1. Pure Electric Drive with Autonomous Charging

The RM21 operates fully on electric power and autonomously returns to charge, requiring no operator involvement post-deployment. This enables zero-emission mowing with no fuel or oil usage, eliminates the risk of oil leaks or turf damage, and cuts down drastically on labour costs. Ideal for sustainability-focused businesses and large-scale operations needing hands-free maintenance.

2. Commercial-Grade Intelligence for Varied Terrain

Designed for complex commercial sites like sports fields, solar farms, orchards, turf farms, and large acreages, the mower uses a smart control system to adapt to diverse conditions. Delivers consistent, high-quality mowing across wide and varied terrain types, maximizing productivity and reducing the need for multiple machines. This flexibility supports multi-site operations and professional landscaping services.

3. RTK-Guided Precision with Optional LM01 Line Marking Kit

Offers centimeter-level accuracy through RTK positioning and can be bundled with the LM01 line marking kit, remote control, and base station. Allows the mower to not only perform precision mowing but also autonomously mark lines on sports fields—saving hours of manual marking time and ensuring perfect alignment. This dual functionality brings exceptional value to sports turf managers and field maintenance contractors.
