Structure is 2 x 2 x 1/8 steel tubing, 1/4" gussets. The receiver socket is 2.5 x 2.5 x 3/16" (which is a little loose on a 2" stinger). This attachment weighs only 15 lbs.

Welded with 7018 which is kind of like cheating.

Then built the lifter part. The stinger end is 2 x 2 x 3/16. The two lifter prongs are made of 1 x 2 x 1/8". Looks kinda like its asking for abuse.

Havent figured out how to attach the (pulling chains) yet.

Love the build. But wouldn't the Forks be too low to the ground to get good hight for the logs to get off the ground better

How about a pair of tongs that your hydraulic top link could pull tight to bite in and slack off to release?

I have tongs that can go to about 16" but this log is about 20". I will make an adapter for the 16" skidding tongs though, as most of my logs are within their 16" range. Would be fun to grab onto a log without getting off the seat but I'd have to pretend that there's 20 logs all lined up & waiting for me to back up and grab onto. In reality I never have more than a few at a time.

But you're right about using the top link to lift with. Probably the way this will work out is the lifting fork is just used for lifting the log to get a chain under it, and will have to add a small "boom" above with a grab hook and a short chain with a slip hook, then tension/lift by tipping it fwd with the top link. Like the Northern Tool "Log Hog".

That should do it.

I noticed that your log contact points are smooth. You might want to weld a couple of pointy things on each arm so the log isn't as likely to slide off.

This project is still in development,,,,,,, I might do that at a later step.

I've been using the standard log arch but you have to pull pretty straight with those. If the arch is narrow, they tip when you turn especially if there is resistance from the rear of the log. A wide log arch is just a lot more machinery than I want to move around the woods.

What I'm trying to develop is a way to skid logs above the dirt. Sawmilling a log that has dirt in the bark can dull a $20 bandsaw blade in the first cut. There will be a narrow dolly at the rear end, but need a way that the dolly can't tip over on un-even ground, or going over sticks and around turns. So at the front, ultimately I will clamp onto the log letting it swivel left/right and up/down but not rotate (kind of like a U-joint). Will design something compact that I can also use on the ATV for smaller logs. If its a smaller log the ATV can get there faster than the tractor and return faster too.

Here's a pic of whats in my mind. Have to think of a way to lock the u-joint for the lifting function. And find a chain binder that works on a curve :D . The plan is to strap the dolly on upside-down then roll the log over, onto the wheels, then attach at the front and drive away.

I'm trying to make some compact stuff that I can get to the log-site in one trip. Often I want to just move a couple logs and saw them up NOW, not set up for production. And I like to build stuff so I create a special need. With regular needs I could certainly buy regular stuff for cheaper than the time to build it :D .

Even the big guys sometimes have trouble in turns. :)
