Hi: Had the same problem with my 98 R72,easiest fix we found is to raise hight of paddles. I have oversized rubber on the back so I had to cut the paddle lenght all the way back to the pan. I then bolted on a pieces of poly 8 in. high rounded off to the centre shaft. I had to backoff angle on two paddles because straw was now landing in the wheat on the right hand side. The pattern is now centre over a 22 ft.swath, not perfect but better than I ever did with original equipment. Goodluck Hald.
