Abstract: A retractable jack foot for a trailer hitch jack is disclosed, for rapidly raising and lowering the tongue of a trailer. The retractable jack foot solves multiple prior art problems discussed above in the “Description of Related Art,” such as: trailer hitch jacks not being long enough to reach the ground and still lift the trailer to a sufficient height (small distance travel); the laborious, time-consuming practice of cranking a trailer hitch jack all the way to the ground before finally causing lift in the trailer. In both cases, blocks of wood or other spacers are sometimes used to reduce the travel of the jack. The retractable jack foot of the present disclosure, solves those problems, by providing a “built in” block, or foot, pivotally attached to the bottom of the trailer hitch jack. The jack foot can be rotated into and out of position as desired, to quickly lengthen or shorten the jack.
