I had one spot on my trail where the road slopes sideways and there was a ravine off that side, and if a big log slipped over it could well pull the tractor over sideways with the lift point high on the 3pt arms. If I had a heavy log behind, I'd just stop shortly before that point on the trail and hook to the lower fixed point and carry on. Most times I wouldn't be pulling anything that would be heavy enough to worry about, but it's something to think about.
