Yes they mean the same thing...What do you mean by "...option the tractor out with over size drive lines?" (or "spec'ing their tractors with heavier drive lines for heavy pulling," I assume you meant the same thing with both phrases.)
When you are going to be pulling extra heavy loads over and over, (like pulling pans) they (mfg.) spec. the tractor with larger axles and other parts all through the drive line. It's done for a reason and that is, they have too many drive line failures of std. tractors pulling those same loads...
IF you have stumps small enough to put your tractor in gear and it pulls the stump right out, that's one thing... BUT, that rarely happens, so it's a lot of backing up and moving around for more traction, and that's puts a huge stress on the entire drive line.
Eventually, you WILL find the weak link, and the ring/pinion is the weak link many times... All it takes is to chip a tooth this time, and then the failure can and will come later, probably when you aren't abusing the drive line, and then comes the part where the owner says, "I was just " " (you fill in the blank) and the rear end let go...
Like I already said above, I've seen this quite a few times, and some of those folks come here with similar stories...
