First, what is that thing over the hood? Any ideas?
Next, what kind of front grader blade is mounted on it?
Is that a homemade belly mounted grader blade or added weight (ballast)?
Is that hose between the air intake tube and the crankcase breather cap serve a purpose???
Does the arm that appears to attach to the left side rock shaft connect to the front blade?
What else can you find that doesn't belong?

I found this Cub on E-Bay:
