The Book “Repair and Maintenance of Tractors and Power Tillers” is a comprehensive guide dedicated to the upkeep, troubleshooting, and servicing of two of the most essential machines in modern agriculture. As mechanization continues to transform Indian farming, tractors and power tillers play a pivotal role in reducing manual labor and boosting productivity. This book provides practical knowledge on maintaining their performance through routine servicing, fault diagnosis, engine overhauling, transmission and fuel system repairs, and electrical and hydraulic maintenance.

Designed for farmers, students, technicians, and agricultural engineers, the book presents content in a clear, structured format with step-by-step instructions, illustrations, case studies, and real-world examples. It also explores emerging technologies such as electronic fuel injection systems, smart diagnostics, and automation in farm machinery maintenance. Emphasizing preventive care and safety, this book equips readers with the skills to extend machinery lifespan and enhance operational efficiency, making it a valuable resource in the agricultural machinery sector.
