Quick answer
If your Husqvarna Automower 305 has cutting motor fault , investigate the fault systematically before replacing parts.
What matters on the Automower 305
This Automower generation normally relies on its installed boundary/guide system for navigation, so station status and loop conditions can be important when the symptom involves navigation or docking.
Use the exact error text shown by the mower or app. Similar wording across mower generations does not always mean the same component has failed.
Start with these checks
- Isolate the mower before inspecting the cutting system.
- Clear packed grass and debris from the cutting-disc area.
- Inspect blades and disc for visible damage.
- If the cutting system is clear but the fault persists, run the exact model diagnosis.
- Switch off and safely isolate the mower.
- Inspect the blade disc/cutting area for packed grass or foreign objects.
Stop if: the mower has damaged wiring, a swollen/damaged battery, severe vibration, water inside electrical areas, or would require opening sealed electronics.
Likely causes
Blocked cutting disc, worn cutting components, motor wiring or cutting-motor failure.
