Engineering-led.
Built by someone who has engineered advanced systems and operated them in demanding environments. We know what these machines can and can't do.
The FJD FRX is a commercial robotic mower for Perth and WA ovals, reserves, school grounds and golf turf. It cuts a 520 mm swath at 10 to 100 mm height, keeps about 20,000 m² cut every 24 hours from its dock, and holds a 25° working slope. Supplied, mapped and serviced from Perth, with mowing as a service from $50 a day.
Working in long grass, the studio view, the 25° slope test and the 10–100 mm cutting range.
The FRX removes the recurring labour of keeping commercial turf cut. Map an oval, a reserve or a fairway surround once and it mows on a schedule you set: 520 mm wide, 10 to 100 mm cutting height, the same lines every time, no operator. FJ Dynamics builds it for sports fields, golf courses and manicured public space, and we supply and service it across WA from Perth.
The commercial logic is per cut, not per month. A contractor cuts it once a week for $120 to $250 a visit; the FRX cuts it every day for about $50 a cut. Daily cutting is what changes the turf: clippings are short enough to disappear, growth stays even, and the surface reads as maintained every morning rather than the day after the mower visits. If your grounds are cut twice a week or more, or you carry grounds staff who should be on edges and gardens instead of laps, the numbers usually favour the robot.
One unit covers serious ground. A single 1 kWh battery cuts 8,000 m² over a 320-minute runtime, then the robot docks itself: in auto-charging trim the FRX Stationary keeps roughly 20,000 m² cut every 24 hours, about three football pitches. For bigger precincts the FRX Swap variant drops the dock for hot-swappable batteries rotated by site staff, lifting each unit to 32,000 m² per 24 hours. Most sites want Stationary; Swap earns its place on multi-unit deployments with people on the ground.
Navigation is RTK GNSS fused with vision, cutting to centimetre-accurate virtual boundaries with no perimeter wire to bury or break. The included FJD base station supplies corrections without relying on mobile coverage, and obstacle handling pairs the vision system with a physical bumper. The honest caveat: RTK wants open sky. Scattered trees are workable; dense canopy shadows the signal, so we survey tree cover before quoting and zone the map around it. Anti-theft is built in for open public sites: PIN lock, GPS tracking, geofencing and lift alarms.
The three details buyers ask about first: how it sees, how you watch it, and how it handles weather and hosing off.
The forward vision system flags people, animals and equipment in the cut path, with a physical bumper as the final backstop.
Progress, position and a live camera view from your phone; schedules and cutting height are set in the same app, over 4G.
Sealed to IPX5: Perth winter rain is within spec, and the deck hoses off at the end of a sandy week.
Open turf cut often is the sweet spot: ovals, reserves, surrounds and banks. If your site is mostly narrow verges under trees, we'll tell you at the survey.
Reserves, ovals and open turf kept at height daily, without adding crew to a roster that's already hard to fill.
Mows before school and after hours, so the oval is ready for period one and weekend sport without a contractor on site.
Roughs, green surrounds and the steep banks the fairway units skip. FJD's golf stack lists the FRX as its steep-terrain unit.
Training and match surfaces cut daily for even growth, with line-marking robots available under the same dashboard.
Common-area turf on a fixed daily cycle: one predictable arrangement instead of a variable contractor bill.
Village ovals and camp greens cut without FIFO grounds labour. For extreme-heat sites we scope the FJD Titan, rated to 55°C, alongside.
One site visit to survey and map, then the robot keeps the schedule. You watch coverage from the app; we watch the robot.
Free site check: area, gates, slopes, sky view for RTK and tree cover. If the site doesn't suit a robot, we say so before anyone signs anything.
We install the RTK base station, drive the boundary once and set zones, cutting heights, no-go areas and schedules. Virtual boundaries only; no buried wire.
The FRX cuts daily inside its map, steering around obstacles and finishing the pattern. You set the hours; it keeps them, in your chosen mowing angles.
It docks, fast-charges in 150 minutes and goes again. GreenMaster logs every cut; RaaS clients get the reporting without touching a dashboard.
Manufacturer figures from FJ Dynamics, not dealer-inflated ones. Site-specific coverage is confirmed at the survey.
Perth commercial mowing runs $120 to $250 a visit for a typical large site, and landscape trades sit on the national skills-shortage list: hiring a grounds crew in WA is hard, and getting harder. The FRX is the unit we lead with because its numbers work hardest: the strongest per-cut economics in the FJD range, an included RTK base station, and a 25° working slope that covers the banks most mowers avoid.
The established alternative is Husqvarna's CEORA 546 EPOS, listed at $55,899 including GST by a Perth dealer. It is a proven large-area machine with a genuine WA dealer network, and for a single large flat site bought outright it deserves a look. Our case is different: the FRX runs a comparable daily-cut programme on typical ovals at a fraction of that hardware price, ships with its RTK base station, and is available as a service from $50 a day rather than as capital expenditure only.
WA conditions get an honest read. IPX5 sealing handles Perth winter rain and end-of-week washdowns, and the 10 to 100 mm cutting range spans couch, kikuyu and buffalo mowing heights. FJ Dynamics publishes no operating-temperature figure for the FRX, so for sites that work through Pilbara summers we quote the FJD Titan, the one unit in the range rated to 55°C. There is no OEM guidance on sandy soils or coastal salt either; our survey and service schedule cover both.
Service distance matters more in mowing than in cleaning: the machines live outdoors, blades are consumables, and the main east-coast dealers do not ship robots to WA or install beyond their own metro areas. We supply and service FJ Dynamics robots across WA from Perth: survey, base-station install, mapping, blades, warranty handling and same-day metro response. If a unit is down, the person responsible is in your time zone.
No offshore tickets and no freight to Sydney. Perth-based engineers handle survey, deployment, training, mapping changes and incident response.
Free site check, RTK base-station install, boundary mapping, zones and schedules. We hand over a running system, not a crate.
On-site session for grounds staff and facility managers: the app, schedules, blade checks and the escalation flow.
Perth metro: same-day on-site. Regional WA: next business day. Cloud-resolvable issues: usually under an hour.
Mowing as a service from $50 a day, outright purchase with a Care Plan, or 2–4 year lease-to-own. Your call, quoted at survey.

Built by someone who has engineered advanced systems and operated them in demanding environments. We know what these machines can and can't do.
We deploy and service every unit ourselves across WA. If a robot's down at 2am on a mine site, that's on us, in the same time zone.
We recommend the right robot for your site, not the only one we carry.
RaaS is a flat monthly subscription, not a capital gamble. The risk sits with us, and you run the robot as often as you need.
FJ Dynamics films its mowers on user sites, not sound stages. This is the FRX on Japanese slope turf.
FRX in Japan: no slope too steep
Send us your site brief and we'll come back inside one business day with an indicative quote, a recommended set-up (one unit or several, Stationary or Swap), and a survey date.
The FRX is the volume unit of our FJD landscaping line. If your site needs marking, collection or more area per day, start here.
One chassis, four jobs: mow at 20 to 127 mm, line-mark, ball-pick and collect clippings. The schools and councils multi-tool.
730 mm cut, 108,000 m² per 72 hours and rated to 55°C. The mining-village and big-precinct unit.
Own the marking robot instead of paying per marking: a full pitch in about 30 to 40 minutes, on the same dashboard as the mowers.
The same three commercial models run our autonomous cleaning fleet: scrubbers and sweepers for warehouses, offices and camps. See the cleaning fleet.
