Combines hillside rattle chains do the workIJ

We tried some but didn't see a measurable amount of difference. HOWEVER, we always ran a 25-30 tooth threser tooth drive sprocket, raised the metal curtain, and used chaffer levelers over the raddles as well as the shoe. These were the things that made a difference. Prevention of sliding of grain over raddle might help some but when on a hillside grain falls straight to the middle of the earth. This means it usually doesn't hit the middle to outside part of the shoe either. Thus the invention of accelerator rolls.

I am curious as to where the original idea came from for the accelerator rolls. A few years ago I got mixed up with an amateur wine grower. One of the devices he had for crushing the grapes was almost identical to the accelerator roll design. Is there any connectionIJ

Gleaner patented the accellerator rolls back in the early 70's best I can remember. The actual idea and concept of inertial cleaning is very old in the cleaning industry, no one thought to put it on the actual harvester until Gleaner. The idea came because Gleaner had engineering exercises going of a lARGE conventional combine. Two engines. In fact is was so big we couldn't haul it. It had a steering wheel on the back and the customer would drive it backwards down the road. Not, I repeat not a good concept and gosh did the thing look awkward. Back at the drawing board the goal was this = get more capacity in a smaller package. Result, the N series with power separation and high inertial cleaning. Throwing seed 4 times faster than freefall at a 15 degree forward tilt right into the air blast yielded the needed capacity from a transportable platform.

Tbran; Are you talking about the experimental model 635. That is one huge machine from what I heard. Sure would be nice to see it up front. I don't think the 40mph road gear is for me though!
