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.
