the ripper will hold up, my neighbor ripped the 3-point apart on his 2670 Case, he figures he hit a rock and the shear pin was welded. As far as your tractor pulling it, dad had a 5 shank zone builder on his 8430. No hills and good black dirt. It pulled it ok, needed better tires and some weight may have helped. You didnt have enough power to run away with it.
