Preface
This book has been written to meet the requirement of students getting knowledge
in Agricultural Engineering and Farm Machinery and Power Engineering. A
need has felt for a book on this subject of basic standards. A keen attempt has
been made to make the book useful and interesting. Leaving all the unnecessary
things only the essential facts and concepts have been discussed in this book.
It has a direct link with all the concepts in the farm machinery and power
engineering that all the common and complicated concepts have been explained
very short and clearly. It has been experienced that many students lack in their
confidence to face examinations, therefore this book has been written in such
way that it may equip the students with basic knowledge to face examinations.
This book is prepared by keeping the ARS-NET syllabus of Farm Power and
Machinery discipline in mind and it contains excellent collection of important
points on farm machinery, farm power, ergonomics, theory of machines, energy
in agriculture, instrumentation and workshop technology tomeet requirements
of students. The book should serve as a useful resource to the agricultural
engineering and farm machinery and power engineering students appearing for
various competitive exams such as ICAR JRF/SRF, NET,ARS and GATE etc.
The book contains a section on key notes related to important terms on farm
machinery and power engineering. It is useful for better understanding of this
subject. The authors are deeply thankful to individuals, who helped on time for
preparing this book.
It is hoped that this book will be useful for all the students of agricultural
engineering as well as farm machinery and power engineering.
Any suggestions towards its further improvement will be thankfully
acknowledged and incorporated in the next edition.
