We have a F30 with 400 series hookups on our 575R. The header floor steps down into the feed house. In other words, the grain feeding into the feed house has to take a step down. It's as if the header is trying to feed the grain into the middle of the feed house chain front drum. If we bleed oil out of the correct fitting on the right side tilt cylinder we can lower the header relative to the feed house but once we tilt the header enough during operation the cylinders return to normal. Someone told us they had the ability to do that from the cab. Did we understand them correctly?
