Stay stable on uneven turf
A front-suspension chassis supports stable operation, while the floating cutting deck follows ground contours for a more consistent cut.
FJDYNAMICS / VERSATILE TURF CARE
FJD Rough Ranger Versatile Robotic Mower
A versatile autonomous turf-care platform for mowing and specialist work across golf courses, sports pitches, driving ranges, estates and synthetic surfaces.
ONE PLATFORM / MORE TURF-CARE TASKS
Built for turf. Ready for more.
Rough Ranger combines stable autonomous mowing with interchangeable equipment for specialist work across natural and synthetic turf.
Manage multiple zones
Plan, manage and monitor several mowing areas in the app, then complete work across zones in a single task.
Plan efficient routes
RTK and LiDAR support 3D terrain mapping, smart path planning and 360° obstacle detection with front and rear bumpers.

NAVIGATION & AUTOMATION
Plan, monitor and protect every task.
Rough Ranger combines positioning, terrain awareness and physical protection to support repeatable autonomous work across complex sites.
RTK + LiDAR navigation
Fused positioning builds a 3D terrain map and supports work under trees or around obstacles where satellite reception can be more challenging.
Smart path planning
The platform automatically plans efficient routes to reduce overlap, missed areas and repeated manual route planning.
Multi-layer safety
Real-time 360° LiDAR obstacle detection works with front and rear physical bumpers during autonomous operation.

QUESTIONS & ANSWERS
Plan the right Rough Ranger setup.
We will confirm the site, machine specification and attachments before quoting.
How much ground can Rough Ranger mow?
The brochure states a theoretical maximum of 12,000 m² per charge and up to 108,000 m² over 72 hours in fast-charge mode. Actual output varies with terrain, grass condition, routing, charging and operating hours.
How does Rough Ranger navigate?
It combines RTK and LiDAR to build a 3D terrain map, plan efficient routes and support operation in signal-challenging areas such as under trees or around obstacles.
What cutting heights are available?
The published cutting-height range is 20–120 mm, with a 635 mm cutting width.
What slopes can it work on?
The brochure lists a 20° maximum working slope and a 15° recommended working slope. Routes on slopes should primarily run uphill and downhill; cross-slope mowing should be avoided or approached with caution.
Which attachments are available?
The current Rough Ranger ecosystem includes BP02 ball picking, LM03 line marking, GC01 grass collection, DB01 dew brushing and a Synthetic Turf Care Platform with configurable implements.
Can attachments operate at the same time?
Do not assume simultaneous operation. Attachment availability, configuration and installation requirements are confirmed when preparing your quotation.
Can I arrange a demonstration?
Yes. Tell Iron & Earth Equipment about the site, surface, access, mowing targets and attachment requirements so the team can discuss a suitable demonstration.
