I have the square drop leg jack as well. Mine is a Fulton. They don't fold back, but are permanently in place. Works great for me. Untill recently I too had considerable grade where the boat was parked and never had a problem with this jack. I do put a brick under the foot for no other reason that to give it a bit more tilt for the rain to run out the bilge and scuppers.
I cannot imagine having to dead lift that tongue off the ball. OR have to move it from that spot to "put it in the back".
