Husqvarna Automower 320 NERA: Trapped

What this fault means

The mower cannot make progress because of terrain, obstacles, grass load or collision sensing.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Stop the mower and inspect the exact location where it stopped.
2. Remove loose obstacles and packed grass around wheels/cutting system without bypassing safety devices.
3. Check whether the location is a repeated narrow passage, hole, steep edge or soft ground.
4. Move the mower to open lawn and restart.
5. If Trapped appears immediately on open ground, especially after an update, record firmware and sensor status before assuming a drivetrain failure.
