I just purchased a 1974 Case 220 tractor. It has a mower deck and snow blower with it. The engine has been changed from the original Kohler 10 horse to a Kohler 12 horse. The tractor seems to be in good condition so I would like to restore it. Can anyone tell me the best place to get owner and service manuals and to buy any parts or decals I may need for it? Thanks.
