This book turns your 8-unit outline into crisp, exam-ready learning for Farm Power & Machinery. It starts with energy forms and the role of tractors vs power tillers, then builds core IC-engine concepts (SI/CI; 2-stroke/4-stroke; fuel, cooling, lubrication, transmission, PTO) with quick numericals on power, torque, BSFC, efficiency. Tillage is taught the way questions come: objectives → draft → primary vs secondary implements (mouldboard, disc, rotary, offset rotavator; cultivators, harrows, levellers, ridgers, post-hole digger) with adjustment tips and field problems.

Planting/transplanting chapters compare metering mechanisms (fluted roller, plate/cell, pneumatic), potato and small-seed planters, nursery sowing, vegetable transplanters, and plastic mulch + drip laying workflows. Intercultural operations and sprayers (manual, tractor-mounted, boom/gun, aeroblast, electrostatic) include calibration steps, nozzle spacing, droplet spectrum and troubleshooting. Safety gets a full unit—PPE, guards, ROPS, ergonomics—plus orchard tools (shrub cutters, pruners, pick positioners). Harvesting closes with potato diggers, fruit-pluckers, seed extraction, and lawn mowers.

Scoring aids

• One-page charts: power flow (engine → clutch → gearbox → differential → PTO), tillage selection matrix, nozzle–crop match

• Numericals & solved examples: drawbar power, unit draft, field capacity/efficiency, slip, application rate

• Checklists: pre-operation, calibration, safety lockouts

• Unit-wise MCQs (single-best, numerical), Assertion–Reason, Match-the-pairs, and short answers with keys
