It has a shin, but not like the one on my #555 plow. It's narrower and wraps around the side of the bottom. I guess you'd call it a shin. It has replaceable shares.
I figured most people ripped those hitches off years ago. I don't think I've ever seen one before, only heard about them. That's why I thought I'd like to keep it on there. We've got a 555 and a newer F630 plow with trip bottoms for plow days. Thought this little 44 would be good for the potato patch behind the "B". (no rocks there, ha).
Thanks for the response, I didn't realize the parts books were online.
