The auger hieght is supposed to be adjusted when raised so that it clears at all times. Yes the frame does flex some when raised. I think if it still rubs then the head may be flexing too much. Quite a few years back NH had this happen on 973 heads and the came out with a reinforcing kit that was welded onto the top frame bar. Your dealer should send your problem in to CNH on their computer system. If there is a frame problem then the company needs to know what serial numbers were affected. I have not heard of this happening on any 73C or 74C heads around my area. I don't know what can help you in the short term but someone has to tell the company whats happening for them to get it fixed.
