Реферат: ABSTRACT OF THE DISCLOSURE A trailer hitch has a boom which is slideable from a drawn in position to different extended positions and which independently of its extendability is swingable from a centered position to different sideways angled hook up positions. The trailer hitch is hand operated to pull the boom inwardly from any one of the different extended positions to the drawn in position with a manual pusher for pushing the boom towards the centered position. It further includes safety stops for preventing any outward swinging of the boom while the boom is being drawn inwardly.
