What are your thoughts on the 3 point log skidding attachment ?
You didn't ask me, but I spent nearly 10 years skidding logs on a 3pt drawbar, before getting a loader big enough to just lift most of them. You've been here long enough that you've probably seen some of the photos I posted of skidding oak and ash logs > 40" diameter, on the back of an old Ford tractor.
My thoughts are, it can work beautifully, depending on the terrain and ground condition. Most of my skidding was out of a deep woods, using an old creek bed, such that I was skidding these logs over a mostly rocky surface. The logs stayed clean, I wasn't doing a ton of ground damage, and it was all good. If anything, it helped with a bit of de-barking.
But it's an awful way to move logs across your lawn, obviously. And on mud, or a field, any deeply-grooved bark is going to pick up a ton of mud and the stones that come with it. Real hell on your chains, if you don't leave them sit long enough to knock the bark off before cutting.
Also, since you almost always want a bit of lift on the front of the log to prevent the fore end from digging in or catching on ground obstacles, you do have to be careful to not wheelie the tractor, if it does manage to catch on something. A sled or arch is obviously much safer, but I did manage to skid nearly 100 cords this way without any major incidents, before my equipment allowed me to change technique.
If you still have that tandem Fergusen in your avatar, I guess going wheelie would be less a concern for you, than those of us driving "regular" machinery.
