STIGA A 300: Cutting system blocked / poor cut

What this fault means

Packed grass, damaged blades or cutting-height mechanism can prevent normal cutting.

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

Step-by-step checks

1. Switch the robot off and isolate it before underside inspection.
2. Remove packed grass/debris from accessible cutting areas.
3. Inspect blades and fasteners for damage or seizure.
4. Raise cutting height temporarily if mowing overgrown grass.
5. Persistent motor/height errors with a free mechanism require service diagnosis.
