Robomow RX12U: Mower stuck / no drive

What this fault means

The mower cannot progress because of terrain or drive blockage.

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

Step-by-step checks

1. Power off and inspect wheels for debris.
2. Move the mower to flat open lawn.
3. Check if both wheels respond similarly.
4. Inspect repeated stop locations for holes, slopes and soft ground.
5. Single-wheel non-response on open ground requires drive service.
