One heck of a workshop project - Bi Rotor Combine

[Hooby Farmer]

Im sure this has been covered on here before i was just getting combine videos up for Dad on the Ipad as hes stuck in the house atm. Heck im impressed with this, some clever guys. A 17 year long workshop project and end up with a pretty cool combine. Dare i say it, it looks a pretty simple threshing design.

have come across this before - looks a great concept

so why another 10years on is it not a commercial reality ?

 

[Hooby Farmer]

I think John Deere bought idea and sat on it, is it not more like 20 years?

I had herd John deere bought the idea and was going to pay the designer for everyone that was sold

 

[Zebbedee]

Looks a brilliant designed machine, really like the way the whole insides come out the front. I hope the designers got paid well?

As said, John Deere bought the patent and shelved it. It was way ahead of its time even as a prototype.

You can see features like the tracks etc that are now in modern machines. The potential with that machine was enormous, look at how simple and modular it is. Some speculate that JDs bullet rotor was based on the bi rotor. I have seen JD prototypes with the paddle unloading system.

It really shows the difference between a farmer engineered design vs a trained engineer design. The rumor we heard is that mark underwood still has the prototype at his farm. A couple friends and I were going to go visit him but never got around to it.

Bizarre why it hasn't been commercialised. Patent will run out in about 20 years from filing. Maybe that's what they're waiting for....

So they don't have to pay royalties ?

Mark Underwood the Bi-rotor inventor died earlier this year. His prototype was up for sale.

Check out the Rostelmash RT 490. That uses a contra rotating concave . It is also sold in the US as a Versatile. I think Versatile own or have an interest in Rostemash in Russia.
James Hunt Of JPM the Versatile importer in Lincolnshire was supposed to be importing them for the 2016 harvest but I have never heard of one working in the UK.

That's a shame I'm sure he would of loved to see it commercially available it looked a well thought out machine

Way ahead of its time!

Fascinating

Sh it, I missed that. Wonder who is/was buying the prototype?

 

[Bushmog]

What a fantastic home project. Great idea, would love to see it in production, so many possibilities to do more with it.

Think its still going up for auction. Have a look on the bi-rotor facebook page for more details.

This is awesome. Why the hell isnt this in production? If jd do own this, why didn't/haven't they produced a machine. They could monopolise harvest. That'll increase their margins.

Both prototypes are selling. It’s only about six hours away, I’m going to try and go.

Hope they find some sort of a home, rather than cut up for scrap.

Gould you put it back into use if you bought one or both of them?
