Accurate and Efficient Mowing

With centimeter-level positioning accuracy, our mowers can precisely cut grass, reducing the need for overlaps or skips. This results in faster and more efficient mowing.

Automatic Mowing on Complex Terrain

The RM21 uses LiDAR tech to create a 3D cloud point map of the terrain. This allows it to safely mow in complex areas, such as under trees or around objects.

One-click Multi-field Management

The RM21 can be used to mow multiple fields in a single task. This saves time and effort, making it easier to manage your property.

Smart Path Planning


The RM21 uses built-in object avoidance to automatically plan mowing paths. This helps prevent collisions and damage, making mowing safer and easier.
