If Cat had come out with this I'm sure it would be the best thing since a pocket on a shirt. As for resale , the Deere machines that are hydro now have a relatively high resale comparable to the almighty. I looked at a 650H when I bought my D39 , It had double the hours and was 10k $ higher in price. To me price depends on what a person is willing to pay. A for previous hydro machines , Case a good one in the 1550, they really never took off. Very nimble. I ran one a short period compared to a D6D it was on par. I do know the one I speak of had an issue , the owner repaired it his self , did not do what Case recommended as far as flushing the system. It failed again in 200 hrs. I think it was powered by the 8.3 cummins.
