FJD RM21 multi-functional robotic mower

Description

The RM21 is the workhorse of the FJDynamics commercial range – a fully electric, fully autonomous mower built for the turf that eats labour hours: large sports pitches, golf roughs and surrounds, sod farms and estate grounds.

Its RTK and LiDAR navigation work together to hold position to within a couple of centimetres, including under dense tree canopy and in signal-shadowed corners where GPS alone gives up. One charge covers up to 3 acres (12,000 m²); run around the clock in fast-charge mode and it will cover up to 26 acres in 72 hours. A 360-degree LiDAR field plus front and rear bumpers handle obstacle detection, and ongoing tuning has improved avoidance of small animals such as hedgehogs.

The same platform takes four FJD attachment kits — dew brush, ball picker, line marker and grass collector — so a single machine can do far more than mow.

Quiet, zero-emission and managed entirely from a phone or tablet, the RM21 turns a recurring staffing problem into a scheduled background task.
