This complete guide presents the origins and mechanical principles of farm motors, beginning with a fascinating lesson on “the animal as a motor”, where we learn how the consumption of food results in the production of carbon dioxide and other products of combustion. These products, in turn, result in mechanical energy. From there we are given an accessible and fully illustrated tutorial on energy and its sources, including the law of transformation of energy, primer movers, and much more. Also included are clear explanations on the mechanics of most types of farm motors, with complete information on their construction. This book will give you a guided tour of the legacy of an industry that continues to sustain the American farmer. Mechanics, farmers, and the casual reader alike will all benefit from this one.
