I should have put something else in the photo for scale. It's about 5" high.

It's either some kind of a shoulder bolt or a leaf spring bolt with a bushing frozen on it???

That's a large shoulder bolt.
5" long. so approx 2" shoulder diameter.
So what's it for?
A simple bearing surface for slow moving rotation. Imagine a flat plate just slightly thinner than the larger diameter of the bolt is long. Now drop a washer on the bolt, lower the hole in the plate over the bolt, then a second washer. Add spacer, and nut and torque to spec.
Simple rotating joint. Lube frequently, rotate slowly. There'd be a dozen or more similar bolts of all diameters on an old tractor.
Could be 100 years old….or 30.
Doesn't Russ know? And what did you do to him to deserve this nutty reward?

It's part of an early wide crack protection device.

Okay, okay, you guys. I'm more interested in knowing whether you know the history of this bolt. It is a piece of climbing history and it's NOT from the Dolt cart.

I've got one on my 12 year old tractor. It looks about as rusted, but this is Alabama.

looks like there have been ropes pulled around it at some time, you can see a shiny patch on the right side at the top part of the thickest un-threaded cylinder as well as a rope-thick sort of stain all around that part of the cylinder and tilted at an angle you might expext if this thing was used as a rap anchor at one time. Turn it upside down and that's probably how it was placed in the field. But where and when? you've got me. I've never rapped off that sucker.

Yup, Little Z, it was used as a rap anchor on occasion. Also as a belay anchor. It was embedded threaded end first. But where?

Arrow tip? Seems like a likely place for that way back when.

Cragman, might have been, but that's not where it spent upwards of 50+ years of it's life until Russ acquired it.
