About this exam

The AUR30420 Certificate III in Agricultural Mechanical Technology is an Australian qualification for people who service and repair agricultural machinery in the automotive retail, service and repair industry. It suits apprentices, workshop employees and those moving into agricultural mechanical work who need to handle a broad range of tasks across engines, electrical systems, hydraulics, transmissions, braking, steering and final drives on farm plant and equipment. The qualification is delivered under the Automotive Retail, Service and Repair Training Package and is structured around 36 units: 21 core units plus 15 elective units. The core builds a common foundation in workplace safety, environmental practice, customer service, tool use, servicing operations and diagnostic strategy, together with engine, fuel injection, electrical, hydraulic, brake, steering and final drive competencies. Electives let candidates tailor the qualification toward particular machinery, systems or workshop tasks. No licensing, legislative or certification requirements apply, and there are no entry requirements. To prepare, work through the core units first because they underpin later diagnostic work, then choose electives that match the equipment you expect to service. Combine study with hands-on practice under supervision, and check with your registered training organisation about delivery mode, assessment arrangements and current unit availability.

What you'll study

Common questions

About Cert III Agricultural Mech preparation

How many units make up the AUR30420 qualification?

The qualification requires 36 units in total: 21 core units and 15 elective units. All 15 electives may be chosen from the elective list, and up to 6 of them may come from a Certificate II qualification or above in this Training Package or another endorsed Training Package or accredited course.

Are there any entry requirements for this qualification?

No. The national register lists entry requirements as nil, so there are no formal prerequisite units or prior qualifications you must hold before enrolling. Individual training providers may still apply their own enrolment conditions, so confirm arrangements with the provider you plan to study with.

Do I need a licence to work after completing it?

No licensing, legislative or certification requirements apply to this qualification at the time of publication. That said, individual job roles and state or territory rules can impose their own requirements, so check the specific requirements of any role or task you intend to perform.

What does the core study cover?

The 21 core units cover safe working practices, environmental and sustainability best practice, customer needs, tool and equipment use, servicing operations and diagnostic test strategies. Technical core units address basic electrical circuits, batteries, charging and starting systems, heavy vehicle compression ignition engines and diesel fuel injection, mobile plant hydraulics, braking, steering and final drives, powershift transmissions, cooling systems, engine servicing and braking system inspection.

How should I choose my elective units?

Pick electives that reflect the machinery and tasks you expect to encounter, since the rules require chosen units to be relevant to the work environment and qualification, to maintain AQF alignment, to avoid duplicating another unit's outcome and to contribute to a valid vocational outcome. Options range across agricultural equipment tyres and wheels, harvesting and seeding equipment, spraying equipment, transmissions, air conditioning and welding.

What is a sensible study order?

Start with the safety, environmental and customer service core units, then the tool use and servicing units, because they establish habits and routines used in every practical task. Move into electrical, engine and fuel system units once those basics are solid, then the mobile plant hydraulic, brake, steering and final drive units. Add electives alongside or afterwards to match your workplace equipment.

What generally causes candidates to struggle?

Common difficulties include weak diagnostic reasoning rather than poor hands-on skill, so practise forming and testing a diagnostic strategy instead of guessing at faults. Other frequent problems are gaps in electrical understanding, unfamiliarity with hydraulic systems, and treating safety and environmental units as paperwork rather than applying them in the workshop. Practise on real machinery under supervision wherever possible.

Can I get credit for units I already hold?

The packaging rules allow up to 6 elective units from a Certificate II qualification or above in this Training Package or another endorsed Training Package or accredited course. Whether specific prior units count is decided by your training provider through its recognition arrangements, so supply your records and ask before enrolment.

Is this the same as a heavy vehicle qualification?

No. This qualification focuses on agricultural machinery and mobile plant, though some units overlap with heavy vehicle work. Its core covers mobile plant hydraulic, braking, steering and final drive systems and powershift transmissions, and electives include agricultural equipment tyre, harvesting, seeding and spraying units that are specific to farm machinery.
