Is there anyway to improve the rocktrap on a Flagship machine? I have owned a couple of Flagship machines and the rocktrap sucks. May be only stops 1 or 2 rocks out of 10. Have owned a 2388 and a 1688 and they would stop 9 out of 10 rocks. I would hate to think what it would be like if I didn't roll my fields. Seems like there design went backwards. Thanks
