I bought one of those plows a few years back at auction. I got to plow one garden with it before it sold again. No coulters isn't the hot set-up here.
I've been told the wear parts on those plows are the same as Ford 101's. If so, they are easy to get ahold of. Shouldn't be too much worry about wearing it out just yet though, seeing as to how it still has lots of paint to wear off!
