Is the case 580 d the same as all 580 backhoes maybe 580k
No.
I know from the D model K model are a lot of differences I’m sure you could probably Google it. I’m sure the transmission and hydraulics and probably the motor too just to name a few.I’m sure some of the guy’s on this forum know more detailed differences,good luck!
Pretty vague question. What differences were you looking at?
580D,E and K spot the differences.
