Combines 480 plugging

If your running a chopper I can tell you exactly what happened. Same thing happened to me on my 9600. I was cutting to fast in green straw (still a bit damp.......wheat was ready but the straw was still green) and it plugged up the chopper and it came to the halt and pretty soon the buzzer was going off and I got it stopped before it plugged all the rest of the way back into the walkers. Might not be the same scenario as what happened to you but I know that darn green stem raises havoc in these machines sometimes. Was the wheat you were cutting a bit tad green stemed stillIJ Maybe it was in the evening when humidity was highIJ When that straw get's "rubbery" it don't go through like it's supposed to. Just some thoughts.

I have seen this a few times also. I have tried two things with good results. One being changing rotor speed to a faster speed. This helped a lot in short light wheat conditions. The other being rotor covers that are avaliable through your dealer. My first thought on this was what a pain and capacity would suffer but the new 470R had a solid portion on top of the rotor also.

As best I can tell, the straw seems to hairpin together as it comes out of the rotors, then continues to build up on itself until it completely fills that area. Try using a hoe to dig it out instead. You'll still have to drop the pan and crawl in to get the job done. If there is a cover plate available for that portion of the rotor, you might give it a try.

Robert, this seems to be very common among the lexion rotors. Before we ever started last summer a CAT guy from Australia was with us and urged us to clean this space between the rotors frequently. There is an opening on top of the machine right behing the engine. We just took a big pipe or something and pushed all the straw down about once a week and never had a problem. The new R-series are not supposed to have this built up anymore.
