I could not agree more on all the reasons for the DK, I have been a very satisfied CK 30 HST owner for two years and I just upgraded today to the DK 40 HST. Everything I noticed while operating the CK 30 that could be increased or accomplished in a better way is done on the DK. More power, more lift capacity, larger bucket, ease of walk through on the deck, convenience of controls, tougher under carriage and the list goes on. I've also had terrific dealer support.
