Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Engine displacement, gear ratios, hydraulic pressure, electrical resistance, and fuel delivery rates all require calculation. These questions test your mechanical math: knowing which formula to apply, what units to use, and how to check your work.
Calibration: measure output in gallons per acre; adjust pressure/speed for target rate. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Vehicle systems use a wide range of specialty materials, fluids, and components that must meet OEM specifications. This section covers proper tool selection, component identification, and the material properties that determine service intervals and replacement requirements.
VRT: maps prescribe rates per area; equipment adjusts on-the-fly based on GPS position. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Yield sensors: flow meter + moisture sensor; GPS logs position creating digital yield data. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Diagnostic and repair procedures are systematic — skip a step and you'll miss the root cause. This section covers the proper approach to vehicle diagnosis, the sequence of mechanical repairs, and the testing methods that confirm a fix actually fixed the problem.
Settings: tight concave = more separation but damage risk; rotor speed similar balance. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
tight concave = more separation but damage risk
Planter maintenance: worn discs cause doubles/skips; depth adjustment critical for emergence. Troubleshooting is a systematic process: identify symptoms, narrow down causes logically, and verify your diagnosis before replacing parts. This logical approach is what examiners want to see.
