I have plowed with a 54' NAA with a 2-14 Ferguson plow. We have pretty heavy soil so we can't use a 16".
In order to properly plow, you must have the top link in the very lowest position on the tractor. Then you push the small lever down to draft control. When you push it down and if your implement position control is all the way up, your plow should raise up. The small lever should move about 1/2 to 3/4 of an inch from the draft position to the lift position.
The book recommends 2nd gear but somtimes you have to use 1st. After you are started into the field, let the little lever go and adjust the big lever to the desired depth that you want. You should notice the 2 bottom arms pulling up when the tractor starts to slip. If this doesn't happen, and your tractor spins to a stop, there might be something out of adjustment on the inside.
This is the experience that I have had plowing. It is fun after you get the hang of it!!
