I just bought a clean JD F620 ZT to ship to Hawaii and don't have a parts manual for it. Any suggestions? All parts will have to be ordered as no dealer around. Anyone have any thoughts on the F620? It has less than 700 hrs on it and looks clean, runs great. Only has a 20 hp Kohler engine and a 52"deck. I have a spare 25 hp Kohler and assume it will bolt up easily? Any thoughts?
