so really that warning should read.
dont worry about the implement you have on the back designed to do what your doing with it. but remember to wear your seat belt like you should be doing because if you hit an immovable object your tractor WILL come to a sudden stop.
In my case with the subsoiler i use, I generally run my tractor at its traction limit so im hardly moveing pulling it through the ground... so the idea of "stoping quickly" doesnt really exist.
Exactly. Pulled 800ft of water pipe using the subsoiler referenced in this thread. Granite, Oak and a bit of clay. I had no problems...but then as you described, I didn't go fast. When I ran into boulders or roots, I stopped. Nothing broken.
