Passed the course... About half sick of looking at computers! But I promised pics so here is the best one I could find. I know I've taken more...
Anyway, my skidding or trailering or sledding would be downhill across the picture, about where that butternut log is laying - getting that beauty down with only dollys and a rope haul was a riot...

We did cut it into 2 big pieces and one small, but it's 22" in diameter, and 10' of that is no joke. Made some beautiful lumber, though.
It's actually just a little steeper up above, and to the right of the picture you can see the final slope down into my yard is a little steeper as well. But mosyt of it is in more or less of a trough. The house is situated in the cut off to the right, so the consequences of something getting away from me involve "all of the above" -my life, my tractor, our home!
The place I've been working in is down to the right, not visible in this pic, and mostly not as steep.
And
1bush2hog, welcome to the thread! That's a fantastic avatar. I too have often come upon helpful threads, glad this one has helped you. Be careful! I like the idea of "bumpers," let's see what the others think.
john_bud, I already have the rears swapped for a wider stance - should I (could I) get them any wider? Do they make spacers, or something?
I'm figuring on antifreeze wheel fill, should I consider wheel weights as well? I imagine there's a point of diminishing return.. I probably better trundle off to check other threads, I'm kinda taking us of-course here...
But thanks all, this thread's a "keeper!"
