The book covers numerical aspects of Farm Power and Farm Machinery as a whole which will be beneficial to the students of B.E./B.Tech. (Agricultural Engineering), M.E./M.Tech. (Farm Machinery and Power Engineering). This will be also helpful to the under graduate students of agriculture and horticulture with polytechnic courses of agricultural engineering, agriculture and horticulture subjects running in the different SAU’S. In this book numerous solved examples of all the major sub-topics of Farm Power & Machinery Engineering subject are given in two main sections (i) Farm Machinery and (ii) Farm Power. Farm machinery is divided into sub-section like useful formulas and equations related to farm machinery, tillage implements, sowing and planting implements, plant protection implements, harvesting and threshing machineries, other farm machineries etc. and Farm power section is also divided into sub-sections like useful formulas and equations related to farm power, engine power, transmission system, engine components, tractors, other sources of power etc
