Combines Rotor removal on 9860IJ

Those are bad questions to be asking when you just bought the combine. Gg

you need to know that when it eats a rock or auger tooth.

The [not a]rotor is larger diameter in the back,so therefore it needs to be made smaller- teeth removed or whatever before it comes out the front.That is after you remove the feed accelerator_stone beater.Sounds simple enough.Your dealer should be able to answer all your questions.

How much time will all this takeIJ Doesnt sound too difficult but it sure sounds time consuming.

I was informed by John Deere engineers that the entire rotor is built a lot heavier - including fingers. That is a couple of the changes on the 60 series. You should have a lot less to worry about - so they tell me. Also the grain feeds into the top and bottom of the front of the rotor - not just on bottom.

How did the fingers_tines changeIJ Did they change the material away from cast ironIJ Sure hope so; anything less is another slap in the face. P.S. STS rotor removal figure 6-7 hours for average dealer mechanic. Not so easy... remove feeder house, remove tines, remove FAST beater, then remove rotor. Also, the grain does not feed into the top of the rotor. It can't because the rotor bearing plate prevents it. All grain must enter rotor below this plate, just like in a Case. If a JD engineer told you that, it would go a long way in explaining a lot of the, um, design oversights, of the STS.

Harvester, you are right, it does feed BEHIND the bearing plate. The bottom, center, and top of rotor. That's why they call it TriStream feeding which gives more uniform material flow. Are they misleading me and the brochure tooIJ I would like to know. Thanks

Yes, it is very misleading. look at the location of the beater relative to the rotor and the bearing plate. In order for any material to feed into the top of the rotor, it would have to physically jump over the front bearing plate. Maybe they figure those Mexican jumping beans can leap over the plate, but I rather doubt it.

Harvester, Just got done taking a look at my 9860 and took the front top cone cover off. If i look down through the top, i can see the beater. It looked like it has a direct pass that it can put some material to the top of the rotor or so called top of the screw.

The [not a] rotor doesn't get larger in diameter in the back. The outer cage rises in stages so there is more room at the top the further back you go, but the rotor itself is the same diameter its full length. I think they knock the bars and tines so that nothing catches when it comes out. It does take a while....
