Hi, I have a bobcat which I thought was a m600 or M610 was but now I saw on the forum that there is a Wisconsin VF4D engine is in the bobcat. Now I looked at the motor in my bocat and I saw that it was a KHD Deutz engine in it. can beat or has anyone ever put in a different engine? sorry for my bad english (google translate) here is a picture of my bocat: http://tinypic.com/r/70ukwl/5
