Agricultural Mechanics Course

Lesson 1 • Shop Hazard Identification

Teaches recognition of electrical, chemical, mechanical, and fire hazards in the shop. Builds the risk-assessment mindset learners apply throughout the course.

Lesson 2 • Shop Rules and Tool Organisation

Establishes behavioural expectations, housekeeping standards, and tool storage practices. Orderly habits reduce accidents and improve efficiency in all lab sessions.

Lesson 3 • Personal Protective Equipment

Covers selection and proper use of PPE for common shop hazards. Connects to every subsequent hands-on activity by establishing non-negotiable protective habits.

Lesson 1 • Fastening and Gripping Tools

Teaches use of wrenches, pliers, screwdrivers, and hammers for assembly tasks. Proper tool selection prevents fastener damage and ensures secure connections.

Lesson 2 • Cutting and Shaping Hand Tools

Covers proper use of saws, chisels, files, and snips for cutting wood and metal. Correct technique prevents injury and produces accurate cuts for assembly.

Lesson 3 • Tool Maintenance and Care

Covers cleaning, sharpening, and storing hand tools to extend service life. Well-maintained tools improve accuracy and reduce the risk of tool failure.

Lesson 1 • Stationary Shop Equipment

Introduces drill presses, band saws, and bench grinders for precision shop operations. Stationary equipment expands capability beyond what portable tools can achieve.

Lesson 2 • Angle Grinders and Sanders

Teaches wheel selection, guard adjustment, and safe grinding and sanding technique. Correct wheel choice and guard position prevent disc failure and injury.

Lesson 3 • Portable Drills and Drivers

Covers bit selection, speed settings, and drilling technique for wood and metal. Proper setup prevents bit breakage and ensures accurate hole placement.

Lesson 4 • Compressed Air Systems

Covers compressor operation, air tool use, and pneumatic system maintenance. Compressed air tools accelerate many shop tasks and require specific safety practices.

Lesson 1 • Wood Finishing and Preservation

Covers sanding, priming, painting, and sealing wood surfaces for outdoor durability. Proper finishing extends service life and reduces maintenance costs.

Lesson 2 • Lumber Selection and Properties

Covers lumber grades, moisture content, and species selection for structural and finish applications. Choosing correct lumber prevents premature failure in agricultural environments.

Lesson 3 • Wood Joinery Techniques

Covers butt, lap, dado, and mortise-and-tenon joints for structural connections. Joint selection determines the strength and durability of the finished assembly.

Lesson 4 • Fasteners and Hardware for Wood

Introduces nails, screws, bolts, and metal connectors appropriate for agricultural wood structures. Correct fastener selection resists shear, withdrawal, and corrosion.

Lesson 1 • Metal Fastening Without Welding

Covers bolted connections, rivets, and self-tapping screws for joining metal components. Non-welded fastening is essential when welding is impractical or materials are dissimilar.

Lesson 2 • Cutting Metal Stock

Covers cold saw, angle grinder, plasma cutter, and shear use for cutting metal to size. Selecting the right cutting method improves edge quality and reduces finishing time.

Lesson 3 • Metal Layout and Marking

Teaches scribing, centre punching, and template use for accurate metal layout. Precise layout reduces material waste and ensures parts fit correctly after cutting.

Lesson 4 • Metal types and properties

Covers ferrous and non-ferrous metals, their properties, and common agricultural applications. Material knowledge guides correct selection for strength, corrosion resistance, and weldability.

Lesson 1 • MIG welding fundamentals

Teaches wire feed speed, voltage settings, travel angle, and bead technique for MIG welding. MIG is the most common process in agricultural shops due to speed and ease of use.

Lesson 2 • Oxy-acetylene welding and cutting

Introduces gas welding flame types, torch technique, and oxy-fuel cutting for thin metal and pipe. Gas processes remain valuable for heating, bending, and cutting in field repairs.

Lesson 3 • Welding safety and setup

Covers arc flash protection, fume ventilation, fire prevention, and equipment inspection before welding. Safe setup is the prerequisite for every welding operation in this chapter.

Lesson 4 • Stick welding fundamentals

Covers electrode selection, amperage setting, arc length, and rod angle for shielded metal arc welding. Stick welding excels in outdoor and field repair conditions.

Lesson 1 • Carburettor service and adjustment

Covers carburettor disassembly, cleaning, jet inspection, and idle and high-speed adjustment. Proper carburetion ensures correct air-fuel mixture for reliable starting and power.

Lesson 2 • Ignition system diagnosis

Teaches testing coil output, timing, and kill switch continuity to diagnose no-spark conditions. Ignition faults are among the most common causes of engine failure to start.

Lesson 3 • Routine maintenance procedures

Teaches oil changes, air filter service, spark plug replacement, and blade sharpening intervals. Scheduled maintenance prevents premature engine wear and costly repairs.

Lesson 4 • Engine disassembly and reassembly

Covers valve adjustment, piston and ring inspection, and torque sequence for engine reassembly. Correct reassembly restores compression and prevents oil leaks.

Lesson 1 • Agricultural electrical systems

Teaches battery service, charging system testing, wiring diagram reading, and circuit fault diagnosis. Electrical faults cause equipment downtime and can create fire hazards if unresolved.

Lesson 2 • Tractor systems overview

Introduces tractor drivetrain, PTO, three-point hitch, and hydraulic systems as integrated units. Systems-level thinking enables efficient diagnosis across multiple interacting components.

Lesson 3 • Hydraulic system maintenance

Covers fluid selection, filter service, cylinder inspection, and leak diagnosis for hydraulic systems. Hydraulic integrity is critical for safe implement control and lifting capacity.

Lesson 4 • Repair planning and documentation

Teaches creating repair orders, estimating parts and labour, and documenting completed work. Accurate records support warranty claims, resale value, and future maintenance planning.
