Just checked out the Prototype section of this site, got some cool new additions since last time i saw it!
If I remember correctly the BiRotor rights were purchased by JohnDeere and later appeared as the CTS system.
I think there was a book written about this called the "Dream Reaper", anybody read it?
I could also be way wrong here, anybody know better?

Laapa, Deere did buy the rights to the BiRotor.
From what I have heard, Deere bought it to keep the competition from having it.
I don't know if they used any ideas from it for the STS or CTS.
There was talk about it on another board, but it was awhile back. I will check if it is in the archives.

Seems to me someone claimed it had some trouble in conditions like those associated with high moisture corn. I'm not sure if that's correct. Too bad it hasn't been put into production. It was first built on an IH axial I think and later in the pictured version with tracks and conveyor unloader etc. Cat was interested, but John Deere got it. Some are still wondering if it will reappear someday in Deere's line.

Additional comment: "Farm Show" used to have a video on it. Don't know if it's still avaliable. My understanding of the concept was that the outer grate would roate slowly in the opposite direction to the central rotor using the whole surface of the grate for separation. Interestingly, one could leave it attatched to header take out some bolts or pins and back the combine out from around the rotor leaving it exposed and attatched to header for maintenance and repair. It replaced augers with a conveyor system. I don't know if any features have been used in the later John Deere designs. Some claim the STS is based Massey's old design before they bought the White rotor design in 85.

Well, guess I was wrong as far as the BiRotor being the CTS.
Don't know where I got that from. Well, the BiRotor name and JD purchase sort of suggest CTS don't it.

The name would suggest the CTS, Laapa. That would be the logical assumption since there really hasn't been alot said about the birotor.
"Farm Journal" had an article on it when the concept was still in a white painted IH rotary. If I remember correctly, it was invented by some brothers and their friends in Kansas. They were trying to make a combine that was more cost effective and less expensive for the farmer. I'll bet they're pretty disappointed that it hasn't been produced yet.
Another concept I wonder about seeing again is the twin rotor Versatile with somewhat conventional cylinder that was produced in a pull type in Canada. I wonder if the concept or part of it will be part of a New Holland combine some day.

Red_Painter, have you seen the selfpropelled prototype of the Versatile combine, claimed to be the biggest in the world at the time!

No, Laapa, I never heard of it until I saw it on the combine photos of Today's tractors. Do you know anything more about it? I don't know anything about it. I assume it's based on the pull type used on the Prairies.If I remember right that machine, had a somewhat conventional cylinder that moved the crop a little sideways until it could be unloaded onto the rotors. Seems that it may have had some similarities in the front cylinder to the New Hollland TF rotor. It must have had great capacity. If anyone hasn't seen the picture of it, it's on www.ytmag.com/cgi-bin/today/cphoto_view.cgi and click on Versatile 4wd Trans/axial combine |
