The jack foot adjustment device is a tongue jack for a trailer. The jack foot adjustment device provides both a fine height adjustment accessed by a hand cranked and a gross height adjustment accessed by pushing the foot plate of the device with the user's foot. Retracting the foot plate can be accomplished by turning the hand rack in the opposite direction and/or by pulling the release handle and allowing a foot spring to pull up on the lower foot. The fine height adjustment uses a vertical screw turned by the crank to pull or push an upper foot out of or into the body that is coupled to the trailer. The gross height adjustment uses a spring loaded pawl to allow downward movement of a lower foot while preventing upwards movement of the lower foot unless a handle releases the pawl.
