There is a noticeable difference in the width between the two tractors.

Since the H1 is a '72, it will have a heavier and wider axle then the 1970.

Are you referring to the diameter of the axle spindles? Or something else?

In 1972, the diameter of the front axle spindles on the 140 (120 had already been discontinued) was increased to 1".

???? Can't quite see that from the photo. But if so, I might suspect that the 120 has had its axle replaced by a 110/112 axle? I have never seen any mention of a narrower front track on the 120.

So you're saying I have a Frankenstein tractor?

Did you actually take a tape and measure the track width ?

From the pictures it looks like the one on the right has a longer axle casting, but the tire is also much closer the end of it.
The one on the left seems to have the shorter axle casting but the tire is further away.
Seems like the camber angle of the spindle might be different as well.

The one on the left looks (to me ) to have more angle .
The distance from the frame to the tires looks about the same to me.
Get a tape measure

I put my foot between the frame and the spindle , on the 120 my foot was on top of the spindle and the 140 it touched the inside edge.

The one where your foot was on the spindle - look how much further from the spindle the tire is.

Get a tape measure and measure outside of tire to outside of tire.

This is what I was getting at. Yes, the difference from the tractor to the top of the spindle does look different. But the distance from the tractor to the edge of the wheel rim looks the same to me. It appears that when they beefed up the spindle, they also changed the camber angle, making the axle appear wider but the track width remains the same.

It's interesting. Maybe they made the front stance wider in the later years when they beefed up the axle spindles? This would probably be advantageous for stability with an FEL.

Or????
