I hope someone can give me information about my snow thrower. It is an International Cadet 268. It has n 8 hp Briggs & Stratton engine and a 26" wide cutting width. Picked this up a few years ago from a guy who slipped and fell while using and the machine walked across the road from him and stopped when it hit the curb on the other side (auger and wheels still turning). So old it has a hand clutch with no safety shut offs. Thing runs great, but just would like to know how old and have a copy of owners manual for it.
