ABSTRACT:
An implement includes a clevis assembly connected to the forward end of the implement hitch for limited fore-and-aft movement to permit holes in the clevis and of a tractor drawbar to become aligned for receiving a hitch pin, a latch then being operable to prevent further fore-and-aft movement of the clevis. First and second parallel legs of the clevis are provided with holes in which are received first and second bushing portions respectively of first and second jaws. The bushing portion of the first jaw is threaded and the hitch pin has a threaded end received therein, the pin being operable to move the first jaw towards the second jaw so that the jaws may tightly clamp a drawbar located therebetween.
