No comparison on the axels. About 2-3X stronger than a 2588.  Rear axel is over 2x as strong.  I had a 7088,  it's a LOT heaver than a 2588. 1480 is a toy next to it..  I went from a late 1680 to the 7088, night & day difference.   I'm hoping the 9120 is that large of a jump from the 7088.

 I got a little jumpy last fall with the malt barley around getting sprouts in the fields, So  I went larger.
