Found a plough...finally...and a double disc. They were on Kijiji, so I sent an e-mail.
Turned out to be Massey Driver who is selling them. I'm driving out there this morning...going to start making noise to wake the wife up right after this post.
I'm all excited because I get to meet another member here. I'm less excited about the equipment because it's going to be at least two weeks before I can try them out...we still have snow on the ground, and the frost is deep. Still though, I've been looking for a plough for a very long time.
Updates to follow.
