I finished welding the lift pins onto my modified 3 point Brinley disk (now potato hiller/ raised bed maker) I can't wait until it dries up enough to try it out. the disks are totally adjustable and I might have to take a couple of the disks off we will see how it does.
It has been too wet to try it out. It might work better if I take 2 outer disks off each side, will wait to try out and see. If it doesn't work to suit me I can flip the disks around and re-adjust and just have a 3 point disk. It would be better than a drag anyways because I can use the down pressure of my tractor and not have to use weights on it.
