Here are a few pics of the plow and discs. I think one of the landslides (I think you call them) is a little bent. Also one of the disks is broken. In one picture you can see how worn down the shares are.

No problem with the landslide. a slight bend is not going to bother it. The shares from that plow are avialable like I mentioned earlier. The disc may be avail. check with a New Holland dealer. They may be able to order it if it is still available.
I just came across this thread and seen you were able to obtain plowshares for your Ferguson AO plow. Will you please share with me where they are available and part numbers? I was plowing my garden a couple weeks ago with a 3 bottom Ferguson AO plow that I am borrowing and hit a buried cinder block. The front plowshare point now has a huge crack and I'd like to get it replaced.
