This book transforms the ICAR-aligned 8-unit syllabus of Farm Power and Machinery into a concise, high-yield, and examination-focused resource. Designed for undergraduate students, competitive examinations, and university assessments, it simplifies fundamental concepts through clear explanations, comparison tables, flowcharts, solved numericals, and objective practice questions.

Beginning with forms of energy and the role of tractors and power tillers in modern agriculture, the book systematically covers internal combustion engines, including SI and CI engines, two-stroke and four-stroke cycles, fuel systems, cooling and lubrication mechanisms, transmission systems, and power take-off operations. Important numericals on power, torque, brake specific fuel consumption, and efficiencies are presented with step-by-step solutions and shortcuts.

The tillage section explains objectives, draft requirements, and the selection and adjustment of primary and secondary tillage implements such as mouldboard ploughs, disc ploughs, rotary tillers, cultivators, harrows, levellers, ridgers, and post-hole diggers. Planting and transplanting chapters compare seed metering mechanisms, potato and small-seed planters, nursery sowing devices, vegetable transplanters, and plastic mulch with drip-laying technologies.

Special emphasis is given to intercultural operations and plant protection equipment, including manual and tractor-mounted sprayers, boom and gun sprayers, aeroblast and electrostatic sprayers, calibration procedures, nozzle selection, droplet spectrum, and troubleshooting techniques. A dedicated unit on safety covers personal protective equipment (PPE), machine guards, rollover protective structures (ROPS), ergonomics, and safe operation of orchard machinery. The harvesting section includes potato diggers, fruit-pluckers, seed extraction devices, and lawn mowers.

Scoring Aids Included
• One-page revision charts and power-flow diagrams
• Tillage selection matrices and nozzle–crop matching tables
• Solved numericals on drawbar power, unit draft, field capacity, field efficiency, slip, and application rate
• Calibration and pre-operation checklists with safety lockout procedures
• Unit-wise MCQs (single-best answer and numerical), Assertion–Reason, Match-the-Pairs, and Short Answer Questions with answer keys and explanations

Built exactly on the prescribed syllabus, this book serves as a quick-revision companion and an effective tool for scoring success in university examinations, ICAR, State Agricultural University examinations, and various agricultural engineering competitive tests.
