A tree-heavy yard is primarily a navigation problem. Start by asking how the mower localizes when satellite visibility is limited.
Why trees change the shortlist
Dense canopy and nearby structures can complicate satellite-based positioning. That does not mean RTK automatically fails or LiDAR automatically wins: current mowers often combine several sensing methods and use different recovery strategies.
Current models worth investigating
- Mammotion LUBA 3 AWD: combines LiDAR, NetRTK and vision; Mammotion specifically positions its Tri-Fusion system for challenging environments including shaded areas.
- Mammotion LUBA mini 2 AWD: uses 360° LiDAR plus dual-camera vision and is aimed at smaller complex gardens.
- Navimow X4: combines Network RTK with panoramic vision and avoids a local RTK antenna installation.
Check these before buying
- Can the mower navigate the most shaded section?
- What sensing remains available when satellite quality drops?
- Are there narrow corridors between trees or structures?
- Can it manage all required zones?
- Does its slope and area capacity still fit the property?
