a nd the draw bar of a towing tractor has a fore-and-aft receiver that extends beneath the lower ge ar box and has a lower pivotal connection with the tongue at that location. A mast fixed to and projecting upwardly from the receiver has an upper pivotal connection with the tongue at a location above the upper gear box. The receiver has a forwardly facing socket that loosely receives the draw ba r to permit the draw bar to swing up and down to a limited extent about a transverse axis and rotate side-to-side to a limited extent about a fore-and-aft axis when the draw bar is retained within the socket by a locking pin. One embodiment isolates both gear boxes from all draft loads, while a second , pull-through embodiment places a limited amount of draft loading on the lower gear bo x.
