Yep still have the pipes that slid through the cast bathtub that were part of the Oliver Cultivators on a Super 77 a few bits and pieces but most of the rest of them are gone.

I used the pipe to support the front end when I swapped to the wide front.

Never saw them on and complete (before my time) but heard it was a big job to get them on and all put together. It was also the reason Char Lynn power steering was added to this Super 77 because of all the extra weight. It was also the reason a second Super 77 eventually came because the cultivators were in the way at hay making time and was too much hassle to take off and on.

This pic was before the 2nd Super was bought as you can see the pipe sticking through the frame.

I would think a pipe through the frame  style would work with the wide front as it sits pretty far forward as long as the wheels were at the right row width.
