We have a 5 shank CaseIH 2500 inline ripper and in our heavy clay dirt it stops our 340 Magnum with duals all around and full weight package, at the ripper is only 10" deep. Does the same with the 7 shank 870 I borrowed from the neighbor. I am certain that it these conditions, it pays to rip the fields every few years.
