Farm machinery mechanical devices including tractors and implements are used in farming to save labour. Farm machines include simple hand held implements used since prehistoric times to the complex harvesters of modern mechanized agriculture. For crop production they include handling of residues from previous crops primary and secondary tillage of the soil; fertilizer distribution and application seeding planting and transplanting cultivation pest control harvesting transportation; storage premarketing processing drainage irrigation and erosion control and water conservation. Today the Indian farm machinery industries meet the bulk of the requirement of mechanization inputs and also export. In addition to embodied energy in inputs such as fertilizer energy requirements for agriculture and industry can be divided between demands for shaft power and demands for process heat. Firewood and charcoal can be used to meet these requirements but there are other suitable sources too. This book provides all the relevant information in the field of farm machinery with focus on the basic principle of working systems and devices. This is a good reference book for agriculture and agricultural engineering students. As well as a comprehensive book for practicing engineers specializing in field of farm mechanization.
