Bought a used 2011 9120 with tracks and 4wd last year. I did not have any problems with it. Run 40' Macdon on front and 12 row 38" Geringhoff. Had to cut some double crop beans late last fall on ground you could barely walk across it did not leave much of a rut. We will be starting milo harvest here in 10 days looking forward to getting back in the field.
