Cant figure out whats goin on as soon as it gets a little tough it rumbles like heck sounds like comin from the front of rotor. Could there be something wrong in the rock trap feeder house area to cause this bearing all good. Been doin it for 2000 acres now if cant figure it out will have to swap out the rotor again after harvest. Been a $5000 waste of money.

minnesotaboy our machine does have the high speed sprocket on the rock trap will that make a big difference in tough wheat to go with the slow speed sprocket? We are wet now so will change but could be a few days to try it. Anyone know if could cause the problem?

I was just thinking of you last night. Its getting wet and tough early here and we were grinding on some oats. I was wondering how you made out but it doesn't sound good. On my 1680, I had serrated beater bars and it seemed to be a little better. We never had luck running the slower sprocket, always the fast one. The 8010's aren't much better at feeding either. On oat swaths I can plug up the front end at will. Seems to be in the beater, maybe another 30 yrs they'll be able to feed tough straw.

We cant figure it out maker of the rotor swears it not the problem that it must be in the feeder house but we cant find anything will have to pull apart after harvest but still have 1200 acres to go.

check the piece of angle-iron wear plate on rear side of rock trap, when they get worn through they get a razor edge that really hangs up feeding, part #1320278C1 for 80-88, #1320279C1 for 40-66

Just an idea

I have been following this. You say all you changed was the rotor and the problem appeared, so I would think it's not the feeder. Rumble is a sign of the material staying in the rotor area too long. Have you checked the condition of the vanes in the cage and cone, if they are worn and the rotor being new it could cause what you describe. The Harvest rotor has all straight rasp bars on it in a helical pattern yes, but it will rumble more when it gets tough than an afx/or specialty rotor.
Straight bars were added to a specialty rotor to keep the material in the rotor longer, each set of bars would add 1-1.5 revolutions to the crop in the rotor and two sets can be installed. The Harvest rotor will keep the material in the machine longer as it is all straight bars and in tough-damp conditions it will show.
I think the Harvest rotor was developed in western Canada and the conditions are dry (low humidity) and not too many green stem soys grown there either.
If you install a set of disrupters in the grate area it help your problem. Your into it for $5000.00 so what is another $500.00.

I know this is an old post but I wanted to know if this was solved, or was it wraping on the front of the rotor because of not the right clearence between front bearing housing and the rotor ears.

Finally!!!! Someone else that understands the importance of that clearence. Kile now offers a sharpened knife for the front of his flights. I think there is a sharpened knife offered by a company in eugene oregon as well, but it is for the standard impellers which are loosing favor.

Since you seem to have studied the issues of the transition a bit and understand the importance of certain things in tough running, here's a thread with pictures of a few goodies I tryed this year if you are interested. http://talk.newagtalk.com/forums/thread-view.asp?tid=62424&mid=439631#M439631

I have a ton more pics of the sharpened knife set up close to the kidney. It is amazing the difference it can make.

We had early1460 an small keystock pieces on floor below beater would get bent down an there would be a hump material would have to go over causing poor feeding.kEYSTOCK was above box that collected stones.
