Very interesting! Im wondering if A-C didn't see that sheet metal design and copied it for the N series Gleaners?
Im not surprised at seeing John Deere testing a rotary design years ago. Im betting there were a lot more prototype rotaries painted green until they release their "STS" combines.
Rotary combines go back as far as the 20s. Curtis Baldwin was working with rotary designs through the years including one that I recall being named a "Savage" combine. Cant remember for sure on the name. There were other rotary machines built by small companies as well.
John Deere wasn't the only one working with CVT transmissions. White had one designed, their biggest problem was dealing with keeping the transmission from slowing down too fast if the operator pulled too quickly on the lever. IH were well known for having a CVT that they dubbed the "Mechanical Hydro" that they were working on in the 60s until they closed. Before Case took over IH had it slated to come out in 1988 but Case scrapped it.
One interesting thing AC had was in the 40s they had designed a 5 speed power shift transmission that was mechanically engaging instead of hydraulic like the power shifts turned out.
I had the opportunity to speak with the engineer who took the round baler designed and built by Ummo Luebben and built the AC Roto Baler. He told me that John Deere and IH had prototype round balers in the 50s. I have seen the patent drawings of the IH one, would love to see pictures of those two machines.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
