Farm Implements and Machinery is an essential input in agriculture for timely field operations for increasing production and productivity of land. It is used for different type of machinery like tillage, planting, plant protection, harvesting and threshing machinery and irrigation equipment, threshers, sellers, cleaners, graders etc. The better and fuller use of machinery offers an excellent prospects of improvement in this direction. The main concept of this book is to apply the principles of engineering and technology to do the agricultural operations in a better way to increase crop yield. With its application oriented and interdisciplinary approach the book would be immensely useful to scientists, teachers, students, scholars and extension workers dealing with agricultural engineering and agronomy.
