Our '05 4120 has 2 piece rims. But I noticed that the new one xx20's have 1 piece rims. When did Deere change? And why would they do that?
When did the 20 series change to 1 piece rims?

I think the rim change was only with R4's. The R1's still have the 8 position, 2-piece rims.
One reason for the change-over might be - they're a PITA to take off and re-adjust for width. And if you aren't careful when you re-tighten the bolts (cross-hatch pattern) you can get an unbalanced rim that will constantly work loose and need to be re-tightened.
Most users with R4's don't worry about row-crops or orchard use, hay production, etc. so, changing the tire footprint is not a high priority.

Correct, and they are less money too

My dealer told me JD rolled the R4 solid rim change in on the 4X20 models sometime in 2009. So now you have only two choices with R4's -- either very narrow width around 71" or very wide width at around 90". The last I checked the Operators Manuals and sales literature had not yet been updated to reflect the change. When the dealer delivered my new 2010 4320 a few mos ago I was surprised with the new welded one piece wheels. I'm now looking at getting wheel spacers to get out to 78" or 79".
