Agric Equipment Mechanic study plan

List the safety practices for pre-start walkarounds, PTO guarding, and hydraulic lockout, then state the hazard each one controls

Identify the major components of a four-stroke compression-ignition engine and describe the function of each in your own words

Trace the air path from intake through turbocharger, aftercooler, and manifold, and explain how a restriction at each point changes engine behavior

Explain the difference between direct and indirect injection and the diagnostic implications of each

Describe the low-pressure and high-pressure sides of a common-rail fuel system and the sensors that regulate each

Diagnose three common no-start or low-power complaints by ordering fuel, air, and compression checks logically

Explain how to bleed a fuel system after filter replacement and when priming is required

Interpret a fuel-pressure and return-flow test result and state the likely faulty component

Explain the operation of the cooling system and thermostat, and describe how to test for a failed head gasket versus a stuck thermostat

Identify the components of a powershift transmission and describe how clutch packs are engaged hydraulically

Compare synchromesh, powershift, and hydrostatic drives by application and by failure mode

Describe the correct procedure for checking and adjusting clutch linkage free play on a mechanical transmission

Trace power flow from engine through flywheel, damper, transmission, differential, and final drive

Explain the function of differential lock and how to test that it engages and releases

Identify the main components of an open-center and a closed-center hydraulic system and state how each responds to a deadheaded cylinder

Explain how to set and verify system relief pressure using a gauge and flow meter

Diagnose slow hydraulic operation by testing pump flow, relief pressure, and cylinder bypass in a logical order

Explain how to read a hydraulic schematic and locate the valve that controls a specified function

Describe battery testing by state of charge and load, plus correct charging-system voltage checks

Explain the role of the alternator, regulator, and fusible links in a machine charging circuit

Trace a starting circuit from key switch through neutral safety switch, relay, and starter, and explain how to isolate an open circuit

Interpret CAN bus fault symptoms and describe basic continuity and termination-resistance checks

Explain how to inspect and adjust service brakes and park brake on a typical tractor

Describe steering system checks for a hydrostatic steering unit, including orbit motor and priority valve behavior

Explain tire load ratings, inflation pressure effects, and correct ballasting for a given field and road use

Describe track tension adjustment and the wear indicators to inspect on rubber tracks and undercarriage

Explain the basic refrigeration cycle and describe how to check vent temperature and system pressures

Describe how a GPS guidance receiver, display, and auto-steer system interact, and how to verify section control on an implement

Apply a structured inspection routine to a machine and document findings in a written condition report

Write repair orders that state complaint, cause, and correction clearly for three sample faults

Complete two timed mixed-domain practice exams and log every missed item by domain

Review the weakest two domains and re-explain each missed concept aloud without notes
