RTK + LiDAR

No signal worries

RTK fused with LiDAR keeps the RM21 accurate under trees and in signal-challenging areas, and it returns to its charging station automatically when the battery runs low.

Protection

Layered safety

Real-time 360° LiDAR obstacle detection works with front and rear physical bumpers. FJD has tuned detection for small animals, including hedgehogs.

Line marking for sports clubs

The LM01 Line Marker Kit turns the RM21 into a field marker, delivering clear, consistent lines within tight maintenance windows. FJD calls the pairing the RM21 Combo.

Questions buyers ask

Frequently asked questions

Which attachment kits fit the RM21?

FJ Dynamics pairs the RM21 with the BP01 Ball Picker Kit and the LM01 Line Marker Kit. FJD's RM21 page also shows the GC01 Grass Collector and DB01 Dew Brush kits, but those kit pages describe them for the Rough Ranger, so we confirm their RM21 fit with your quote. The newer BP02 and LM03 kits are for the Rough Ranger only.

RM21 or Rough Ranger?

Both are 25-inch, 4 kWh, 3-acre-per-charge RTK + LiDAR platforms. The Rough Ranger is FJD's newer platform, with a front suspension chassis, floating deck and the BP02/LM03 kits; the RM21 uses BP01/LM01 and has a 20–127 mm cutting range. We can quote either, or help you choose.

Does it need an RTK base station or subscription?

It navigates on RTK fused with LiDAR, so it needs an RTK correction source. FJD does not publish whether a base station or network service is included, so we confirm the correction setup for your site with your quote.

How much can it mow?

Up to 12,000 m² (3 acres) per charge and up to 108,000 m² (26.7 acres) in 72 hours in fast-charging mode (93,600 m² standard). These are FJD theoretical values based on 24-hour use.

Is it safe around wildlife?

FJD has optimized the 360° LiDAR detection for small animals including hedgehogs, alongside front and rear bumpers. FJD still advises inspecting turf before mowing and avoiding unattended night-time operation.

What warranty applies?

Warranty terms are set by FJ Dynamics and confirmed with your quote. OmniNova is an independent retailer and handles claims with the manufacturer for you.
