RM21
Large-area mower covering 13000 square metres per charge.

Overview
The RM21 is a high-capacity mower for large grounds, covering up to 13000 square metres on a single charge from its 4 kWh battery. Smart path planning and one-click multi-zone control let one operator manage several areas at once.
Centimetre-level positioning from RTK and LiDAR gives exceptional precision, and the mower detects terrain, obstacles and trees automatically for safe cutting on complex surfaces. It handles slopes up to 20 degrees.
360 degree obstacle detection, collision and lift sensors and rain protection keep operation safe, while automatic charging returns it to the dock when low and resumes work afterward. A cutting height of 30 to 127 mm suits varied grounds.
