Fixed it:)  The throwout roller arm spring whae broken and the bolt stud bolt for the mesh dog was rusted solid to the housing.  Replaced the spring, and then did general clean up of old grease/dirt.  Took the stud bolt out and used emry to get the rust off, reassembled and it works like a charm.  thanks for the replies and advice.  I believe that I have a 212 or 214 gang plow as it looks identical to the pictures I have seen.  thanks again.
