Lawn Mowing SWMS
Ride-on and push mower operation on residential and commercial sites. Covers projectile hazards, uneven ground, operator fatigue, and noise exposure.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Lawn mowing using ride-on and push mowers is a routine but deceptively hazardous activity carried out across residential properties, commercial premises, schools, sporting facilities, parks, and council reserves. The work involves operating petrol or battery-powered rotary cutting equipment in environments where ground conditions, projectile risks, noise levels, and operator fatigue all combine to create a workplace with a higher injury rate than many people assume. Safe Work Australia data consistently shows that powered garden equipment is associated with serious lacerations, eye injuries, hearing loss, and rollover fatalities — particularly with ride-on machines on slopes.
Under the model Work Health and Safety Act 2011 and the WHS Regulation 2025 (Part 4.1 — Managing Risks of Hazardous Work), a Person Conducting a Business or Undertaking (PCBU) must identify reasonably foreseeable hazards, eliminate risks so far as is reasonably practicable, and where elimination is not possible, minimise risks using the hierarchy of control. Lawn mowing involves plant (mowers), noise (typically 85–105 dB(A)), hazardous chemicals (petrol), and mobile plant — each of which is regulated under specific Parts of the WHS Regulation.
While lawn mowing is not classified as High Risk Construction Work under section 291 of the WHS Regulation, a documented Safe Work Method Statement is still required by most principal contractors, councils, facility managers, and commercial clients as a contractual and due-diligence requirement. It is also the most defensible way for a PCBU to demonstrate compliance with the primary duty of care under section 19 of the WHS Act if an incident occurs.
Hazards identified
7 hazards covered, sorted by priority.
Penetrating eye injury, lacerations to operator or bystanders, broken windows or vehicle damage
Crush injuries, fatal entrapment under machine, amputation from contact with blades
Severe lacerations, finger or hand amputation, degloving injuries
Permanent noise-induced hearing loss and tinnitus (compensable under workers compensation schemes)
Lower back strain, hand-arm vibration syndrome (HAVS), shoulder injuries
Burns from hot engine ignition of fuel, chemical exposure, fire damage to property
Heat exhaustion, heat stroke, reduced reaction time leading to secondary incidents
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Conduct a documented pre-start site inspection to identify and remove projectile hazards (stones, wire, irrigation fittings, pet toys, dog faeces, hidden timber) before starting the mower
- 2Inspect mower before each use: blade condition, deck integrity, discharge chute and grass-catcher fitted, ROPS in place on ride-ons, seatbelt functional, dead-man switch operational
- 3Do not mow slopes greater than 15 degrees with ride-on mowers; use push mowers across the slope (not up/down) on gradients up to 20 degrees and refuse work on steeper terrain
- 4Mandatory PPE: AS/NZS 1337.1 safety glasses, AS/NZS 1270 Class 5 hearing protection, steel-cap boots compliant with AS/NZS 2210.3, long trousers, hi-vis shirt, and gloves during maintenance
- 5Establish a 10-metre exclusion zone around operating mowers; stop mowing immediately if any person, pet or vehicle enters the zone
- 6Always shut down engine, remove ignition key, and wait for blades to fully stop before clearing blockages, inspecting the deck, or refuelling — lockout the spark plug lead for any maintenance
- 7Refuel only on cool engines on level ground away from ignition sources; store petrol in AS/NZS 2906 compliant jerry cans and transport per ADG Code requirements
- 8Implement fatigue and heat management: scheduled rest breaks every 60–90 minutes, electrolyte hydration, rescheduling work to cooler parts of the day when forecast exceeds 35°C
- 9Provide and document operator training and competency assessment for each mower model used, including ride-on licensing where required by the PCBU
- 10Audiometric testing to be offered within 3 months of commencement and every 2 years thereafter, as required under WHS Regulation r.58 for workers required to use hearing protection

Worked example
Daniel runs a two-person mowing business contracted to maintain 14 strata-managed townhouse complexes in suburban Brisbane. Before commencing the Tuesday run at a complex in Carindale, he opens this SWMS on his iPad, walks the site with his offsider Jamie, and identifies a section of common lawn that slopes toward a retaining wall. Per the controls listed, Daniel decides the 18-degree slope is too steep for the ride-on and they will use the push mower across the gradient. They also pick up two irrigation sprinkler heads and a child's metal scooter that would have become projectiles. Both workers sign the SWMS sign-on register, fit Class 5 earmuffs and impact-rated safety glasses, and complete the pre-start checklist confirming the ride-on's ROPS bar is up and seatbelt is functional. Mid-morning, a resident walks a dog onto the lawn — Jamie immediately disengages the blades and idles the engine until the 10-metre exclusion zone is clear. When the strata manager later requests evidence of safe work practices following a neighbour complaint, Daniel emails the completed SWMS, sign-on register and inspection checklist, satisfying the body corporate's contractor compliance requirements.

Frequently asked questions
Is a SWMS legally required for lawn mowing?
Not as high risk construction work. Mowing lawns is not construction work, so it does not meet section 291 of the WHS Regulation and the section 299 SWMS duty is not what applies. The duties that do apply are the primary duty under section 19 of the WHS Act, plus the plant, noise and hazardous chemical provisions covering mowers, petrol and exposure above the noise standard. In practice most councils, facility managers, strata committees and principal contractors require a documented method statement before they will let a contractor on site, and it is the most defensible evidence of your system if an incident occurs.
How steep is too steep for a ride-on mower?
The template draws the line at 15 degrees for ride-ons. Above that, a push mower is used across the gradient rather than up and down, to a limit of 20 degrees, and steeper ground is refused rather than attempted. Rollover on slopes, embankments and near retaining walls is a high-priority hazard because the machine traps the operator underneath it and the blades are still turning. That is why the pre-start inspection specifically checks that the ROPS bar is up and the seatbelt works. In the worked example an 18-degree section falling toward a retaining wall is mowed with the push mower across the slope.
How do we stop the mower throwing something at a bystander?
With a documented pre-start sweep and a maintained exclusion zone, in that order. The sweep walks the area and removes stones, wire, glass, irrigation and sprinkler fittings, hidden timber and the assorted objects that turn up on residential lawns, before the mower is started rather than while it is running. The deck must have its discharge chute or grass catcher correctly fitted. A 10 metre exclusion zone then applies around the operating machine, and the rule is to disengage the blades immediately if any person, pet or vehicle enters it, which on strata and school work happens more often than crews expect.
Do mowing crews need hearing tests?
Yes, where they are required to wear hearing protection. Mowers commonly run at 95 to 105 dB(A), well above the 85 dB(A) eight-hour exposure standard, so the noise provisions bring audiometric testing with them. The template's schedule offers testing within three months of a worker starting and every two years afterwards, alongside Class 5 hearing protection. Testing is not the control, though. It measures whether the controls worked. Quieter plant, limiting continuous exposure and rotating tasks are what actually reduce the dose, and hearing loss from mowing is compensable and permanent.
What about petrol handling, and what do I receive?
Refuelling happens only on a cool engine, on level ground, away from ignition sources, with fuel stored in compliant jerry cans and transported in line with the dangerous goods requirements for carrying petrol in a work vehicle. Heat is managed by rescheduling to cooler parts of the day when the forecast passes 35 degrees, with rest breaks every 60 to 90 minutes. You receive a fully editable Microsoft Word document, bought once, with the hazard register and risk ratings, a state-specific legislation schedule, a worker sign-on register and a daily pre-start inspection checklist covering both ride-on and push mowers.
