I have a '01 2388 with a 1020 head and went to cut a bit of wheat today and it would bunch up in the header, right in front of the feeder drum! First off the wheat straw is a bit green, but it did this to me last year in the middle of harvest and I thought i had fixed the problem. I had a ploy skid liner in the bottom of the feeder house and the crop had a two inch climb to go up, so I took out the ploy skid out and thought that would fix it. The combine has field tracker on the feeder house and a rock drum in the feeder. The drum is adjusted all the way to the highest position. On the header, the wheat is not wrapping around the auger, I have the stripper bars all the way out but not rubbing, but when it gets to the feeder it justs bunches up on top of the auger in front of the feeder drum. After that happens nothing will feed in. Any help or advice is much appreciated!!!
