Bi-Rotor in new Versatile?????????

[wheaty75]

Versatile rep says concave will move around the rotor. Sound like anything discussed on here before.

Nope.

My Versy rep has very tight lips on this subject... Even though I saw one slugging around the field near Patricia, AB (Dinosaur park).

Are you meaning the concaves drive around the rotor(s) ?
Yikes.......

Yes very much like the Bi-Rotor concept developed by Mark Underwood.

[blackdirtfarmer]

I beleive you are referring to the Rostselmalsh Torum 740......... rotating rotor cage to help clean out the concaves....... They are sold over seas right now.

Is that a feeder beater at the begining of the threashing system in that pic?

[Christian A. Herrnboeck]

yes... more than one It's a hybrid type system much like a lexion, but with 1 seperation rotor and the concaves moving counter to the rotor movement.

[kirschenman]

Doesn't look like there is any concave under the last beater in the diagrams.

Underwood's system is "co-rotational", meaning that the concave rotates the same direction, but slower than, the rotor.

The import combine calls their system a "contra revolving" concave and drum. Meaning opposite rotation from the rotor.

Cool. I think my old L2 would smile to see a feeder beater on a new combine.

I remember that Mark underwood tried the counter rotation first, but it wasn't nearly as good as co rotational. It makes a lot more logistical sense to be co-rotational. I don't see much gain in moving opposite directions.
