Ok this is a question from a childhood memory. The farmer across the way had a tractor with adjustable rears that you could widen or narrow by releasing the hub and either pulling forward or backing up. Can anyone tell me what make etc this would have been? I thought it was an Oliver but I really can;t remember! :?

My ford has power adjust rims. They have 4 plates with grooves welded in the rim. The center hub works like a screw inside them.

I was thinking that AC was first with spin out wheels but not 100% sure. I've had WD , WD45 and a Int. 350 utility with those type wheels.....mike

PAVT. wheels, or Power Adjustable Variable Track wheels, they are known as over here. They were always an "Optional Extra" on new tractors, and could have been ordered on almost any make. I have them fitted to my Fiat, they have heavy Cast Centres,but I never use them to adjust the track width.
I think they were fitted as standard to the MF,178 and maybe the 188.They do seem to have been used a lot earlier on your side of the water.

Here's what the tracks on the Ford Power Adjust rims look like. There are 4 sections like this.
You can see the center hub as well.

Here's the old rim. We cut the tracks out and welded them in a new rim (pictured above)

That's interesting Ron. I don't recall seeing them before. :oops: Guess I'm gonna have to pay closer attention.
When we get moved and Gary comes out here, you'll have to tag along and check them out :cool:

Was that Ford design or yours?

Thanks. Now I know to watch those old fords. All the Fords at the auction today didn't have anything like that.
