We are running an 07 7010 and an 08 7010 in durum, barley, peas and lentils. So far both combines have been breaking the veins that are on the top of the cylinder about 1.5-2 feet ahead o the chopper. These then go through the chopper and even though they are pretty heavy steal, get all smashed up by the chopper blades. The veins show signs of extreme heat and it looks like they are breaking off where they bolt on to the cylinder. Has anybody else had this problem? The conditions have been somewhat tough, but not that bad and there isn't that much material going through the machine. So far we've gone through 7 veins between the two combines. Any help or insight would be great. Thanks.
