Can anyone identify this thing?
 

It's said to be between 2.5' and 3'. Found in a back yard.

Is it attached to anything?
Is it the shut off for the water or gas main?

huh/
 

Looks like an old farm tractor hub. And it looks like it is only about a foot in diameter at the most. Who measured this thing?

I'd say tractor parts is a good guess...

Never saw anything like it used in plumbing...

A lady emailed me with the picture and said some people on another forum thought it was a pump part. Close but no cigar. She apparently measured it, and you know how us guys lie about measurements; so...

I was hoping she would pop in here and answer some of the questions everyone is asking. I sent her links to four Forums where I posted it. Maybe she will show up yet.

To me, it also looks like a part of a tractor i got this picture, these are the parts of a tractor take a look over it and see if it is one of them

Those all look like gears and splined shafts. Someone from another Forum said it looked like a tractor counter weight. That's a possibility. She posted another picture that shows it standing up with a tape measure on it. I'll post that here.

Lets see if I can make it larger somehow. I guess I downloaded a thumbnail.

My guess is road grader, the part above the plow center of grader.

Well, i think you are right, i just googled off with "Tractor counter weight" and i got these images they all looks like the thing you posted in here, take a look over it hope i am not wrong again... :D
