These are on that cultivator I bought from John B. NE IN.
I thought maybe they had to do with a hiller attachment, since I've never
used one, but there are only two of them.
They currently are not hooked to anything, just have what looks about like
pipe niples protruding downward.
There are no threads visible in the top of them to hook anything to the pipe,
so I don't know how you would run fertilizer or anything else through them,
or what the adjustment would do if that were the purpose.
Just looks like it would re-position the pipe.
