A trailer hitch assembly better secures a trailer to a vehicle trailer hitch. By restricting vertical travel of the trailer coupling, a hitch ball on a draw bar is better engaged by the trailer coupling as any vertical dislodgement of the trailer coupling from the hitch ball is restricted by the underlying trailer hitch assembly. The underlying trailer hitch assembly cannot travel upward when locked into position as the draw bar obstructs its upward travel, thus preventing the trailer coupling from disengaging the hitch ball. The trailer hitch assembly is lockably pivotable away from the underside of the draw bar in order to allow controlled disengagement of the trailer coupling from the hitch ball. The trailer hitch assembly may act as a support when placed in the vertical or downward position with a wheel, pad, or skid providing support for the accompanying trailer and its load. Additionally, a new trailer hitch ball system is detachably attachable to the draw bar without a shank, nut, or washer.
