Having the top link adjusted so an implement is level front to back does make it easier to drop the implement off of a quick hitch. When just the front or rear of an implement is on the ground there is enough of a bind in the quick hitch hooks to keep the 3 point hitch from lowering. On larger tractors this is less of a problem because you can set the 3 point control to lower, get off the tractor, and bump, kick, or nudge the implement to release the binding and the 3 point hitch lowers.
On a BX tractor the 3 point hitch control returns to the neutral position, so if you are bumping, kicking, or nudging the implement the 3 point hitch stays in position. Sometimes you can hold the 3 point lever and reach the implement at the same time, but it is not always easy or enough. I filled the 3 point lever slot in the fender, with foam rubber to help seal up my cab. As a side benefit the 3 point lever wedges in the foam in the down position and stays there until I raise it. This makes it easier to get off the tractor wiggle an implement and have the 3 point with quick hitch lower.
One other thing worth mentioning is the Land Pride QH-05 made for BX tractors is half the weight of most other quick hitches, so less weight to pull the 3 point down when disconnecting and implement. I am just noting the weight and not suggesting you buy a heavier quick hitch. If you have to take the quick hitch off occasionally its easier to lift off a 35# quick hitch than a 70# quick hitch.
