I am having trouble plugging the back of the concaves and the front of the separator grates when cutting corn and Milo. We have tried putting in longer agitator pins in the separator area of the rotor and that help in corn at the cost of breaking up the cob. Also we installed pins in the threshing area also. I have also a TR 99 running in the same field it does not share this problem and is actually out cutting in the CR in Milo. These two machines can run in the same field and the tr will do a good job all day long. The Cr's performance will decline as things begin to plug. At the end of the day the tr's Concaves and Separator grates will be clean. The territory man and the factory engineers say I am the only one with this problem. IS this true? Has anyone else had this problem?
