Why Go from an E to a K?
The new 580 is designated 580K because Case has used the letters F, G, and H on its internationally produced 580 loader/backhoes. (The 580F and 580G are made in France, the 580H in Brazil.)
The letters I and J are not used in the construction industry because of a precedent set many years ago to avoid these letters in model designations.
Thus, the new Case 580 becomes a K.
