hello everyone! i just wanted to know what the technical differences would be between the 440c and 440d. besides the rear frame being longer. any info appreciated. ???
I believe the 440C has around 70HP and the 440D is turbo-charged and has 85HP. I know a fellow who has a good sized logging company in Rangeley, Maine and he told me the 440C was a great machine but the 440D was the worst skidder he ever owned. His opinion was the additional horsepower was too much for the machine.
My 79 440 c had a turbo.
yea, all the 440cs ive ever seen were turbo. anything after a b model is im pretty sure. only the a and 340d werent turbo.

the frames and body are.. the transmissions arent the same and i think the 540 axles are bigger like 640?
