If you're talking about that snot in the upper right corner I think it's just a piece of debris. Looks too 3-dimensional to be a crack...Looks like a pretty healthy stress crack in the neck on the 2nd picture, where the tongue area attaches to the center pivot on the rake where you would rotate the rake to angle it during use, etc.

Something caused the metal to fatigue there and it looks like the crack is nearly 1/2 way through the material. I would have that welded to stop the failure from becoming complete.
