Tractor & Agricultural Machinery Operations SWMS
Tractor and agricultural machinery operations — tractor pre-start, PTO implement attachment, slashing, ripping, baling, and terrain hazard management.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Tractor and agricultural machinery operations underpin Australian broadacre and mixed enterprise farming, but they remain the leading cause of on-farm fatalities, accounting for the majority of rollover, runover and entanglement deaths reported to Safe Work Australia each year. This SWMS covers tractor pre-start inspection, PTO-driven implement coupling, slashing, ripping, baling and operation across variable terrain including slopes, dam embankments and creek crossings. Under WHS Regulation 2025 r291, a Safe Work Method Statement is mandatory because the work constitutes High Risk Construction Work where powered mobile plant operates near workers and where there is risk of falling more than two metres on sloped ground or into excavations. The SWMS is further triggered by the use of plant capable of causing crush, entanglement and rollover injuries under r203–r215. PCBUs operating agricultural undertakings owe a primary duty of care under s19 of the WHS Act to eliminate or minimise these risks so far as is reasonably practicable, and a documented, consulted SWMS is the principal evidence of that discharge.
Hazards identified
7 hazards covered, sorted by priority.
Operator crushing fatality or catastrophic thoracic injury where ROPS is absent, folded or seatbelt unworn
Degloving, limb amputation or fatal scalping injury within seconds of loose clothing contact
Electrocution of operator and bystanders, arc-flash burns, plant fire and prolonged network outage
Fatal crushing or pelvic injuries from rear wheels and three-point linkage blind spots
Sudden tractor inversion into water or excavation causing drowning or entrapment
High-pressure fluid injection injury requiring surgical debridement and potential limb loss
Cognitive impairment leading to control errors, heatstroke collapse and secondary plant incidents
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Eliminate slope work above 15 degrees by re-planning paddock layouts, using fixed spray rigs, or contracting aerial application for inaccessible terrain.
- 2Elimination — Remove bystanders entirely from hitching zones by enforcing single-operator coupling protocols and locking out all foot traffic during reversing manoeuvres.
- 3Substitution — Substitute conventional driveline implements with hydraulically-driven attachments to remove PTO entanglement risk where mechanically and economically feasible.
- 4Substitution — Replace older pre-1981 tractors lacking certified ROPS with modern cab-equipped units compliant with AS 1636 and AS 1638 rollover protection structures.
- 5Engineering — Fit and maintain ROPS or FOPS conforming to AS 1636, ensure integral seatbelt operability, and install rear-view cameras plus reversing alarms on all units above 30 kW.
- 6Engineering — Install full-length PTO master shields, integral u-joint guards and implement input connection (IIC) shields per AS/NZS 4024.1601 before any rotating shaft is engaged.
- 7Administrative — Conduct documented daily pre-start inspections using the attached checklist, complete spotter protocols under powerlines maintaining 6.4m clearance per ENA NENS 04.
- 8Administrative — Restrict operation to workers holding verified competency (AHCMOM202 or equivalent), enforce maximum 10-hour shift limits and rotate operators during peak heat periods.
- 9PPE — Wear close-fitting cotton drill clothing without drawcords, AS/NZS 1801 hard hat when dismounted near loaders, and AS/NZS 1270 Class 5 hearing protection in open-station tractors.
- 10PPE — Use AS/NZS 1337.1 impact-rated eyewear during ripping and slashing, plus AS/NZS 2210.3 steel-cap boots with shank protection for implement coupling tasks.
Applicable Codes of Practice
Establishes inspection, guarding and isolation duties under WHS Reg r203–r215 directly applicable to PTO shafts, hydraulics and mobile plant.
Sets the benchmark for ROPS, seatbelt use, slope assessment and bystander exclusion zones referenced in WHS Reg r39 risk control hierarchy.
Defines the structural performance criteria for ROPS that PCBUs must verify before classifying a tractor as compliant under r214 plant duties.
Specifies the guarding geometry and interlock requirements for PTO drivelines and implement input connections relied on under r208 guarding clauses.
High-Risk Construction Work triggered
Tractors operating with attached slashers, balers and rippers create crush and runover zones for hitching assistants, livestock handlers and adjacent ground workers.
Raising loaders, balers and tipping trailers within tractor working envelope routinely encroaches the 6.4 metre no-go zone beneath rural overhead powerlines.
Three-point linkage and remote implement circuits operate at pressures exceeding 20 MPa, exposing operators to injection injury during coupling and maintenance.
PCBU must prepare, consult on and retain the SWMS for the duration of the work and two years post-incident; penalties for non-compliance are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
At a 1,200 hectare mixed cropping enterprise preparing for summer hay baling, the farm supervisor convenes a pre-start brief at the machinery shed at 5:45am with two operators and one casual hitching assistant. The SWMS is laid on the bonnet of the lead tractor and each hazard line is read aloud. When the team reaches the PTO entanglement entry, the assistant identifies that the round baler's input shield is cracked from the previous season — the SWMS control mandating AS/NZS 4024.1601 shielding triggers an immediate stand-down of that unit and substitution to the backup baler. The overhead powerline hazard prompts the supervisor to mark the paddock map with a no-raise corridor along the eastern boundary where the 22kV SWER line crosses, and all three workers sign onto the document acknowledging the 6.4 metre clearance rule. Mid-morning, ambient temperature climbs faster than forecast and the heat stress administrative control is invoked: operators rotate every 90 minutes instead of the planned two hours, and the SWMS is annotated in pen with the revised rotation, initialled, and photographed for the digital record. At smoko, the supervisor reviews the slope hazard before moving to the river paddock and confirms the 15-degree elimination threshold is not breached using a clinometer app, recording the reading on the SWMS reverse before resuming work.
