"WORKHORSES" OF DAYS GONE BY

On my last trip to our local salvage yard with my hubby, I spotted these very old tractors that had obviously been sitting there for a long time.  Growing up on a farm where there were always tractors I was thinking about the work these pieces of machinery did, the farmers who drove them, etc.  The upper one is an old Case but I was unable to find anything on the other one to indicate its make.  Memories!
